Prehypertension: Understanding the Early Stage of High Blood Pressure

Blood pressure in the range of 120 to 139/80 to 89 mmHg may be a sign of prehypertension; have it confirmed through a doctor’s examination.

Starting the day by checking your blood pressure is now a habit for many people, whether using a digital device at home, getting a quick check at a clinic, or during an annual medical check-up (MCU). Awareness of heart health in Indonesia continues to grow, especially after various national campaigns emphasized the importance of early detection of cardiovascular disease. The Indonesian Ministry of Health (Kemenkes) also emphasizes that routine blood pressure checks are a key step in preventing long-term complications.

However, blood pressure numbers that are starting to rise almost never cause symptoms. In fact, most people do not feel any complaints and only notice the change when they see their blood pressure reading. In addition, some people only check their blood pressure when they feel dizzy or tired, so small changes that happen from day to day are often missed.

A Slight Rise in Blood Pressure Can Be an Early Signal

In fact, a rise in blood pressure of even a few points can be a sign that the heart and blood vessels are working harder. And even though the body seems fine, the cardiovascular system may actually be under a heavier load. Many people only find out about this condition after their readings show values at the upper limit of the normal category, often referred to as “borderline” blood pressure.

In addition, recommendations from international organizations such as the American Heart Association (AHA) emphasize that small changes in blood pressure are already reason enough to assess your risk early.

The Good News: Borderline Blood Pressure Is Not a Life Sentence

Even so, borderline blood pressure is not a life sentence or something to be afraid of. Instead, it is a good opportunity to take preventive steps before your blood pressure develops into hypertension. With a healthier diet, regular physical activity, stress management, and the right heart health screening, this condition can be controlled and can even return to the normal category.

Next, understanding what is actually happening in your body, and recognizing the blood pressure categories to watch out for, are important steps in preventing hypertension in the future. In the next section, we will discuss clearly and simply: What Is Prehypertension?

01 / Heart Disease

What Is Prehypertension?

Prehypertension is a condition in which blood pressure is above the normal limit, namely a systolic pressure of 120 to 139 mmHg or a diastolic pressure of 80 to 89 mmHg. This range is a category widely used in the medical literature, including international scientific reviews on borderline blood pressure.

Prehypertension as a “Yellow Zone”: Not Yet Hypertension, but Past the Safe Limit

Prehypertension is often described as a yellow zone, a stage in which blood pressure is no longer entirely safe but has not yet reached the hypertension stage.

In fact, blood pressure values in this range show that:

• The heart is starting to work harder than it ideally should.
• The blood vessels are starting to receive higher pressure than usual.
• The risk of progressing to hypertension increases, especially if your lifestyle does not support heart health.

In addition, prehypertension often causes no symptoms at all. That is why many people only find out about their condition after a routine blood pressure measurement, such as during an MCU.

This Condition Is Reversible: A Chance to Act Early

The good news is that prehypertension can be reversible. In other words, this condition can return to the normal limit if it is addressed early. Cardiology organizations such as PERKI (Indonesian Heart Association) encourage early intervention through:

• A low-salt diet,
• Regular physical activity,
• Stress management,
• Weight control, and
• Regular blood pressure checks.

Several studies also show that lifestyle changes at the prehypertension stage can delay or prevent progression to hypertension.

By understanding where you stand in the blood pressure range, you can take effective preventive steps. Next, let’s take a closer look at how to tell normal blood pressure, prehypertension, and hypertension apart, and what each category means for your heart health.

02 / Heart Disease

Blood Pressure Ranges: Normal vs Prehypertension vs Hypertension

Understanding blood pressure ranges helps you know where your health stands right now, whether you are still in the normal category, have entered prehypertension, or have already developed hypertension. These categories refer to guidelines from credible organizations such as the American Heart Association (AHA) and the European Society of Cardiology (ESC), which are widely used in clinical practice around the world.

Blood Pressure Category Table

Category	Systolic (mmHg)	Diastolic (mmHg)	What It Means for Your Health
Normal	<120	<80	Safe zone. The heart works efficiently and the blood vessels are in healthy condition.
Prehypertension	120 to 139	80 to 89	Yellow zone. Blood pressure is starting to rise and puts extra strain on the heart.
Hypertension	≥140	≥90	High-risk zone. A medical evaluation is needed because the risk of complications increases.

Reference source: American Heart Association

Normal Blood Pressure (<120/<80 mmHg)

Normal blood pressure is below 120/80 mmHg. In this condition:

• The heart pumps blood optimally.
• The blood vessels work within a healthy capacity.
• The risk of heart disease and stroke is at its lowest point.

Staying in the normal category is very important.

In addition, a healthy lifestyle such as a low salt intake, regular exercise, enough sleep, and stress management has been shown to help keep blood pressure stable.

Prehypertension (120 to 139 / 80 to 89 mmHg)

Prehypertension is in the systolic range of 120 to 139 mmHg or the diastolic range of 80 to 89 mmHg.

Although it may look like a small change, these numbers have a big impact on long-term health.

Why is this change significant?

• The blood vessels are starting to receive higher pressure than usual.
• The heart works harder, even though it causes no symptoms.
• The risk of progressing to hypertension increases gradually.

On top of that, a rise in blood pressure within a range that seems “slight” can multiply the risk of heart disease and stroke when it is not managed well.

This is the right moment for prevention. Regular checkups and consistent lifestyle changes are often enough to keep this condition from progressing.

Hypertension (≥140/90 mmHg)

Hypertension is diagnosed when blood pressure reaches ≥140/90 mmHg. At this stage:

• The risk of complications increases significantly.
• The load on the heart and blood vessels is heavier.
• The risk of coronary heart disease, heart failure, stroke, and kidney disease rises sharply.

Uncontrolled hypertension contributes directly to serious cardiovascular events. That is why this condition requires medical monitoring, lifestyle intervention, and, if needed, medication.

Once you understand the difference between normal blood pressure, prehypertension, and hypertension, the next step is to recognize the signs or body signals that may appear when blood pressure starts to rise.

03 / Heart Disease

Characteristics and Body Signals of Prehypertension

Prehypertension is often called a “silent” condition because it does not show clear signs in most people. Blood pressure in the range of 120 to 139/80 to 89 mmHg usually does not yet cause noticeable symptoms, but it still points to important changes that need attention.

This is why it is important to understand your body’s signals, even though they are often vague. In addition, routine blood pressure monitoring is the key step in detecting prehypertension as early as possible and preventing it from progressing to hypertension.

1. Often There Are No Symptoms at All

Most patients with prehypertension are not aware of their condition because the body is still able to adapt to the rise in blood pressure. A gradual increase in blood pressure usually does not cause pain or physical changes that are easy to recognize.

In other words, the absence of symptoms does not mean your blood pressure is fine. In fact, this is the main reason why routine blood pressure checks are so necessary, especially if you have risk factors.

2. Indirect Signs to Watch For

Although it often has no symptoms, some people with prehypertension may experience indirect signs. Although they are not specific, the following signals may indicate that the body is working harder:

• Frequent mild dizziness: Mild dizziness can appear especially after standing up too quickly, during stress, or when tired. This sensation occurs because of changes in the pressure of blood flow to the brain.
• Tiring easily: When blood pressure starts to rise, the heart needs to work harder to pump blood throughout the body. As a result, the body feels tired more quickly even when activities are not very strenuous.
• Heart palpitations in certain situations: Sudden palpitations, for example during stress or anxiety or after consuming caffeine, can occur as a nervous system response to rising blood pressure.
• Headaches at certain times: Mild headaches, especially in the morning or after intense activity, sometimes appear. However, headaches are not a main symptom of slightly elevated blood pressure.

Important note:

These symptoms can appear in many other conditions. That is why, if you often experience these signs, check your blood pressure to determine the cause.

3. Why Don’t Symptoms Always Appear?

There are several scientific explanations for why prehypertension rarely shows clear signs:

• The blood vessels are able to adapt : In the early phase, the blood vessels can still widen (vasodilation) to adjust to the increased pressure, so no discomfort is felt.
• Blood pressure rises gradually : Because the process is slow, the body does not send sudden signals. This gradual adaptation is what often causes the condition to be overlooked.
• The nervous system does not always trigger pain: A rise in blood pressure does not directly stimulate pain nerves, unlike conditions such as a heart attack or migraine.

That is why prehypertension remains risky even if you do not feel anything. Monitoring your blood pressure with a calibrated device or through routine screening is strongly recommended.

Why Is Checking Your Blood Pressure So Important?

Routine blood pressure checks help you:

• Find out whether you have entered the prehypertension phase
• Monitor whether your blood pressure is improving or rising instead
• Prevent progression to hypertension
• Reduce the risk of serious complications such as stroke and heart disease

These checks help detect risks early, especially for people with a family history of hypertension, obesity, or a high-stress life.

04 / Heart Disease

Causes and Risk Factors of Prehypertension

Prehypertension can arise from a combination of lifestyle factors, biological conditions, and long-term habits. Understanding these risk factors is very important, because every small change in blood pressure can develop into hypertension if left unchecked. On the other hand, knowing the causes helps you take preventive steps sooner.

According to the American Heart Association (AHA) and the European Society of Cardiology (ESC), most cases of prehypertension are influenced by lifestyle and internal factors that make the body work harder to maintain normal blood pressure.

1. Lifestyle Factors That Increase the Risk of Prehypertension

Lifestyle factors are the most common cause of prehypertension. Many patients only become aware of their condition after a routine checkup.

• High salt intake : Too much salt makes the body retain fluid, which increases blood volume and raises pressure. WHO recommends an intake of <5 grams/day, but salt intake in Indonesia is generally far above this limit.
• Lack of physical activity : Not moving enough keeps the heart from working as efficiently as it should. Regular activity can lower systolic blood pressure by 5 to 8 mmHg, a fairly significant amount for preventing prehypertension.
• Excess body weight : Excess weight increases insulin resistance and makes the blood vessels stiffer. This makes blood pressure rise more easily.
• Excessive alcohol consumption : Alcohol can raise blood pressure because it affects the heart rate, liver function, and the body’s fluid balance.
• Smoking : Nicotine causes the blood vessels to narrow quickly, so blood pressure rises right away. Even passive smokers have a higher risk of prehypertension.

2. Internal Factors That Contribute to Prehypertension

Some people develop prehypertension even though they already lead a healthy lifestyle. This happens because certain biological factors also play a role.

• Family history : If a parent or sibling has hypertension, your chance of developing prehypertension is higher.
• Insulin resistance : This condition, which is linked to obesity and prediabetes, affects how the blood vessels respond to pressure, so blood pressure rises more easily.
• Chronic stress : Long-term stress triggers the release of hormones such as cortisol and adrenaline, which can cause the blood vessels to narrow.
• Poor sleep patterns : Sleeping <6 hours or having sleep apnea has been shown to raise blood pressure. Poor sleep quality contributes directly to the development of prehypertension and hypertension.

3. Risk Factors for Prehypertension in Teens and Children

Prehypertension is now increasingly found in young people. The Indonesian Pediatric Society (IDAI) emphasizes the importance of checking blood pressure from the age of 3, especially when risk factors are present.

• Sedentary habits (high screen time) : Too little movement and physical activity makes blood pressure rise more easily.
• Obesity in children and teens : Visceral fat affects hormones and the metabolic system, which significantly increases the risk of prehypertension.
• Certain medical history : Kidney disorders, endocrine disorders, or congenital heart disease can affect blood pressure regulation from a young age.
• The importance of early detection : Prehypertension in children often goes undetected, so routine checks are important to keep the condition from progressing to hypertension in adulthood.

Why Is It Important to Understand the Risk Factors for Prehypertension?

Knowing the causes and risk factors allows you to:

• Recognize what needs to be changed or monitored,
• Understand your personal and family risk,
• Carry out early detection for children and teens, and
• Prevent long-term complications such as hypertension, stroke, and heart disease.

05 / Heart Disease

Can Prehypertension Go Away?

Many people ask whether prehypertension can go away. The good news is that this condition can be controlled and can even return to the normal blood pressure category if it is addressed early. The right lifestyle interventions can lower blood pressure by a few points, enough to move out of the prehypertension zone.

In other words, prehypertension is not a life sentence, but an opportunity to prevent hypertension before long-term damage to the heart and blood vessels occurs.

1. Can Prehypertension Return to Normal?

Yes, prehypertension can return to normal (<120/<80 mmHg). Large studies such as the DASH Study show that structured lifestyle changes can lower systolic blood pressure by up to 11 mmHg, a very significant amount for preventing prehypertension from progressing to hypertension.

Some steps that have been shown to help lower blood pressure:

• Reducing salt intake,
• Increasing physical activity,
• Losing weight,
• Improving your diet,
• Managing stress, and
• Improving your sleep patterns.

In addition, routine blood pressure checks help monitor how your condition is developing accurately.

2. When Should You Consult a Doctor?

Although prehypertension can be controlled through lifestyle, some conditions require a doctor’s care to make sure it does not progress toward hypertension. You should see a doctor if:

• Your blood pressure is consistently in the range of 120 to 139/80 to 89 mmHg : This consistency may indicate prehypertension that requires a more in-depth assessment of your risk factors.
• Bothersome symptoms appear : Although it often has no symptoms, some people report headaches, dizziness, heart palpitations, and tiring easily. These symptoms can be a signal that additional evaluation is needed.
• You have risk factors such as a family history, obesity, or diabetes : These factors speed up the change from prehypertension to hypertension.
• You are pregnant or planning a pregnancy : Slightly elevated blood pressure can pose risks during pregnancy and needs close monitoring.
• You are taking certain medications : Some medications (for example, corticosteroids or certain NSAIDs) can raise blood pressure.

In these situations, your doctor may order further tests such as an ECG, blood tests, or kidney tests to make sure your condition remains safe.

3. Signs That Prehypertension Is Progressing to Hypertension

Prehypertension needs monitoring because it can shift into hypertension if it is not controlled. The following conditions may indicate this transition:

• Blood pressure readings reach ≥140/90 mmHg on repeated measurements : These numbers may be a sign of hypertension; have it confirmed through a doctor’s examination.
• Blood pressure rises steadily over time : For example, from 122/82 to somewhere between 135/85 and 139/89 within a few weeks for no clear reason.
• Symptoms become more frequent or more intense : These include:
  • severe headaches,
  • recurring dizziness,
  • more frequent heart palpitations,
  • excessive tiredness,
  • blurred vision.
• Supporting test results show changes : For example, declining kidney function or early signs of an enlarged heart.

If these signs appear, a doctor’s examination should be done sooner so that complications can be prevented.

Prehypertension can indeed go away, but it requires commitment and the right strategy. The next important step is to understand how to prevent prehypertension from turning into hypertension, especially if you have risk factors or blood pressure readings that often go up and down.

06 / Heart Disease

How to Prevent Prehypertension From Progressing to Hypertension

Prehypertension is an early signal that blood pressure is starting to move above normal. To begin with, this condition is not yet hypertension, but prehypertension can progress to hypertension if it is not managed early. That is why preventive steps are very important. In addition, the right lifestyle changes have been shown to help lower blood pressure and protect heart health in the long term.

1. Managing Your Diet: The Main Foundation of Prevention

Managing your diet is one of the important steps in preventing prehypertension from progressing to hypertension. According to American Heart Association (AHA) guidelines, a diet that is low in salt and rich in nutrients can help lower blood pressure gradually.

A Low-Salt Diet

• Limit sodium to <2,300 mg/day (ideally 1,500 mg/day, according to the AHA).
• Cut back on instant seasonings, salty sauces, and processed foods.
• Choose fresh ingredients more often.

Eat More Fruits & Vegetables

Fruits and vegetables contain potassium, which helps balance excess sodium. Good choices: bananas, spinach, broccoli, oranges, avocados, tomatoes.

Cut Back on High-Sodium Foods

Avoid:

• Canned foods
• Chips and processed snacks
• Sausages, nuggets, or other processed meats
• Fast food

Recommended Foods for Prehypertension

• Fatty fish (omega-3)
• Low-fat yogurt
• Nuts and legumes
• Whole grains
• Olive oil

2. Regular Physical Activity (150 Minutes/Week)

Regular exercise can lower blood pressure by 5 to 8 mmHg. Although it sounds simple, consistency is key.

Examples of Effective Exercise

• Brisk walking for 30 minutes
• Cycling
• Swimming
• Light jogging
• Aerobics
• Strength training 2 to 3 times/week

In addition, physical activity helps control body weight, two important benefits at once in preventing prehypertension from becoming hypertension.

3. Maintaining an Ideal Body Weight

According to Mayo Clinic, losing 1 kg of body weight can lower blood pressure by about 1 mmHg.

One of the recommended steps is to combine a healthy diet with regular physical activity. What’s more, losing 5 to 10% of your total body weight is already enough to make a significant difference.

4. Stress Management: Controlling Blood Pressure Triggers

Chronic stress can keep blood pressure persistently high. That is why managing stress is an important strategy if you have prehypertension.

Breathing Techniques

• Deep breathing
• Box breathing
• 4-7-8 breathing

These techniques help ease tension in the nervous system so that blood pressure is more stable.

Get Enough Sleep

The Centers for Disease Control and Prevention (CDC) recommends 7 to 9 hours of sleep a night for optimal heart health. Lack of sleep has been shown to increase the risk of prehypertension and hypertension.

Relaxing Activities

• Meditation
• Yoga
• Journaling
• Leisurely walks outdoors

5. Quit Smoking & Limit Alcohol

Quit Smoking

Each cigarette causes a blood pressure spike that lasts 20 to 30 minutes. If this happens continuously, blood vessel damage occurs more quickly.

Limit Alcohol

The American Heart Association (AHA) recommends:

• 1 drink/day for women
• 2 drinks/day for men

Excessive alcohol leads to higher blood pressure, fluid retention, and weight gain.

By applying the strategies above consistently, your chances of preventing prehypertension from progressing to hypertension increase significantly. In fact, many people have managed to bring their blood pressure back to the normal category through healthy lifestyle changes alone. In addition, these steps offer extra benefits such as more energy, better sleep quality, and a stronger, healthier heart.

07 / Heart Disease

Prehypertension in Teens: Is It Dangerous?

Prehypertension in teenagers has become increasingly common in recent years. This condition needs serious attention because it can develop into hypertension in adulthood. In fact, the American Academy of Pediatrics (AAP) and the Indonesian Pediatric Society (IDAI) emphasize that above-normal blood pressure at a young age should not be ignored, especially when it comes with unhealthy habits such as too little physical activity, eating fast food, and very long hours of gadget use.

Main Causes of Prehypertension in Teens

1. Sedentary Lifestyle (High Screen Time)

Indeed, one of the main triggers of prehypertension in teens is sitting for too long. Using gadgets for more than 3 to 4 hours a day, whether for studying or entertainment, means the body rarely moves. In addition, low physical activity has been shown to reduce insulin sensitivity and increase the tendency for blood pressure to rise.

2. Obesity and a High-Salt Diet

• Eating fast food
• Sweetened or high-sugar drinks
• Salty snacks

High-salt foods can raise blood pressure from a very young age. In addition, obesity makes the blood vessels work harder, so blood pressure rises gradually.

3. Lack of Sleep

Getting less than 8 to 10 hours of sleep increases stress hormones and can affect blood pressure regulation. Teens who often stay up late have a higher risk of prehypertension.

4. Family History

Children whose parents have hypertension are at greater risk of prehypertension. PERKI emphasizes that genetic factors play a strong role in blood pressure at a young age.

Long-Term Risks If Prehypertension Is Left Untreated

1. Potential to Progress to Hypertension

Teens with above-normal blood pressure have a 2 to 4 times higher risk of developing hypertension as adults.

2. Gradual Organ Damage

If this condition is left untreated, the following can occur:

• Thickening of the left heart wall
• Impaired kidney function
• Reduced elasticity of the blood vessels

3. Higher Risk of Heart Disease at a Younger Age

Hypertension that begins in the teenage years is associated with coronary heart disease at a young age.

4. Psychological Impact

Unstable blood pressure can affect sleep quality, concentration, emotions, and academic performance.

How Modern Lifestyles Affect Prehypertension in Teens

1. Excessive Gadget Use

Long screen time leads to too little movement, stress, and sleep problems, three factors that directly affect blood pressure.

2. A Fast-Food Diet

Most fast food contains very high amounts of salt, added sugar, and trans fat. On top of that, drinks such as bubble tea and energy drinks also contribute to higher blood pressure and weight gain.

3. Too Little Daily Physical Activity

Even active teens often do not reach the minimum recommendation of 60 minutes of moderate-intensity physical activity per day.

When Should Parents Be Concerned?

Parents should be more alert if their teenager:

• Eats fast food or salty snacks every day
• Spends more than 3 to 4 hours on screens
• Gains weight quickly
• Often complains of headaches or tires easily
• Has a family history of hypertension

In addition, if blood pressure readings at home or at a health facility are at the upper limit of normal, further checks are needed. This is not only to confirm whether prehypertension has developed, but also to prevent progression to hypertension.

08 / Heart Disease

When Should You Get Checked by a Doctor?

Prehypertension often develops slowly, so early monitoring helps prevent it from getting worse and protects your heart health in the long term. Here are some signs you should pay attention to.

1. Blood Pressure Consistently Above 120/80 mmHg

If your blood pressure readings are in the range of 120 to 139 / 80 to 89 mmHg over several measurements, these numbers may be a sign of elevated blood pressure or prehypertension; have it confirmed through a doctor’s examination.

To make sure the results are accurate:

• Measure while calm, after resting for at least 5 minutes.
• Take measurements at different times.
• Use a validated blood pressure monitor.

If the numbers stay above normal, a medical examination is strongly recommended.

2. Troublesome Symptoms Appear

Prehypertension often causes no complaints. However, you should watch out for the following symptoms:

• Dizziness or lightheadedness
• Heart palpitations
• Tiring easily
• Recurring headaches

These symptoms may indicate that the body is dealing with increased pressure in the blood vessels. In addition, they may be related to other cardiovascular conditions that need to be evaluated.

3. Having Comorbidities That Increase Risk

Not only slightly elevated blood pressure readings, but also certain comorbidities can cause prehypertension to progress to hypertension more quickly. For example:

• Diabetes
• Obesity or excess belly fat
• High cholesterol
• A family history of heart disease or hypertension

If you have any of the conditions above, consulting a doctor is strongly recommended to reduce the risk of further complications.

4. The Importance of Early Cardiovascular Risk Evaluation

An early medical evaluation offers many benefits. Your doctor can:

• Assess your long-term cardiovascular risk.
• Identify early signs of organ damage (for example, an enlarged heart or declining kidney function).
• Provide personalized recommendations on diet, physical activity, and blood pressure monitoring.
• Determine whether additional therapy is needed to prevent progression to hypertension.

In fact, prevention is more effective while a person is still at the prehypertension stage, not after hypertension has developed.

5. You Are Not Alone: Medical Professionals Are Ready to Support You

Dealing with prehypertension can be worrying, but you are not alone. We understand that every blood pressure number means something for your health. That is why medical professionals are ready to help with an approach that is warm, clear, and evidence-based.

From education and routine checkups to a focused treatment plan, medical support can be an important step in keeping your heart healthy.

09 / Heart Disease

Recommended Tests and Screening for Prehypertension

Regular health screening is very important for anyone in the prehypertension phase. Slightly elevated blood pressure often causes no symptoms. However, it is at this stage that the risk of hypertension and heart disease can grow without you realizing it. That is why the right tests help detect problems earlier, assess blood vessel health, and show how your heart works every day.

In addition, early detection is a key step in preventing cardiovascular complications.

Why Is Heart Screening Important?

Detecting Risks Earlier

Blood pressure in the prehypertension range often progresses to hypertension if it is not monitored. With screening, your doctor can see early signs of cardiovascular problems before they cause serious complaints.

Assessing Blood Vessel Health

Prehypertension can put extra pressure on the artery walls. Certain tests help assess the elasticity and thickness of the blood vessels, making long-term risks, such as heart disease and stroke, easier to anticipate.

Understanding the Heart’s Workload

Even a slight rise in blood pressure can make the heart work harder. Heart tests help determine whether there are structural or functional changes that need further monitoring.

Commonly Recommended Tests

To make sure prehypertension stays under control, doctors usually recommend several types of tests. Each test has a different purpose, and they complement one another.

1. Regular Blood Pressure Measurement

This is the most basic and very important test. Do it routinely, for example:

• 2 to 3 times per week
• At the same time each day
• Using a validated blood pressure monitor

A record of your readings helps your doctor see your blood pressure pattern over time.

2. Blood Tests: Lipid Profile & Blood Sugar

Besides blood pressure, cholesterol and blood sugar levels also determine whether prehypertension may progress more quickly. The tests usually include:

• LDL, HDL, triglycerides
• Fasting blood sugar (FBS)
• HbA1c, especially if there is a risk of diabetes

The Indonesian Ministry of Health (Kemenkes) and the CDC also include these tests as an important part of screening for heart and metabolic disease.

3. Electrocardiogram (ECG)

An ECG helps detect rhythm disorders, the heart’s workload, or early signs of problems in the heart muscle. This test is simple and does not cause pain.

4. Echocardiography (Heart Ultrasound)

This heart ultrasound test is recommended if your doctor finds:

• A significant rise in blood pressure
• Complaints such as palpitations or shortness of breath
• Suspected changes in the structure of the heart

Echocardiography provides detailed information about how well the heart pumps.

5. Blood Vessel Tests

To assess the risk of atherosclerosis and blood flow problems, your doctor may recommend:

• Arterial & venous Doppler
• Carotid IMT
• Ankle-Brachial Index (ABI)

These tests are especially useful when prehypertension comes with other risk factors, such as high cholesterol or smoking.

Recommended MCU Packages at Heartology Cardiovascular Hospital

Heartology Cardiovascular Hospital offers several checkup packages that are relevant if you are in the prehypertension phase. Each package is designed to meet specific needs, from basic screening to an in-depth evaluation of blood vessel health.

1. MCU Cardiovascular Prime Screening, a comprehensive checkup that includes a complete cardiovascular risk evaluation.
2. MCU All Hearts All Care, a suitable option for families who want thorough heart health screening.
3. MCU Vascular Health & Wellness, focused on blood vessel health, which is important for people with metabolic risks.
4. MCU Cardiac Sportacular, suitable for people who exercise actively or are starting a high-intensity training program.
5. MCU Children Wellness, suitable for children and teens at risk of developing prehypertension early in life.

The right screening helps you understand your heart condition, estimate your risks, and take more effective preventive steps. Once you know which tests you need, the next step is to learn which foods are safe and which should be limited to keep your blood pressure stable.

Foods for Prehypertension: What to Eat and What to Avoid

Managing your diet is one of the important ways to help control prehypertension. In fact, guidelines from the American Heart Association (AHA) and the DASH (Dietary Approaches to Stop Hypertension) eating plan show that the right food choices can lower blood pressure significantly. That is why understanding which foods are recommended and which should be limited is an important step in keeping prehypertension from progressing to hypertension.

Below, you will find an easy guide that you can apply right away to your daily meals.

Recommended Foods for Prehypertension

The following foods support the health of the heart and blood vessels.

1. Green Vegetables

Green vegetables are rich in potassium, magnesium, and fiber, three important nutrients that help lower blood pressure. Examples:

• Spinach
• Broccoli
• Kale
• Mustard greens (sawi)
• Lettuce

Why is this important?

Potassium helps balance sodium levels so that blood pressure is more stable.

2. High-Potassium Fruits

These fruits can help lower blood pressure naturally. Examples:

• Bananas
• Avocados
• Oranges
• Kiwis
• Melons
• Papayas

In addition, fruit can be a healthier snack alternative to processed foods.

3. Fatty Fish (Omega-3)

Omega-3 helps reduce inflammation and lower the risk of heart disease. Examples:

• Salmon
• Sardines
• Mackerel
• Tuna

Eating fish 2 to 3 times/week is highly recommended to support heart function.

4. Complex Carbohydrates

Complex carbohydrates help keep blood pressure stable. Examples:

• Oats
• Brown rice
• Quinoa
• Whole wheat bread

Foods to Limit

Some types of food can worsen prehypertension, especially those high in salt, saturated fat, and additives.

1. High-Salt Foods

Salt is one of the main factors that raise blood pressure. Examples:

• Salty chips
• Instant seasonings
• Bottled sauces
• Salty soup-based dishes

A sodium intake of <1,500 mg per day is strongly recommended for people with high blood pressure or prehypertension.

2. Packaged/Instant Foods

These usually contain fairly high amounts of sodium, preservatives, and MSG. Examples:

• Instant noodles
• Ready-to-eat sausages
• Canned meat
• Packaged snacks

If they are not limited, these foods can make blood pressure worse.

3. Fried Snacks (Gorengan)

Gorengan (Indonesian deep-fried snacks) are high in trans fat and LDL, which can damage blood vessels. Examples:

• Bakwan (vegetable fritters) and other fried snacks
• French fries
• Fried chicken

4. Processed Meats

Processed meats tend to be high in salt and nitrates. Examples:

• Sausages
• Ham
• Corned beef
• Bacon

Based on research from Harvard and the American Heart Association (AHA), processed meats increase the risk of hypertension and heart disease.

Summary Table: Recommended vs Limited

Category	Recommended	Limit
Vegetables	Spinach, kale, broccoli	Salty canned vegetables
Fruit	Bananas, oranges, avocados	Canned fruit in syrup
Protein	Salmon, tuna, sardines	Sausages, bacon, corned beef
Carbohydrates	Oats, quinoa, brown rice	Instant noodles, white bread
Snacks	Unsalted nuts, fresh fruit	Salty chips, packaged snacks
Prepared foods	Low-salt foods	Fried snacks, fast food

Move Toward a More Balanced Diet

By choosing the right foods, you can help lower your blood pressure, protect your blood vessels, and keep prehypertension from progressing to the hypertension stage. Simple steps such as cutting back on salt, eating more fruits and vegetables, or swapping fried snacks for grilled foods can make a real difference.

How Do You Measure Blood Pressure Correctly?

Measuring blood pressure correctly is very important, especially if you have prehypertension and want to make sure your monitoring stays accurate over time. In fact, small mistakes in measurement technique can cause readings to differ by up to 10 to 15 mmHg, a difference large enough to hide your true prehypertension status.

To help you get consistent, safe, and reliable results at home, here is a complete guide that is easy to follow.

1. The Right Time to Measure Blood Pressure

To get accurate results, blood pressure should be measured at a consistent time every day.

In the morning before your daily activities

• Before breakfast
• Before taking blood pressure medication (if any)
• After sitting quietly for 5 minutes

In the evening before bed

A second measurement will help you monitor how your blood pressure fluctuates throughout the day.

Take 2 readings each session

Two readings taken 1 minute apart are recommended. Use the average as your reference.

Avoid measuring after temporary triggers

Wait at least 30 minutes after:

• Exercising
• Drinking coffee or tea
• Smoking
• Eating a heavy meal

In addition, avoid measuring when you are stressed or have just finished physical activity, so that your prehypertension readings are not distorted.

2. The Right Body Position When Measuring

Body position is one of the factors that most affects the accuracy of a blood pressure reading.

Sit in a stable position

• Sit in a chair with your back straight
• Relax your shoulders
• Do not talk, and do not hold your breath

Leg position

• Feet flat on the floor
• Do not cross your legs
• Do not let your feet dangle

Arm position

• Rest your arm on a table at heart level
• Place the cuff 2 to 3 cm above the crease of your elbow
• Make sure the cuff fits well, not too tight or too loose

Make sure the cuff is directly on your skin

Do not put the cuff over thick clothing, because this can change the pressure reading.

3. Digital vs Manual Devices: Which Is More Accurate?

Both digital and manual devices can be used to monitor prehypertension. However, your choice should match your needs and your ability to read the results.

Digital Device (Recommended for Home Use)

Advantages:

• Practical and easy to use
• Fewer technique errors
• Many models are clinically validated
• More consistent for daily monitoring

American Heart Association (AHA) guidelines recommend a digital device with an upper arm cuff because it is more accurate than a wrist monitor.

Manual Device (Sphygmomanometer + Stethoscope)

Usually used by health professionals because:

• It takes training to recognize Korotkoff sounds
• It needs regular calibration
• The risk of error is higher if you use it yourself

Conclusion:

If you are monitoring prehypertension at home, an upper arm digital device is the recommended choice in terms of accuracy, comfort, and consistent results.

4. Common Mistakes When Measuring Blood Pressure at Home

Although it is simple, many people unknowingly make mistakes that lead to inaccurate readings.

Frequent mistakes

• Using a cuff that is the wrong size
• Crossing your legs during the measurement
• Holding your arm too low or too high relative to your heart
• Talking or moving during the measurement
• Measuring after drinking coffee or smoking
• Measuring while feeling anxious or rushed
• Not resting for 5 minutes first

Tips for More Accurate Results

• Measure at the same time every day
• Record your results in an app or logbook
• Use a cuff that fits your arm circumference
• Have your device checked regularly at a health facility to validate it

Why Is Correct Measurement Important for Prehypertension?

Blood pressure at the prehypertension stage can look normal if it is not measured correctly. That is why an accurate technique is very important, because it:

• Helps you monitor whether blood pressure is starting to rise toward hypertension
• Provides clear data for your doctor’s evaluation
• Helps you avoid wrong decisions about treatment or lifestyle
• Detects potentially dangerous changes in your pattern early

In addition, correct measurement gives you better control over your heart health.

Complications If Prehypertension Is Left Untreated

Prehypertension often causes no complaints, but it still puts extra pressure on vital organs, especially the heart and blood vessels. If prehypertension is not treated early, small changes in blood pressure can develop into long-term health problems. That is why understanding the risks is not meant to frighten you, but to help you take preventive steps sooner and more effectively.

1. Risk of Progressing to Hypertension

Prehypertension is the early stage before hypertension. A person with prehypertension is more likely to experience:

• A gradual rise in blood pressure within 1 to 5 years
• A 2× higher risk of developing hypertension compared with people with normal blood pressure

In addition, factors such as a high-salt diet, lack of physical activity, and family history can speed up the progression to hypertension. That is why early detection of prehypertension opens up a great opportunity to prevent it from getting worse.

2. Strain on the Heart and Blood Vessels

Even though it seems mild, blood pressure in the prehypertension range still places an extra workload on the heart. Slightly elevated blood pressure can:

• Force the heart to pump harder
• Cause the artery walls to thicken and become less elastic
• Trigger damage to small blood vessels (microvascular damage)

In addition, these changes happen slowly and often go unnoticed. Prehypertension signals that the body needs lifestyle changes so that organ damage does not continue.

3. Risk of Coronary Heart Disease

One of the most relevant long-term complications is an increased risk of coronary heart disease. A study from the American College of Cardiology (ACC) explains that prehypertension:

• Drives the process of atherosclerosis (fatty plaque buildup)
• Speeds up the narrowing of the heart’s blood vessels
• Increases the risk of reduced blood flow to the heart

In addition, when prehypertension comes with high cholesterol or uncontrolled blood sugar, the risk of heart disease increases more quickly.

4. Long-Term Risk of Stroke

Blood pressure that is only slightly higher than normal is already enough to increase the risk of stroke. Mayo Clinic and Cleveland Clinic explain that prehypertension:

• Increases pressure on the arteries of the brain
• Triggers damage to the small blood vessels of the brain
• Reduces the elasticity of the arteries, especially in older age

In fact, it is these small, continuous changes that increase the risk of stroke over the long term, not sudden spikes in blood pressure.

The Importance of Early Detection

Prehypertension is an important opportunity to prevent hypertension and other cardiovascular complications. With early detection and routine monitoring, you can:

• Notice small changes that often go unfelt
• Prevent organ damage caused by slowly rising blood pressure
• Avoid long-term medication if your blood pressure is controlled early
• Make health decisions based on accurate data

Prevention in the prehypertension phase is much more effective than treatment after hypertension has developed.

Conclusion

Dealing with prehypertension means giving yourself a better chance of preventing hypertension in the future. The first step always starts with self-awareness: knowing your blood pressure numbers, understanding the risks, and starting to build habits that support heart health.

Know Your Blood Pressure Numbers

First of all, it is important to check your blood pressure regularly, especially if your results often fall in the prehypertension category. Early detection helps prevent progression to hypertension or other, more serious complications.

Make Lifestyle Changes Early

Next, start making small changes that have a real impact:

• Reducing salt intake
• Eating more vegetables, fruits, and whole grains
• Maintaining an ideal body weight
• Managing stress and making sure you get enough sleep

These changes not only help lower blood pressure but also improve the health of your blood vessels overall.

Monitor Your Blood Pressure Regularly

One of the recommended ways to monitor prehypertension is to measure your blood pressure regularly. Measuring several times a week is advisable, especially for people with risk factors. That way, you can see a more accurate pattern rather than just a single reading at one moment.

Get Screened If Borderline Blood Pressure Keeps Recurring

If your blood pressure is consistently in the prehypertension category, a comprehensive heart health evaluation is strongly recommended. Cardiovascular screening helps:

• Assess the condition of your organs and blood vessels
• Identify the risk of heart disease earlier
• Determine interventions that match your risk profile

This is not meant to frighten you; it is a preventive step that various international cardiology organizations strongly recommend.

Contact a Doctor When Certain Symptoms Appear

Although prehypertension usually has no symptoms, contact a doctor right away if you experience:

• Recurring dizziness
• Heart palpitations
• Shortness of breath
• Extreme fatigue
• Pressure or discomfort in the chest

Symptoms like these, especially if they appear together with borderline blood pressure readings, need further evaluation to make sure no other condition is developing.

Finally, managing prehypertension is not a journey you have to take alone. At Heartology Cardiovascular Hospital, cardiologists can help you plan suitable prevention and care steps if your blood pressure often rises or if you have risk factors.
