What Is Sepsis? Watch for Emergency Signs of an Infection That Can Worsen Quickly

Sepsis often starts with an infection that seems ordinary, such as a cough with fever, a urinary tract infection, an inflamed wound, or a general feeling of growing weakness. However, in some people, an infection can trigger an overly strong body response that disrupts how the organs work. That is why sepsis needs to be recognized as a medical emergency, not just an infection that “will get better eventually”. Sepsis occurs when the body’s response to an infection causes organ dysfunction, and it can worsen if it is not recognized and treated quickly.

If you are reading this article because you are worried about yourself, a parent, a partner, a child, or another family member, pay attention to changes in the body’s overall condition. Symptoms to watch for may include fever or a very low body temperature, chills, rapid breathing, shortness of breath, palpitations or a very fast heart rate, confusion, extreme weakness, cold or clammy skin, severe pain, and a much lower urine output. Sepsis may be accompanied by confusion, feeling extremely unwell, fever or chills, a high heart rate, a weak pulse, and shortness of breath.

However, it is important to remember: this article aims to help you understand the warning signs, not to replace an in-person examination by a doctor. Sepsis cannot be confirmed from a single symptom or from information read online. Medical professionals need to assess the patient’s condition as a whole, including blood pressure, breathing, heart rate, body temperature, level of consciousness, urine output, the possible source of infection, and signs of organ dysfunction. Sepsis is a clinical diagnosis and should not be confirmed or ruled out based on a single test alone.

In the context of heart health, sepsis deserves special attention because this condition can affect blood pressure, blood flow, heart rate, and organ function. When blood pressure drops or circulation is disrupted, vital organs may not receive enough blood and oxygen. As a result, the heart may work harder to help maintain blood flow throughout the body. Signs of sepsis can include a fast heart rate, low blood pressure, rapid breathing, and reduced urine output.

By recognizing sepsis earlier, families can make medical decisions more quickly and appropriately. Next, this article will help you understand what sepsis is, why this condition can be dangerous, which symptoms to watch for, and when an infection should be checked right away in the emergency department (ER).

What Is Sepsis?

Sepsis is a medical emergency in which the body responds to an infection excessively, to the point that it starts to disrupt organ function. So the problem is not only the infection itself, but also the body’s reaction, which becomes too strong and is no longer under control. Sepsis can occur when the body’s response to an infection causes organ dysfunction, and it can progress to shock, multiple organ failure, or death if it is not recognized and treated quickly.

The body does have a defense system to fight germs. However, in sepsis, this defensive response can instead trigger widespread inflammation. As a result, blood flow may be disrupted, blood pressure may drop, and body tissues may not get enough oxygen and nutrients. That is why sepsis is not just an “ordinary infection” that can be monitored indefinitely, especially if the patient’s condition worsens quickly. Sepsis may be accompanied by signs such as rapid breathing, a fast heart rate, low blood pressure, and reduced urine output.

Sepsis can start from many types of infection, including lung infections, urinary tract infections, skin or wound infections, and digestive tract infections. The Centers for Disease Control and Prevention states that infections that lead to sepsis often start in the digestive tract, lungs, skin, or urinary tract. Even so, not every infection will become sepsis. What needs watching is when an infection starts to be accompanied by signs that the whole body is affected, such as rapid breathing, confusion, extreme weakness, a racing heart, a drop in blood pressure, or very little urine.

In addition, some people need to be more watchful when they have an infection. Older adults, babies, pregnant or postpartum women, hospitalized patients, ICU patients, people with weakened immune systems, and people with chronic diseases are among the groups at higher risk of sepsis. In these groups, an infection that seems mild at first may worsen more quickly or be harder to recognize early on.

Put simply, the difference can be understood like this:

• Infection occurs when germs enter and multiply in the body.
• Sepsis occurs when the body’s response to an infection becomes excessive and starts to disrupt organ function.
• Septic shock is a more severe form of sepsis, in which blood pressure and circulation are seriously disrupted.

That is why sepsis needs to be treated as a condition that requires prompt medical assessment. The Surviving Sepsis Campaign emphasizes that patients with sepsis or septic shock need to be assessed and treated immediately, including through an evaluation of the source of infection and the body’s overall condition.

Is Sepsis the Same as a Blood Infection?

Many people refer to sepsis as a “blood infection”. This is understandable, because in everyday conversation people often use “blood infection” to describe an infection that feels severe, is spreading, or is worrying. Medically, however, sepsis is not just an infection in the blood. Sepsis is a condition in which the body responds very severely to an infection, and that response then starts to disrupt organ function. Sepsis occurs when the body’s response to an infection causes organ dysfunction, and it can progress to shock or multiple organ failure if it is not recognized and treated quickly.

In other words, the main problem in sepsis is not simply “germs in the blood”. The bigger problem is the body’s reaction to the infection. In this condition, the inflammatory response that is supposed to help fight germs can instead spread, disrupt blood flow, lower blood pressure, and leave organs without enough oxygen and nutrients. That is why sepsis needs to be understood as a medical emergency, not just an ordinary infection that can keep being monitored without evaluation.

In addition, the infection that triggers sepsis does not always start in the blood. Infections that lead to sepsis most often start in the digestive tract, lungs, skin, or urinary tract. Several sources of infection can cause sepsis, including the lungs, the kidneys or bladder, the digestive system, the bloodstream, catheter sites, wounds, or burns.

To make it easier to understand, here are the differences:

Term	Simple Meaning	Important Note
Infection	Germs enter and multiply in the body.	Can occur in the lungs, urinary tract, skin, wounds, digestive tract, or other areas.
Blood Infection	A lay term often used to describe an infection that feels severe or worrying.	The term is easy to understand, but it does not necessarily describe the medical condition fully.
Sepsis	A severe body response to an infection that starts to disrupt organ function.	Can occur even if the original source of infection is not in the blood.
Septic Shock	A more severe form of sepsis, in which blood pressure and circulation are seriously disrupted.	Requires immediate medical treatment.

So if you or your family have heard the term “blood infection”, there is no need to consider it wrong in everyday conversation. Even so, it is important to understand that sepsis is broader than an infection in the blood. This condition can start from pneumonia, a urinary tract infection, a skin infection, a wound infection, or a digestive tract infection. Some infections that commonly cause sepsis include pneumonia, urinary tract infections, skin infections, and digestive tract infections.

03 / Related Conditions

What Is Septic Shock?

Septic shock is a more severe form of sepsis, in which blood pressure drops very low and circulation is seriously disrupted. At this stage, the body is not only fighting an infection but also starting to struggle to maintain enough blood flow to vital organs. That is why septic shock is an emergency that requires immediate medical treatment. Sepsis and septic shock are medical emergencies that need to be recognized and treated promptly.

In sepsis, the body’s response to an infection can become too strong and disrupt organ function. In septic shock, however, the disruption already involves blood pressure and circulation more severely. As a result, organs such as the brain, kidneys, lungs, liver, and heart may not get the blood flow and oxygen they need to work properly. Sepsis can lead to shock, multiple organ failure, and death if it is not recognized and treated quickly.

Put simply, the difference can be understood like this:

Stage	Simple Explanation	What to Watch For
Infection	Germs enter and multiply in the body.	Fever, pain, cough, an inflamed wound, or symptoms depending on the source of infection.
Sepsis	The body’s response to an infection becomes excessive and starts to disrupt organ function.	Rapid breathing, confusion, fast heart rate, extreme weakness, reduced urine output.
Septic Shock	Sepsis worsens until blood pressure and circulation are seriously disrupted.	Very low blood pressure, fainting, weak pulse, cold skin, decreased consciousness, very little urine.

Why is low blood pressure dangerous? Because blood carries oxygen and nutrients throughout the body. If blood pressure drops too low, vital organs do not get an adequate supply. In sepsis, blood flow can be impaired so that vital organs do not receive the nutrients and oxygen they need; in severe cases, this can progress to a drastic drop in blood pressure, or septic shock.

Septic shock does not occur in every patient with sepsis. Even so, its signs should not be ignored. Seek medical help right away if an infection is accompanied by fainting, very low blood pressure, a weak pulse, rapid breathing, shortness of breath, cold or clammy skin, confusion, extreme weakness, or very little urine. Sepsis is a medical emergency that can quickly progress to tissue damage, organ failure, and death if it is not treated promptly.

Sepsis Symptoms to Watch For

Sepsis symptoms can differ from person to person. In some patients, the complaints look like an ordinary severe infection: fever, chills, weakness, or pain. However, the symptoms become more worrying when the infection starts to be accompanied by changes in breathing, consciousness, heart rate, blood pressure, skin, or the amount of urine.

Not every fever means sepsis. Fever does often appear when the body is fighting an infection. However, if fever is accompanied by rapid breathing, shortness of breath, a racing heart, confusion, extreme weakness, cold or clammy skin, severe pain, or reduced urine output, the condition needs to be assessed by a medical professional right away. Sepsis can present with different signs over time, and anyone suspected of having sepsis needs to receive medical care immediately.

Main Signs of Sepsis

Look at the overall pattern of symptoms, not just one complaint. Seek medical help right away if an infection is accompanied by one or more of the following signs, especially if the patient’s condition worsens quickly:

• High fever or the body feels very hot.
• Very low body temperature, especially in older adults, babies, or patients with weakened immune systems.
• Chills or feeling very cold.
• Rapid breathing or visibly working hard to breathe.
• Shortness of breath.
• Fast heart rate, palpitations, or a weak pulse.
• Extreme weakness, looking drained of energy, or having difficulty doing usual activities.
• Cold, clammy, pale, or sweaty skin.
• Confusion, speaking incoherently, severe drowsiness, or being hard to wake up.
• Reduced urine output, for example urinating much less often.
• Severe pain or discomfort that feels unusual.
• Rapidly worsening condition, even if it initially looked like an ordinary infection.

Why Is a Combination of Symptoms More Important Than a Single Sign?

Sepsis often does not appear with one very obvious sign. That is why families need to look at changes in the person’s condition as a whole.

For example, someone who initially only has a fever then becomes very weak, breathes faster and faster, looks confused, and rarely urinates. A pattern like this is more worrying than a mild fever that improves with care as recommended by a doctor.

In addition, do not focus only on the thermometer reading. Also pay attention to:

1. whether the patient seems “not their usual self”;
2. whether their breathing is getting faster or heavier;
3. whether the patient is becoming confused or hard to talk to;
4. whether their skin has become cold, pale, clammy, or sweaty;
5. whether they are passing much less urine than usual;
6. whether they seem very weak or are worsening quickly.

In children, symptoms can be harder to recognize because children may not be able to explain how they feel. IDAI (Indonesian Pediatric Society) explains that the symptoms of sepsis in children can be nonspecific and varied, including high fever or a low body temperature in young infants, weakness or sleeping all the time, confusion, rapid breathing or shortness of breath, a very fast or very slow heart rate, pale skin, severe pain, and passing little urine.

When Do Infection Symptoms Become a Warning Sign?

An infection needs to be checked right away if symptoms develop quickly or start to affect how the whole body functions. The most important signs not to ignore are:

• changes in breathing: faster, heavier, or short of breath;
• changes in consciousness: confusion, severe drowsiness, being hard to wake up;
• impaired circulation: cold skin, weak pulse, low blood pressure, fainting;
• the heart working faster: a very fast heart rate or a strong pounding heartbeat;
• reduced urine output: urinating much less than usual.

These symptoms matter because sepsis can disrupt blood flow and organ function. That is why, if an infection is accompanied by changes in breathing, consciousness, blood pressure, heart rate, or urine output, do not wait until the condition becomes more severe.

Sepsis Symptoms in Adults

In adults, sepsis symptoms often feel like a severe flu or an infection that keeps getting worse. Early complaints may include fever, chills, extreme weakness, or pain. However, warning signs appear when these complaints develop into a broader pattern: breathing gets faster, the heart races, consciousness changes, the body feels very weak, or urine output is much lower than usual.

A single symptom does not necessarily mean sepsis. However, in adults, sepsis should be suspected if an infection is accompanied by several severe systemic signs or worsens quickly. Sepsis can cause signs such as fever or a low temperature, chills, confusion, difficulty breathing, clammy skin, severe pain, a high heart rate, a weak pulse or low blood pressure, and low urine output.

Warning Signs to Look Out for in Adults

Seek medical help right away if an infection is accompanied by one or more of the following signs, especially if the condition worsens within a short time:

• High fever or the body feels very hot.
• Chills or feeling very cold.
• Rapid breathing or breathing that feels heavier than usual.
• Shortness of breath, especially when it appears together with extreme weakness.
• Fast heart rate or a pounding heart.
• Confusion, difficulty focusing, speaking incoherently, or appearing very drowsy.
• Extreme weakness, to the point of having difficulty standing, walking, or doing usual activities.
• Reduced urine output, for example urinating much less often.
• Cold, clammy, pale, or sweaty skin.
• Severe pain or discomfort that feels unusual.
• Rapidly worsening condition, even if it initially looked like an ordinary infection.

Don’t Look Only at the Fever

Fever often appears when the body is fighting an infection. However, not every fever means sepsis. On the other hand, sepsis is not always marked by a high fever either. In some people, the body may instead feel very cold, or the symptoms may seem nonspecific at first.

That is why you should pay attention to changes in the person’s overall condition. For example, someone who initially only has a fever then starts breathing rapidly, has a pounding heart, looks confused, becomes very weak, and rarely urinates. A pattern like this is more worrying than a mild fever that improves with care as recommended by a doctor.

When Do Symptoms in Adults Become a Warning Sign?

Infection symptoms in adults need to be checked right away if they start to affect how the whole body functions. The most important signs not to ignore include:

• changes in breathing: faster, heavier, or short of breath;
• changes in consciousness: confusion, severe drowsiness, difficulty focusing, or being hard to talk to;
• the heart working faster: a very fast heart rate or a strong pounding heartbeat;
• impaired circulation: weak pulse, cold skin, severe dizziness, fainting, or low blood pressure;
• reduced urine output: urinating much less than usual;
• overall condition worsening: extreme weakness or seeming “not their usual self”.

These signs matter because sepsis can disrupt blood flow and organ function. In addition, medical professionals assess sepsis through a physical examination for findings such as fever, an increased heart rate, low blood pressure, and difficulty breathing, as well as tests to look for signs of infection or organ damage.

Sepsis Symptoms in Older Adults

In older adults, sepsis symptoms can be more subtle and do not always look like a severe infection. The fever may not be high. Complaints of pain may also be unclear. In fact, the early signs that families notice are often just sudden changes: an elderly parent seems more confused, very weak, refuses to eat, or seems “not their usual self”.

This matters because older adults are among the groups more vulnerable to sepsis. Adults aged 65 and older are among those at higher risk, especially if they have a chronic disease, a weakened immune system, or have recently had a serious illness, surgery, or a hospital stay.

Signs of Sepsis to Watch for in Older Adults

In older adults, do not just wait for a high fever. Sepsis symptoms in older adults may show up as small changes that appear suddenly or worsen quickly, such as:

• Sudden confusion, seeming disoriented, speaking incoherently, or having difficulty focusing.
• Extreme weakness, much weaker than usual, having difficulty standing, or having difficulty walking.
• Loss of appetite, not wanting to eat or drink as usual.
• Body temperature is not always high; some older adults may instead seem very cold or have a lower body temperature than usual.
• Reduced urine output, for example urinating much less often.
• Worsening of chronic conditions, such as increasing shortness of breath, blood sugar that is hard to control, heart symptoms that feel worse, or blood pressure that seems unstable.

Don’t Dismiss Sudden Changes as “Just Old Age”

Families often ask a question like this: “Is this just because of age, or is it a sign of a serious infection?” The answer is not always easy. However, sudden changes in older adults should not be immediately dismissed as part of normal aging.

For example, an elderly parent who can usually still eat, speak clearly, or walk on their own suddenly becomes very drowsy, refuses to eat, seems confused, breathes rapidly, or rarely urinates. A pattern like this calls for closer attention, especially if there were earlier signs of infection such as a cough, pain when urinating, a worsening wound, diarrhea, fever, or chills.

In addition, the signs of sepsis can differ from person to person and may include changes in mental status, rapid breathing, chills, sweating for no clear reason, and symptoms related to the source of infection. Being over 65 years old and having chronic diseases such as diabetes, kidney disease, or lung disease can increase a person’s risk of developing sepsis.

When Should Families Seek Help Right Away?

Seek medical help right away if an older adult with an infection or suspected infection has:

• sudden confusion or decreased consciousness;
• extreme weakness or difficulty waking up;
• rapid breathing, shortness of breath, or visibly working hard to breathe;
• a very fast heart rate or a weak pulse;
• cold, pale, clammy, or sweaty skin;
• very little urine;
• low blood pressure, severe dizziness, or fainting;
• a chronic disease that is worsening quickly.

Sepsis Symptoms in Children

In children, sepsis symptoms can be harder to recognize because children may not be able to explain what they feel. Babies may only seem unwilling to breastfeed. Older children may look very weak, be fussier, be drowsy all the time, or seem “not their usual self”. That is why parents need to watch for changes in behavior, breathing pattern, skin color, fluid intake, and the amount of urine, rather than just waiting for a high fever.

IDAI explains that the symptoms of sepsis in children are often nonspecific and can vary. Signs that may appear include a high fever, a low body temperature in young infants, weakness or sleeping all the time, seeming confused, rapid breathing or shortness of breath, a very fast or very slow heart rate, pale skin, severe pain, passing little urine, a baby refusing to breastfeed, and even seizures or decreased consciousness.

Signs of Sepsis to Watch for in Children

Have your child checked right away if a fever or infection is accompanied by one or more of the following signs, especially if the condition worsens quickly:

• Rapid breathing, shortness of breath, or visible pulling in of the chest wall when breathing (chest indrawing).
• Difficulty waking up, sleeping all the time, extreme drowsiness, or decreased consciousness.
• Looking very weak, inactive, not as responsive as usual, or looking “floppy”.
• Pale, cold, clammy, or bluish skin.
• Refusing to drink or breastfeed, especially when accompanied by weakness or signs of dehydration.
• Reduced urine output, for example a diaper that stays dry longer than usual or an older child who rarely urinates.
• Seizures, especially when accompanied by fever, extreme weakness, or difficulty regaining consciousness.

Why Do Changes in a Child’s Behavior Matter?

In children, changes in behavior are often a very meaningful early clue. Parents usually know their child’s daily patterns more closely than anyone: when the child is active, how they respond, how strongly they breastfeed or drink, and how often they urinate.

That is why noticeable changes should not be ignored. For example, a child who is usually active suddenly only wants to sleep, refuses to drink, breathes rapidly, has skin that looks pale or feels cold, and passes less urine. A pattern like this is more worrying than a mild fever in a child who still seems active, is willing to drink, and is improving with care as recommended by a doctor.

When Should a Child Go to the ER Right Away?

Take your child to the ER or a hospital right away if warning signs appear, such as:

• seizures;
• difficulty waking up or sleeping continuously;
• shortness of breath or visible chest indrawing when breathing;
• very cold, pale, or bluish skin;
• not urinating for a long time;
• refusing to drink or breastfeed, together with weakness;
• persistent vomiting;
• high fever in a young infant;
• the child’s condition seems to be worsening quickly.

IDAI advises taking a child to the ER or a hospital right away if the child has seizures, sleeps continuously and is hard to wake, has shortness of breath with chest indrawing, shows signs of severe dehydration such as not urinating for a long time, has very cold or pale skin, has persistent vomiting, is extremely fussy or restless, or has a stiff neck.

Causes of Sepsis

Sepsis is caused by an infection that triggers an excessive body response, to the point that it starts to disrupt organ function. The infection can come from many parts of the body, not only the blood. However, it is important to understand: not every infection will develop into sepsis. Many infections can improve with appropriate treatment.

Sepsis calls for closer attention if an infection spreads, worsens, is not under control, or occurs in more vulnerable groups, such as older adults, babies, patients with chronic diseases, patients recovering from surgery, hospitalized patients, or people with weakened immune systems. Infections that lead to sepsis most often start in the digestive tract, lungs, skin, or urinary tract.

In general, some sources of infection that can trigger sepsis include:

• lung infections or pneumonia;
• urinary tract infections;
• skin or wound infections;
• digestive tract infections;
• infections after surgery or at the site of a medical procedure;
• bloodstream infections;
• infections in patients with weakened immune systems.

Lung Infections or Pneumonia

Pneumonia is an infection of the lungs and can be one of the serious sources of infection that trigger sepsis. In the early stages, the symptoms may look like an ordinary cough or fever. However, this condition calls for closer attention if lung symptoms are accompanied by signs that the whole body is starting to be affected.

Symptoms to watch for include:

• fever;
• a severe or worsening cough;
• shortness of breath;
• rapid breathing;
• extreme weakness;
• confusion or severe drowsiness, especially in older adults.

Pneumonia accompanied by rapid breathing, shortness of breath, a pounding heart, confusion, extreme weakness, or reduced urine output needs to be checked right away. In this situation, the problem is not only an infection in the lungs; the body may already be showing signs of a wider disturbance.

Urinary Tract Infections

Urinary tract infections can also cause sepsis in some patients, especially if the infection spreads, does not improve, or occurs in vulnerable groups. Early symptoms may include pain when urinating, frequent urination, lower abdominal pain, fever, or flank pain.

However, in older adults, the signs of a urinary tract infection can be nonspecific. Symptoms may include:

• sudden confusion or disorientation;
• extreme weakness;
• fever or chills;
• loss of appetite;
• reduced urine output;
• a chronic disease that suddenly worsens.

Avoid taking antibiotics on your own without a doctor’s guidance. Antibiotics are important for treating infections that can cause sepsis, but they need to be used appropriately because they can cause side effects and contribute to antimicrobial resistance.

Wound and Skin Infections

A worsening wound can become a source of infection and, in some cases, may trigger sepsis. This can happen with cuts, burns, surgical wounds, diabetic wounds, pressure sores, or skin infections that keep spreading.

Watch for the following warning signs:

• redness that keeps spreading;
• swelling;
• pus discharge;
• pain that keeps getting worse;
• fever or chills;
• skin around the wound that feels hot;
• a wound that turns black, smells bad, or shows dead tissue.

If a wound starts to turn black, smells bad, is very painful, or is accompanied by fever and extreme weakness, get it checked right away. In patients with diabetes or blood vessel disorders, wounds need to be monitored more carefully because healing may be slower and the risk of complications may be higher.

Digestive Tract Infections

Digestive tract infections can also be one of the sources of infection that trigger sepsis, especially if the symptoms are accompanied by severe dehydration or signs that the whole body is starting to weaken.

Pay attention if vomiting, diarrhea, or abdominal pain is accompanied by:

• high fever;
• extreme weakness;
• rapid breathing;
• reduced urine output;
• confusion or severe drowsiness;
• abdominal pain that keeps getting worse;
• a rapidly worsening condition.

In situations like this, what matters is not only how often the person vomits or has diarrhea. Also check whether the patient can still drink, is still urinating as usual, remains fully alert, and does not seem to be getting worse from hour to hour.

Infections After Surgery or a Hospital Stay

Patients who have recently had surgery, a medical procedure, a catheter inserted, or a hospital stay need to monitor for signs of infection more closely. This does not mean that every surgery or hospital stay will cause an infection. However, surgical wounds, IV sites, catheters, or certain medical devices are areas that need to be watched during recovery. Catheter sites, wounds, burns, ICU care, longer hospital stays, and medical devices inserted into the body can be factors linked to the risk of an infection developing into sepsis.

Consult a doctor right away if any of the following appear after surgery or a hospital stay:

• fever or chills;
• wound pain that keeps getting worse;
• a surgical wound that becomes redder, more swollen, filled with pus, smelly, or opens up;
• fluid leaking from the wound;
• extreme weakness;
• rapid breathing or shortness of breath;
• confusion;
• reduced urine output.

Infections in Patients With Weakened Immune Systems

Sepsis also calls for closer attention in people with weaker immune systems. This group can include cancer patients undergoing certain therapies, patients with HIV, patients taking immunosuppressive drugs, patients with certain chronic diseases, babies, and older adults.

In this group, an infection that seems mild at first can worsen more quickly, or its symptoms may not always be obvious. That is why changes such as fever, extreme weakness, rapid breathing, confusion, a fast heart rate, a worsening wound, or reduced urine output should be checked without delay.

Sepsis can be caused by infections in various parts of the body, especially if the infection spreads, worsens, or occurs in vulnerable groups. That is why you should pay attention not only to where the infection is, but also to changes in the body’s overall condition, including breathing, consciousness, heart rate, blood pressure, skin, and the amount of urine. Now that you understand the causes, the next section explains why sepsis can affect the heart and the circulatory system.

09 / Related Conditions

Why Can Sepsis Affect the Heart?

Sepsis is not a heart disease, but it can put a strain on the heart and the circulatory system. When the body faces a severe infection, the inflammatory response can affect the blood vessels, blood pressure, heart rate, and blood flow to the organs. As a result, some patients may experience signs such as a racing heart, a weak pulse, low blood pressure, shortness of breath, or extreme weakness.

This matters because blood carries oxygen and nutrients to vital organs, including the brain, kidneys, lungs, liver, and heart. If blood pressure drops or blood flow is disrupted, these organs may not get the supply they need. A high heart rate or a weak pulse, shortness of breath, and low blood pressure are findings a doctor may assess in a patient suspected of having sepsis. One of the goals of sepsis treatment is to maintain blood flow to the organs.

In sepsis, blood flow can be impaired so that vital organs do not receive the nutrients and oxygen they need. In more severe cases, sepsis can progress to a drastic drop in blood pressure, or septic shock. That is why symptoms such as a fast heart rate, low blood pressure, shortness of breath, extreme weakness, or reduced urine output should be seen as signs that the body may be experiencing a wider disturbance, not just a local infection.

Fast Heart Rate During Sepsis

A fast heart rate can be one of the body’s responses to a severe infection. When the body is fighting an infection, its need for oxygen and energy can increase. The heart then beats faster to help deliver blood to the body’s tissues.

However, a fast heart rate during an infection calls for closer attention if it appears together with other signs, such as:

• shortness of breath;
• extreme weakness;
• confusion or difficulty focusing;
• cold or clammy skin;
• a weak pulse;
• low blood pressure;
• reduced urine output.

In the context of sepsis, palpitations are not just a complaint that stands on its own. This sign needs to be seen together with the overall pattern of symptoms. If an infection is accompanied by rapid breathing, confusion, extreme weakness, a weak pulse, or a drop in blood pressure, the patient needs to be assessed by a medical professional right away.

Low Blood Pressure and Impaired Circulation

Blood pressure helps show whether blood flow to the organs is still adequate. If blood pressure drops too low, vital organs may not get enough blood and oxygen. This is why low blood pressure during a severe infection should not be taken lightly, especially when accompanied by severe dizziness, fainting, cold skin, a weak pulse, confusion, or very little urine.

In severe sepsis, the body can experience impaired circulation. This means blood flow and oxygen are no longer distributed properly to the body’s tissues. Even though the heart tries to work faster, the organs may still not get an adequate supply. Sepsis and septic shock are medical emergencies that require immediate assessment and treatment.

Risks for Patients With a History of Heart Disease

Patients with a history of heart disease need to be more watchful when they have a severe infection. This is not because every infection will cause heart problems, but because a heart that already has problems may have a more limited working reserve when the body faces major stress such as sepsis.

In some severe cases, sepsis may be linked to heart rhythm disorders or impaired heart function. However, this does not happen in every patient and must be assessed by a doctor based on the clinical condition, vital signs, physical examination, and supporting tests when needed. That is why you should avoid concluding on your own that heart symptoms during an infection must mean heart failure or cardiogenic shock.

Seek medical help right away if a patient with a history of heart disease has an infection accompanied by:

• shortness of breath;
• a racing heart;
• severe dizziness;
• fainting;
• chest pain;
• extreme weakness;
• cold or clammy skin;
• reduced urine output.

If you have a history of heart disease and have an infection accompanied by shortness of breath, a racing heart, severe dizziness, or extreme weakness, consult a medical professional about your condition right away.

Sepsis can put a strain on the heart and the circulatory system, especially when blood pressure drops, the heart rate rises, and the organs need adequate blood flow and oxygen. That is why symptoms such as a racing heart, shortness of breath, severe dizziness, fainting, confusion, or reduced urine output during an infection need to be checked right away, especially in patients with a history of heart disease. Now that you understand its effects on the heart and circulation, the next section covers who has a higher risk of sepsis.

Risk Factors for Sepsis

Anyone can develop sepsis, but some groups have higher risk factors for sepsis when they have an infection. This does not mean that every infection in these groups will develop into sepsis. However, a body that is more vulnerable may have more difficulty controlling an infection, so symptoms can worsen more quickly or be harder to recognize early on.

Anyone can develop sepsis, but some people are at higher risk, including adults aged 65 and older, children under 1 year old, people with chronic diseases such as diabetes or lung disease, people with weakened immune systems, pregnant or postpartum women, and patients who have recently had a serious illness, surgery, or a hospital stay.

Groups That Need to Be More Watchful

The following groups need to be more careful if they have an infection, fever, a worsening wound, shortness of breath, extreme weakness, confusion, or reduced urine output:

• Older adults, especially those aged 65 and older.
• Babies and young children, especially babies under 1 year old.
• Pregnant or postpartum women.
• People with diabetes.
• People with kidney disease, including patients with severe kidney impairment or on dialysis.
• People with chronic lung disease, such as chronic obstructive pulmonary disease or other long-term lung conditions.
• People with heart disease.
• Cancer patients or people with immune system disorders.
• Patients recovering from surgery.
• Patients who are currently or were recently hospitalized, including in the ICU.
• Patients with invasive medical devices, such as catheters, certain IV lines, ventilators, or other devices inserted into the body.

The WHO also states that groups vulnerable to sepsis include older adults, newborns, pregnant or postpartum women, hospitalized patients, ICU patients, people with weakened immune systems such as those with HIV or cancer, and people with chronic diseases such as kidney disease.

Why Do These Groups Need to Be More Careful?

There are several reasons why these groups need greater vigilance. First, the body may have more difficulty fighting infection, for example in cancer patients, people with immune disorders, or patients taking certain medications. Second, symptoms may be nonspecific, as in older adults who may not always develop a high fever. Third, infections may enter or develop more easily in certain situations, such as after surgery, during a hospital stay, or while using invasive medical devices.

In addition, chronic diseases can leave the body with a more limited “reserve” when facing a severe infection. For example, patients with diabetes, kidney disease, chronic lung disease, or heart disease may deteriorate more quickly if an infection is not treated promptly. Age over 65, infancy, weakened immunity, chronic diseases such as diabetes, kidney disease, or chronic obstructive pulmonary disease, ICU care or a long hospital stay, and the use of medical devices such as catheters and breathing tubes can be factors that may increase the risk of an infection developing into sepsis.

When Should You Seek Help Sooner?

If you or a family member belong to a more vulnerable group, do not just wait for an infection to “go away on its own” if worrying signs appear. Seek medical help right away if an infection is accompanied by:

• rapid breathing or shortness of breath;
• extreme weakness;
• confusion, severe drowsiness, or difficulty waking up;
• a very fast heart rate or a weak pulse;
• cold, pale, clammy, or sweaty skin;
• severe dizziness, fainting, or low blood pressure;
• very little urine;
• a wound that becomes redder, more swollen, filled with pus, smelly, or blackened;
• a chronic disease that is worsening quickly.

A Note for Patients With Heart Disease

Patients with heart disease need to be more watchful when they have a severe infection. An infection can make the body need more oxygen, while the heart has to work harder to help maintain blood flow. If an infection is accompanied by shortness of breath, a racing heart, severe dizziness, chest pain, fainting, or extreme weakness, the condition should be checked right away.

This does not mean that every heart patient with an infection will develop sepsis. However, being watchful earlier helps the doctor assess whether the infection is still mild, is starting to worsen, or is already affecting circulation and organ function.

Sepsis risk factors help families recognize who needs to be checked sooner when they have an infection. Older adults, babies and young children, pregnant or postpartum women, patients with chronic diseases, patients with weakened immune systems, patients recovering from surgery, hospitalized patients, and patients with invasive medical devices need extra attention when signs of infection appear. Now that you understand who is at higher risk, the next section explains how doctors diagnose sepsis by assessing symptoms, vital signs, the source of infection, and organ function.

How Do Doctors Diagnose Sepsis?

Diagnosing sepsis requires a thorough assessment by medical professionals. Doctors do not look at just one symptom, one lab value, or one test result. The doctor will assess whether there is an infection or a suspected infection accompanied by signs that the body is starting to be affected, such as rapid breathing, an increased heart rate, low blood pressure, changes in consciousness, reduced urine output, or signs of organ dysfunction.

This matters because sepsis symptoms can resemble those of other severe infections. That is why a diagnosis needs to combine the history of symptoms, physical examination, vital signs, medical history, the possible source of infection, and supporting test results when needed. Sepsis is a clinical diagnosis and should not be confirmed or ruled out based on a single biomarker or a single diagnostic test.

In general, doctors may assess the following:

• Vital signs: blood pressure, heart rate, breathing rate, body temperature, and oxygen saturation.
• General condition: consciousness, extreme weakness, skin color, severe pain, and signs of impaired circulation.
• Urine output: very little urine may indicate that the body is not getting enough blood flow or that the organs are starting to be affected.
• Possible source of infection: the lungs, urinary tract, wounds, skin, digestive tract, surgical site, or certain medical devices.
• Blood tests: to assess signs of infection, organ function, blood clotting, electrolytes, and oxygen levels.
• Blood cultures when needed: to help find the germ causing the infection.
• Urine tests or tests of other samples: depending on the suspected source of infection.
• Kidney and liver function: to see whether the organs are starting to be affected.
• Heart tests when indicated: for example if there are palpitations, a drop in blood pressure, shortness of breath, chest pain, or a history of heart disease.

Sepsis is diagnosed through a medical assessment by healthcare professionals, including physical findings such as fever, an increased heart rate, low blood pressure, and difficulty breathing. Doctors may run tests to look for signs of infection or organ damage, including blood cultures or other tests to identify the cause of the infection.

Checking Vital Signs and General Condition

The first step in assessing sepsis is to see whether the patient’s condition is still stable. Doctors and medical staff usually assess:

• blood pressure;
• pulse or heart rate;
• breathing rate;
• body temperature;
• oxygen saturation;
• level of consciousness.

Vital signs help doctors understand whether the body is still able to maintain circulation and oxygenation properly. For example, low blood pressure may indicate that blood flow to the organs is starting to be disrupted. Rapid breathing may be a sign that the body is short of oxygen or under severe stress from an infection. A very fast heart rate may also indicate that the body is trying to maintain blood flow.

In addition, the doctor will look at the patient’s general condition. Does the patient look extremely weak? Is the patient starting to become confused? Does the skin look cold, pale, or clammy? Is there very little urine?

Blood Tests and the Source of Infection

Blood tests can help doctors assess two main things: whether there are signs of infection and whether the organs are starting to be affected. Blood tests can be used to look for signs of infection, blood clotting problems, impaired kidney or liver function, oxygen levels lower than the body needs, and electrolyte imbalances.

Doctors may also order blood cultures when needed. A culture helps identify the germ causing the infection, so treatment can be adjusted once the results are available. Drawing blood cultures as soon as possible is recommended for adult patients with possible sepsis or septic shock, ideally before antimicrobials are given when the situation allows.

However, the source of infection is not always the blood. That is why doctors may order other tests depending on the suspected source of infection, such as:

• urine tests, if a urinary tract infection is suspected;
• tests of fluid from a wound, if a wound is filled with pus or getting worse;
• tests of sputum or mucus from the airways, if a lung infection is suspected;
• imaging tests, such as an X-ray, ultrasound, CT scan, or MRI if the source of infection is not yet clear.

Doctors may order several tests to look for the infection underlying sepsis, including blood tests, urine samples, fluid from wounds, mucus or sputum from the airways, and imaging tests if the site of infection is not easy to find.

Heart Evaluation When Needed

In some patients, sepsis can be accompanied by signs related to the cardiovascular system, such as a racing heart, a weak pulse, low blood pressure, shortness of breath, severe dizziness, or fainting. If the patient also has a history of heart disease, the doctor may consider a cardiovascular evaluation as part of the overall assessment.

Tests that may be considered depending on the patient’s condition include:

• ECG, to look at the heart’s electrical activity and rhythm;
• heart rhythm monitoring, especially if the heart rate is very fast or irregular, or the patient appears unstable;
• heart function tests, if the doctor finds signs of impaired heart function or circulation.

Heart tests are not always needed for every patient with sepsis. However, this evaluation can be important if there is chest pain, severe shortness of breath, a drop in blood pressure, unusual palpitations, or a history of heart disease. Patients with sepsis may need close monitoring and care in the hospital because some patients require interventions to stabilize their breathing and heart function.

How Is Sepsis Treated?

Sepsis is treated with prompt medical assessment, therapy to control the infection, and support to maintain blood flow and organ function. Treatment must be carried out by medical professionals because the patient’s condition can change quickly, especially if the infection is accompanied by rapid breathing, confusion, low blood pressure, a fast heart rate, extreme weakness, or reduced urine output.

Prompt and effective sepsis treatment includes giving appropriate therapy, including antibiotics when needed, as well as efforts to maintain blood flow to the organs. In some cases, medical procedures or surgery may also be needed to remove tissue damaged by the infection.

In general, sepsis treatment may include:

• Rapid assessment to evaluate vital signs, consciousness, breathing, blood pressure, the source of infection, and organ function.
• Antibiotics, if the doctor suspects a bacterial infection.
• Intravenous (IV) fluids, if the patient needs fluid and circulatory support.
• Oxygen, if oxygen levels are low or the patient is short of breath.
• Medications to support blood pressure, especially in severe cases where blood pressure stays low.
• Treating the source of infection, for example wound care, draining pus, or other procedures depending on the cause.
• Monitoring organ function, such as the kidneys, liver, lungs, heart, blood clotting, and urine output.
• Intensive care, if severe sepsis or septic shock develops.

Rapid Assessment and Close Monitoring

The first step in treating sepsis is to assess whether the patient’s condition is still stable. The medical team will check blood pressure, pulse, breathing rate, body temperature, oxygen saturation, level of consciousness, urine output, and signs of impaired circulation.

This monitoring matters because the patient’s condition can change over time. For example, blood pressure may drop, breathing may become more labored, or urine output may decrease if blood flow to the organs is not adequate. Based on this assessment, the doctor decides whether the patient needs IV fluids, oxygen, blood pressure medication, additional tests, or more intensive care.

Antibiotics When a Bacterial Infection Is Suspected

If the doctor suspects that sepsis is caused by a bacterial infection, antibiotics may be given as soon as possible depending on the patient’s condition. At the start of treatment, the doctor may use antibiotics that cover many possible germs, then adjust them once test results show the cause of the infection more clearly. In sepsis, antibiotics are started as soon as possible and can be adjusted once blood test results are available.

However, antibiotics should not be taken on your own without a doctor’s guidance. Antibiotics are very important for treating infections that can cause sepsis, but they must be used appropriately because they can cause side effects and contribute to antimicrobial resistance.

IV Fluids, Oxygen, and Blood Pressure Support

In some patients, sepsis can cause blood pressure to drop or circulation to be disrupted. In this situation, the doctor may give IV fluids to help maintain fluid volume and blood flow.

In addition, patients may be given oxygen if their oxygen saturation is low, they are short of breath, or they appear to be having difficulty breathing. If blood pressure remains too low after initial therapy, the doctor may use special medications to help raise blood pressure. These medications are given under close medical supervision, especially in patients with severe sepsis or septic shock.

Intravenous fluids, vasopressors to help raise blood pressure, oxygen, breathing support, and dialysis if kidney function is impaired may be part of supportive care for patients with sepsis, depending on clinical need.

Treating the Source of Infection

Sepsis treatment does not focus only on stabilizing the body’s condition. Doctors also need to find and treat the source of infection. The source may be the lungs, urinary tract, a wound, an abscess, infected tissue, a catheter site, or a surgical wound.

If there is a source of infection that needs to be treated directly, the doctor may perform procedures such as:

• draining pus;
• wound care;
• removing dead tissue;
• replacing or removing certain medical devices;
• surgery depending on the patient’s condition.

Surgery may be needed to remove the source of infection, such as a collection of pus, infected tissue, or dead tissue.

Monitoring Organ Function

Because sepsis can affect many organs, doctors will monitor the body’s functions as a whole. Tests may include kidney, liver, lung, and heart function, blood clotting, oxygen levels, blood sugar levels, fluid balance, and urine output.

This monitoring helps doctors see whether treatment is working well or needs to be adjusted. For example, very little urine may indicate reduced blood flow to the kidneys. Shortness of breath or low oxygen saturation may indicate breathing problems. Low blood pressure may signal that circulation is not yet stable.

Intensive Care for Severe Sepsis or Septic Shock

In severe sepsis or septic shock, patients may need intensive care. The goal is to monitor the condition closely, maintain blood pressure, support breathing, maintain blood flow to the organs, and adjust treatment based on the patient’s response.

Intensive care does not mean the patient will not recover. However, in the severe phase, the body needs closer monitoring because changes in blood pressure, oxygen, kidney function, consciousness, and heart rate can happen quickly.

Complications of Sepsis

Complications of sepsis can involve many organs, especially in severe cases or when treatment is delayed. However, these complications do not occur in every patient. Many patients can improve, especially if sepsis is recognized early and treated quickly by medical professionals.

Sepsis needs to be taken seriously because the body’s response to an infection can disrupt blood flow, blood pressure, oxygenation, and organ function. Without prompt treatment, sepsis can progress to tissue damage, organ failure, and even death. In addition, sepsis can cause shock and multiple organ failure if it is not recognized and treated immediately.

Complications That Can Occur in Severe Cases

In severe cases, complications of sepsis may include:

• Septic shock, a condition in which blood pressure drops very low and circulation is seriously disrupted.
• Acute kidney injury, when the kidneys start to have difficulty filtering fluid and waste products.
• Breathing problems, such as severe shortness of breath, rapid breathing, or falling oxygen levels.
• Impaired heart function, especially when blood pressure drops, circulation is disrupted, or the heart has to work harder.
• Heart rhythm disorders, which may occur in some patients with severe sepsis or a vulnerable heart condition.
• Blood clotting disorders, which can trigger small blood clots or a risk of bleeding in certain conditions.
• Altered consciousness, such as confusion, severe drowsiness, difficulty focusing, or decreased consciousness.
• A longer recovery, because the body needs time to recover after a severe infection.

Why Can Sepsis Affect Many Organs?

The body’s organs need a steady supply of blood and oxygen to work properly. In severe sepsis, the inflammatory response can disrupt the blood vessels, blood pressure, and the distribution of blood flow. As a result, some organs may receive less oxygen than they need.

That is why the complications of sepsis can look different in each patient. In some patients, the main problem appears in their breathing. In others, urine output falls because the kidneys are affected. Some patients also seem confused because the brain is not getting enough oxygen and circulatory support.

If the patient has a history of heart disease, diabetes, kidney disease, lung disease, or a weakened immune system, the doctor will usually monitor organ function more closely.

Septic Shock

Septic shock is one of the most serious complications of sepsis. This condition can occur when blood pressure drops very low and the body struggles to maintain blood flow to the organs. As a result, vital organs may not get enough oxygen and nutrients.

Signs to watch for include:

• very low blood pressure;
• fainting or nearly fainting;
• a weak pulse;
• cold, pale, or clammy skin;
• rapid breathing or shortness of breath;
• very little urine;
• decreased consciousness.

Septic shock occurs when blood pressure drops drastically and does not improve with IV fluids alone. Sepsis can progress to shock and multiple organ failure if it is not treated in time.

Acute Kidney Injury

In some patients, sepsis can cause acute kidney injury. This can happen when the kidneys do not get enough blood flow or are affected by the severe inflammation caused by the infection.

Signs that may appear include:

• much less urine than usual;
• increasing weakness;
• swelling in certain parts of the body;
• worsening kidney function test results.

Very little urine is an important sign because it may indicate that blood flow to the kidneys is disrupted or that organ function is starting to decline. Sepsis can cause kidney damage and even acute kidney failure in some cases.

Breathing Problems

Sepsis can also affect the respiratory system. In severe cases, patients may experience shortness of breath, rapid breathing, falling oxygen levels, or a need for oxygen support.

Breathing problems can occur because the initial infection started in the lungs, as in pneumonia, or because sepsis affects how the whole body functions.

Impaired Heart Function and Heart Rhythm Disorders

Sepsis is not a heart disease. However, in severe cases, this condition can put a strain on the heart and the circulatory system. When blood pressure drops, the body needs more oxygen, and the organs start to be affected, the heart may work harder to help maintain blood flow.

In some patients, especially those with a history of heart disease or a very severe overall condition, sepsis may be linked to impaired heart function or heart rhythm disorders. However, this does not happen in every patient and needs to be assessed by a doctor through clinical examination and supporting tests when needed. As sepsis worsens, vital organs, including the heart, may not get enough blood flow. The Indonesian Ministry of Health (Kemenkes RI) also lists heart problems as one of the complications that can occur.

Blood Clotting Disorders

In severe sepsis, the blood clotting process can also be disrupted. In some patients, the body may form small clots in the blood vessels. In other situations, the blood’s ability to clot may also be impaired, increasing the risk of bleeding.

Sepsis can cause abnormal blood clotting; small clots or damaged blood vessels can disrupt tissues. The Indonesian Ministry of Health also lists blood clotting disorders as a complication that can occur in sepsis.

Altered Consciousness and a Longer Recovery

Sepsis can affect the brain and nervous system, especially when blood flow, oxygen, or organ function is disrupted. In some patients, this may appear as confusion, difficulty focusing, severe drowsiness, or decreased consciousness.

After the acute phase has passed, recovery can also take time. Some sepsis survivors may experience symptoms after going home, such as extreme weakness, tiring easily, shortness of breath, body aches, difficulty moving, sleep problems, reduced appetite, anxiety, difficulty concentrating, or emotional changes. That is why recovery should be gradual and follow the guidance of healthcare professionals.

How to Prevent Sepsis

Preventing sepsis starts with preventing infections, treating infections early, and seeking medical help right away if an infection seems to be getting worse. Sepsis cannot always be fully prevented, but the risk can be lowered through good hygiene, vaccination as recommended by a doctor, proper wound care, managing chronic diseases, and using antibiotics appropriately. Sepsis prevention focuses on two main steps: preventing infections from occurring and preventing infections from developing into sepsis.

These preventive steps are important for everyone. However, greater vigilance is needed for older adults, babies and young children, pregnant or postpartum women, patients with diabetes, kidney disease, lung disease, or heart disease, patients recovering from surgery, and people with weakened immune systems. The CDC (Centers for Disease Control and Prevention) emphasizes four main ways to lower the risk of sepsis: preventing infections, keeping clean, knowing the signs and symptoms, and acting fast.

Keeping Your Hands Clean

Keeping your hands clean is a simple step that can help prevent many infections. Hands often carry germs from the environment to the mouth, nose, eyes, food, wounds, or other people.

Make it a habit to wash your hands:

1. before eating or preparing food;
2. after using the toilet;
3. after coughing, sneezing, or blowing your nose;
4. before and after caring for a wound;
5. before touching a baby, an older adult, or someone who is sick;
6. after coming home from public places or healthcare facilities.

In addition, keep your food, drinking water, and surroundings clean. Personal hygiene, safe food, good sanitation, and access to clean water are important parts of preventing infections that can lead to sepsis.

Caring for Wounds Properly

Even small wounds need proper care, especially in patients with diabetes, blood vessel disorders, older adults, or people with weakened immune systems. A wound that is not cleaned or is left to get worse can become an entry point for germs.

Have a wound checked by a doctor if signs such as these appear:

• redness that keeps spreading;
• swelling;
• increasing pain;
• pus discharge;
• a bad-smelling wound;
• skin around the wound that feels hot;
• fever or chills;
• a wound that turns black or shows dead tissue.

The CDC advises keeping cuts and wounds clean and covered until they heal, as part of preventing infections that can develop into sepsis.

Not Delaying a Checkup When an Infection Gets Worse

Not every infection will become sepsis. However, an infection that worsens quickly needs to be checked right away, especially if signs appear that the whole body is starting to be affected.

Seek medical help right away if an infection is accompanied by:

• rapid breathing or shortness of breath;
• extreme weakness;
• confusion, severe drowsiness, or difficulty waking up;
• a very fast heart rate;
• cold, pale, or clammy skin;
• low blood pressure, severe dizziness, or fainting;
• very little urine;
• severe pain;
• a rapidly worsening condition.

At this point, the recommended step is not to wait, but to get a medical assessment. It is very important to recognize the signs of sepsis and act quickly to lower the risk of deterioration.

Getting Vaccinated as Recommended by Your Doctor

Vaccination can help prevent or reduce the severity of some infections that can trigger sepsis. The vaccines a person needs can differ, depending on age, medical history, pregnancy, immune status, occupation, travel, and the doctor’s recommendation.

That is why you should discuss your vaccination schedule with a healthcare professional, especially if you or a family member belong to a more vulnerable group. Vaccination is an important step in reducing the risk of infections that can develop into sepsis.

Keeping Chronic Diseases Under Control

Uncontrolled chronic diseases can make the body more vulnerable to infection or slower to recover when an infection occurs. That is why patients with diabetes, kidney disease, chronic lung disease, heart disease, cancer, or immune disorders need to manage their health consistently.

Steps that may help include:

1. regular checkups as recommended by your doctor;
2. taking medications as prescribed;
3. monitoring blood sugar, blood pressure, or other chronic conditions as directed by your doctor;
4. not delaying a checkup if fever, a worsening wound, shortness of breath, or extreme weakness appears;
5. telling your doctor about any unusual changes in your condition.

Managing chronic diseases such as diabetes, lung disease, cancer, and kidney disease is part of the strategy for preventing infections that can cause sepsis.

Using Antibiotics as Directed by Your Doctor

Antibiotics can be an important treatment when an infection is caused, or suspected to be caused, by bacteria. However, antibiotics should not be used carelessly, bought on your own without an examination, stopped without a doctor’s guidance, or taken from someone else’s leftover medication.

Inappropriate use of antibiotics can cause side effects and contribute to antimicrobial resistance, a condition in which germs become harder to treat. Antimicrobial resistance is a factor that can affect the success of treatment and speed up progression to sepsis or septic shock.

Use antibiotics only as directed by your doctor, including the type, dose, schedule, and duration. If your symptoms do not improve or get worse while taking the medication, consult your doctor again right away.

Monitoring Symptoms After Surgery or a Hospital Stay

Patients who have recently had surgery, a medical procedure, a catheter inserted, or a hospital stay need to watch for signs of infection during recovery. This does not mean that every medical procedure will cause an infection. However, surgical wounds, IV sites, catheters, or certain medical devices do need to be monitored more carefully.

Contact a medical professional right away if any of the following appear after surgery or a hospital stay:

• fever or chills;
• a wound that becomes redder, more swollen, painful, filled with pus, smelly, or opens up;
• fluid leaking from the wound;
• extreme weakness;
• rapid breathing or shortness of breath;
• confusion;
• reduced urine output;
• a rapidly worsening condition.

Preventing sepsis in healthcare facilities is linked to infection prevention and control programs, effective hygiene practices, and clean, properly functioning equipment. For patients and families, the practical step is to monitor changes after treatment and report promptly if signs of infection or deterioration appear.

When Should You See a Doctor or Go to the ER?

When dealing with an infection, the most important question is: “Can this still wait for a doctor’s appointment, or do we need to go to the ER right away?” Not every fever, cough, wound, or urinary tract infection means sepsis. However, if an infection is accompanied by changes in breathing, consciousness, blood pressure, heart rate, the amount of urine, or a rapidly worsening condition, the recommended step is to seek medical help right away.

Sepsis is a medical emergency. Signs to watch for may include fever or a low body temperature, chills, confusion, difficulty breathing, clammy skin, severe pain, a high heart rate, a weak pulse or low blood pressure, and low urine output. An infection that does not improve or keeps getting worse needs to be assessed by a healthcare professional right away, because patients who may have sepsis must be evaluated and treated promptly.

Go to the ER Right Away If Warning Signs Appear

Take the patient to the ER right away if an infection is accompanied by one or more of the following signs:

• Confusion, sudden disorientation, speaking incoherently, severe drowsiness, or difficulty communicating.
• Rapid breathing or shortness of breath, especially if the patient appears to be working hard to breathe.
• Fainting, nearly fainting, or looking extremely weak.
• A drop in blood pressure, a weak pulse, severe dizziness, or skin that feels cold.
• Very little urine, for example urinating much less often than usual.
• Cold, pale, clammy, sweaty, or bluish-looking skin.
• Rapidly worsening condition, even if it initially looked like an ordinary infection.
• Severe pain or unusual discomfort.
• In children: difficulty waking up, sleeping all the time, refusing to drink or breastfeed, rapid breathing, seizures, very cold or pale skin, or not urinating for a long time.

For children, IDAI advises going to the ER or a hospital right away if the child has seizures, sleeps continuously and is hard to wake, has shortness of breath with chest indrawing, shows signs of severe dehydration such as not urinating for a long time, has very cold or pale skin, has persistent vomiting, or has other severe symptoms.

In situations like these, do not wait for every symptom to appear. Sepsis can progress quickly, and an early examination helps the doctor assess whether the infection has started to disrupt circulation, blood pressure, breathing, consciousness, or organ function.

See a Doctor If an Infection Is Not Improving

Not every infection needs to go straight to the ER. However, seeing a doctor is still important if an infection does not improve, keeps coming back, or occurs in a more vulnerable patient.

Schedule a doctor’s visit soon if you have:

• A fever that does not improve, keeps coming back, or comes with increasing weakness.
• A wound that becomes redder, swollen, filled with pus, smelly, or more painful.
• Recurring infections, for example urinary tract, skin, or respiratory infections that keep coming back.
• A chronic disease plus symptoms of infection, such as diabetes, kidney disease, lung disease, heart disease, cancer, or an immune disorder.
• After surgery, fever, worsening pain, changes in the wound, or fluid leaking from the wound.
• A history of heart disease, and after an infection, palpitations, shortness of breath, chest pain, severe dizziness, or extreme weakness appear.

People with chronic diseases, weakened immune systems, older age, babies, pregnant or postpartum women, and patients who have recently had a serious illness, surgery, or a hospital stay are at higher risk of sepsis. That is why these groups should not delay a checkup if an infection starts to get worse or the symptoms feel unusual.

How to Make a Calmer Decision

If you are still unsure, use the following simple guide:

Condition	Recommended Step
Infection with confusion, rapid breathing, shortness of breath, fainting, a drop in blood pressure, cold/pale skin, very little urine, or a rapidly worsening condition	Go to the ER right away
A child who is hard to wake, refuses to drink/breastfeed, has seizures, shortness of breath, very cold/pale skin, or has not urinated for a long time	Go to the ER right away
A fever that does not improve, a wound that is getting redder/swollen/filled with pus, recurring infections, or symptoms appearing after surgery	See a doctor
The patient has a chronic disease or a history of heart disease and the infection seems to be getting worse	See a doctor sooner; go to the ER if warning signs appear
Symptoms seem severe and the family is considering taking antibiotics without a prescription	Do not self-medicate; get an assessment from a medical professional

Conclusion

Sepsis is a medical emergency that needs to be recognized early. This condition occurs when the body’s response to an infection becomes excessive, to the point that it starts to disrupt organ function. Not every infection will develop into sepsis. However, an infection accompanied by rapid breathing, confusion, extreme weakness, a fast heart rate, low blood pressure, cold or clammy skin, severe pain, or reduced urine output needs to be checked by a medical professional right away.

Sepsis can cause organ dysfunction, shock, and multiple organ failure if it is not recognized and treated quickly. Sepsis is a medical emergency that can quickly progress to tissue damage and organ failure without prompt treatment. That is why you should not wait until all the symptoms appear or until the condition looks very severe.

In the context of heart health, sepsis is not a heart disease. However, this condition can affect circulation, blood pressure, heart rate, and organ function. When blood pressure drops or blood flow is disrupted, vital organs need an adequate supply of oxygen and blood. In some patients, especially those with a history of heart disease, this condition can make the heart work harder.

Some groups need to be more watchful when they have an infection, including:

1. older adults;
2. babies and young children;
3. pregnant or postpartum women;
4. patients with diabetes, kidney disease, lung disease, or heart disease;
5. cancer patients or people with immune disorders;
6. patients recovering from surgery, hospitalized patients, ICU patients, or people using invasive medical devices.

Very young or older age, pregnancy or the period after giving birth, chronic diseases, immune disorders, and a history of hospital stays or medical procedures are factors that can increase the risk of sepsis.

The most important message is simple: recognize the pattern, not just a single symptom. An infection that seems ordinary calls for closer attention if it is accompanied by rapid breathing, confusion, a drop in blood pressure, a racing heart, fainting, very little urine, or a rapidly worsening condition. In children, signs such as being hard to wake, refusing to drink or breastfeed, pale or cold skin, and seizures also need to be checked right away.

At Heartology Cardiovascular Hospital, cardiologists can help evaluate heart symptoms, rhythm disorders, shortness of breath, or cardiovascular conditions after a severe infection. For emergencies, the Heartology emergency department (ER) operates 24 hours a day, every day, and 1500 258 is available as the cardiac emergency number.
