Have you recently visited your doctor and heard them say, “Your blood pressure is a bit high, but not quite at the level where you need medication yet”? Or perhaps you know a friend or family member who has been told the same? Many people tend to brush off this “slightly high” pressure reading, thinking, “Well, I don't really have a disease yet.” However, today at Nirogi Lanka, we want to talk about what this really means, why it can be a silent health risk, and how you can take control to stay healthy. Doctors call this condition Prehypertension.
What exactly is Prehypertension? Let’s break it down!
First, let’s understand what Prehypertension is. In simple terms, it means your blood pressure is slightly above the healthy range.
A healthy blood pressure reading is generally around 120/80 mmHg. When your doctor checks your pressure, they give you two numbers: the top number (Systolic pressure) and the bottom number (Diastolic pressure).
With Prehypertension, your top number (systolic) may range between 120 and 139, or your bottom number (diastolic) may range between 80 and 89. If either of these values falls within these ranges, it is categorized as Prehypertension.
Sometimes, doctors may classify a top number between 120–129 and a bottom number under 80 as “elevated blood pressure.” If your top number is 130–139 and your bottom number is 80–89, it might be referred to as “stage 1 high blood pressure.” However, Prehypertension is the umbrella term that covers both of these states.
If your top number is 140 or higher, and/or your bottom number is 90 or higher, that is formally diagnosed as Hypertension (high blood pressure).
Is Prehypertension dangerous? Why should you be concerned?
You might think, “It’s only slightly high, what’s the harm?” The reality is that yes, this is something you should take seriously. Consider this: people with Prehypertension are at two to three times higher risk of developing serious conditions like heart attacks, heart failure, or stroke compared to those with healthy blood pressure levels.
Furthermore, many people with Prehypertension will progress to clinical Hypertension over time. Some studies show that a majority of those with Prehypertension develop full-blown high blood pressure within three to four years. Think of it as a yellow traffic light—if you don’t take precautions now, the red light is not far behind.
How common is Prehypertension?
It is much more common than you might think. Statistics suggest that approximately one in every three adults worldwide has Prehypertension. This is a prevalent issue in Sri Lanka as well, so it is a condition that can affect anyone.
Are there symptoms for Prehypertension?
This is the most concerning part: Prehypertension usually has no specific symptoms. You may not feel any different or experience any discomfort while this issue develops internally. While some people might feel dizzy or fatigued, these are not unique to Prehypertension.
Therefore, the only way to know if you have Prehypertension is to regularly check your blood pressure.
What complications can arise from Prehypertension?
Even without visible symptoms, Prehypertension can lead to internal changes in your body. These are often early signs of Atherosclerosis (where arteries narrow and harden due to plaque buildup). Examples include:
- Thickening of the walls of the main blood vessels (`Carotid artery`) in the neck.
- Enlargement of certain heart chambers.
- Increased calcium deposits in the coronary arteries that supply blood to your heart.
These aren't visible, but they indicate that your body is paving the way for heart disease and stroke.
What causes Prehypertension?
While there isn't one single cause for elevated blood pressure, many lifestyle factors contribute to it:
- Excess Salt Intake: Salt is hidden in many foods—especially in our traditional curries, sambols, and pickles. Store-bought food, such as short-eats and processed/packaged foods, are also typically high in sodium. Consistent intake over time leads to problems.
- Alcohol Consumption: Excessive drinking is a major contributor to rising blood pressure.
- Lack of Exercise: A sedentary lifestyle significantly increases the risk of elevated blood pressure.
For about 95% of people, high blood pressure results from a combination of these lifestyle factors. In the remaining 5% of cases, it may be caused by underlying conditions, such as:
- Sleep apnea
- Kidney disease
- Thyroid disease
Who is at a higher risk of developing Prehypertension?
Certain factors make you more prone to Prehypertension:
- Tobacco use: This applies not just to cigarettes or cigars, but also to smokeless tobacco products (like betel quid with tobacco).
- Body Mass Index (BMI) above 25: Simply put, carrying more weight than is ideal for your height increases your risk. You can easily check your status using an online BMI calculator.
- Family History: If your parents or siblings have high blood pressure, you are genetically more predisposed to Prehypertension or Hypertension.
How is Prehypertension diagnosed?
A single high reading doesn't mean you have Prehypertension. Generally, a doctor will confirm the diagnosis if your pressure is consistently high across at least two or more separate visits on different days.
The test involves a cuff wrapped around your upper arm—it is a quick and painless procedure.
The Prehypertension range is a top number between 120–139 or a bottom number between 80–89.
Do you need treatment for Prehypertension?
Absolutely! This is not a condition that will simply resolve on its own, nor is it something you should ignore. If you don't take steps to manage this Prehypertension now, there is a very high probability that it will gradually progress into high blood pressure (Hypertension). Blood pressure does not improve by itself.
How is Prehypertension treated?
The best news is that for most people with Prehypertension, you can manage this condition without medication, simply by making small, sustainable lifestyle changes. What are these changes?
- Regular Exercise: It is crucial to engage in physical activity that gets your heart rate up for at least 30 minutes a day, on most days of the week. Activities like brisk walking, jogging, cycling, or swimming are all excellent choices.
- Maintain a Healthy Weight: Aim for a healthy weight that is appropriate for your height. If you are overweight, losing even a small amount can make a significant difference.
- Stop Using Tobacco Products: If you smoke, quit completely. If you use other forms of tobacco, stop those as well.
- Dietary Adjustments:
- Reduce Salt: Cut down on the salt you add to your meals. Also, try to limit high-sodium foods (processed foods, fast food, and salted/cured meats) as much as possible.
- Reduce Fat: Limit high-fat, fried foods.
- Increase Intake of Vegetables, Fruits, and Leafy Greens:
- This style of eating is often called the DASH diet (Dietary Approaches to Stop Hypertension). You can learn more about this by consulting your doctor or a registered dietitian.
- Limit Alcohol: If you consume alcohol, do so in moderation. The recommended limits are generally one standard drink per day for women and up to two for men.
- Stress Management: Excessive stress can contribute to elevated blood pressure. Practices like yoga, meditation, and finding healthy ways to relax can be very helpful.
However, if you have other health concerns alongside Prehypertension—such as Diabetes, Kidney disease, or Cardiovascular disease—your doctor may recommend starting Antihypertensive medications. There are many types available. Since some medications may cause side effects, if you experience anything unusual, always talk to your doctor, as they can help adjust your prescription.
What can we do to prevent the development of Prehypertension?
Prevention follows the same principles as treatment. By adopting these habits before reaching the Prehypertension stage, you can significantly reduce your risk:
- Avoid all tobacco products (cigarettes, smokeless tobacco, and even vaping) completely.
- Exercise regularly throughout the week.
- Develop effective methods to manage daily stress.
- Keep your alcohol intake limited.
- Reduce the amount of salt added to your food.
- Strive to maintain a healthy weight.
If I have Prehypertension, what should I expect?
Extensive research has shown that people with Prehypertension have a higher risk of developing heart disease and stroke compared to those with lower blood pressure. Often, Prehypertension progresses to full-blown Hypertension over time, which further increases the risk of kidney disease and Type 2 Diabetes.
However, do not panic! The most important thing is that by recognizing Prehypertension early and modifying your daily habits, you can prevent the development of Hypertension and significantly lower your risk of cardiovascular disease.
When should I see a doctor?
It is vital to visit your primary care physician at least once a year for a comprehensive physical or annual checkup.
If your doctor tells you that you have Prehypertension, they will advise you on how often you need to return for follow-ups. This is essential to monitor whether your lifestyle changes are successfully lowering your blood pressure or if it is trending toward Hypertension, so that medical intervention can be started promptly if necessary.
What questions should I ask my doctor?
When you visit your doctor, consider asking the following questions:
- “Doctor, what specific dietary changes should I make to help lower my blood pressure?”
- “Is medication absolutely necessary for my Prehypertension right now?”
- “How much exercise should I get per day, and what types are best for my blood pressure?”
- “Can you provide more information or resources on reducing my salt intake?”
