Understanding South Africa’s Silent Killer: High Blood Pressure

High blood pressure, also known as hypertension, is a common condition that affects millions of South Africans. It occurs when the force of blood against your artery walls is consistently too high. Left unmanaged, it can lead to serious complications such as heart disease, stroke and kidney problems.

Blood pressure readings consist of two numbers. The first, systolic pressure, measures the force when your heart beats. The second, diastolic pressure, measures the force when your heart rests between beats. A reading of 120 over 80 millimetres of mercury (mmHg) is considered ideal. Consistent readings at or above 140 over 90 mmHg indicate hypertension.

High blood pressure often has no obvious symptoms. This is why it is sometimes called the silent killer. You might feel well, yet your heart and arteries are under strain. Regular monitoring is vital, especially if you are over 35 or have a family history of hypertension.

Common Causes and Risk Factors

• Unhealthy diet: consuming too much salt, processed foods and saturated fats.
• Lack of physical activity: leading to excess weight and poor heart health.
• Excess body weight: overweight and obesity increase strain on the heart.
• Stress: long‑term stress can contribute to higher readings.
• Smoking and alcohol: both narrow blood vessels and raise blood pressure.
•  Age and genetics: risk rises as we get older and if close relatives have hypertension.

Possible Signs to Watch For

Many people with high blood pressure notice nothing unusual. However, when blood pressure climbs very high, you might experience:

• Headaches, especially at the back of the head in the morning
• Dizziness or lightheadedness
• Shortness of breath on exertion
• Nosebleeds, though these are rare and often late‑stage

If you notice any of these, arrange to have your blood pressure checked promptly.

When to Get Checked

Visit your pharmacist or doctor if any of the following apply to you:

• You are over 35 or have a family history of hypertension
• Your readings at home or at the clinic average 140 over 90 mmHg or higher
• You have other conditions such as diabetes, high cholesterol or kidney concerns
• You start new medicines that might raise blood pressure

Even if you feel fine, annual checks are wise. A simple machine at home or in our store takes under a minute. It is the best way to catch any problem early.
