Hypertension, don't let the pressure get to you

According to the World Health Organization (WHO), uncontrolled high blood pressure or hypertension can lead to strokes (brain attacks), heart attacks, heart enlargement, and eventually heart failure. Hypertension can also damage your blood vessels and lead to aneurysms (weak spots and bulging in your vessels). Additional negative health consequences include possible kidney failure, blindness, and even cognitive impairment.

The Southern African Hypertension Society, estimates that four in 10 adults older than 25 have hypertension. This means that nearly one billion people have hypertension. The unfortunate part is that around 50% of these people are unaware of their condition.

Hypertension is known as a 'silent killer' because there usually aren't visible symptoms to warn that blood pressure is high, which is why it's important to go for a simple screening test at least once a year.

There are two numbers that make up your blood pressure reading: systolic and diastolic. Systolic pressure is the top number and measures the pressure in your arteries when your heart beats. Diastolic pressure is the bottom number and measures the pressure in your arteries when your heart is at rest between beats. A healthy blood pressure reading is typically around 120/80 mmHg. Hypertension is usually defined as when either number (or both numbers) are equal to or above 140/90 mm Hg, when measured on two different days.

Your blood pressure can be checked quickly and easily by a nurse at a pharmacy, clinic, or by your GP. A device called a sphygmomanometer will be used to do this - and it's much easier to use than it is to pronounce! A cuff is placed around the upper arm and becomes tighter as it's inflated to give the blood pressure reading.

High blood pressure can be caused by a variety of factors, including genetics, lifestyle habits, and underlying health conditions. Some risk factors for high blood pressure include smoking, obesity, lack of physical activity, stress, and a diet high in sodium (salt).

If you have been diagnosed with high blood pressure, there are several lifestyle changes you can make to help lower it. These include:

1. Eating a healthy diet: A diet rich in fruits, vegetables, whole grains, and lean proteins can help lower your blood pressure. Avoid processed foods and foods high in sodium.
2. Exercising regularly: Regular physical activity can help lower your blood pressure. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
3. Quitting smoking: Smoking can raise your blood pressure and increase your risk of heart disease. Stopping smoking can help lower your blood pressure and improve your overall health.
4. Managing stress: Stress can cause your blood pressure to rise. Find healthy ways to manage stress, such as meditation, yoga, or deep breathing exercises.

Members on Plan A, Plan B and Plan C have access to a Screening Benefit that funds from the Overall annual in-hospital benefit. This benefit includes funding of selected screening tests to better manage your health, including high blood pressure.
