Hypertension myth busters

May 1, 2025

How much do you really know about high blood pressure?

Think of three people you know. Odds are that at least one of them has high blood pressure (hypertension). It could even be you. Often called ‘the silent killer’ because it has no obvious symptoms, hypertension can lead to serious health issues, including blindness, stroke and heart attack.

Let’s look at some hypertension myths to help you manage your health.

Myth: I feel fine, so I don’t have hypertension

Fact: There’s a reason why it’s called ‘the silent killer’. You may feel absolutely fine; but your blood pressure is through the roof. Get your numbers checked regularly – any clinic and many pharmacies can do a quick check for free.

Did you know: The ideal blood pressure for healthy adults is between 90/60 and 120/80. The higher number is the pressure when your heart beats; the lower one is when your heart rests.

Myth: It only affects older, overweight and stressed people

Fact: Age, weight and stress can increase your risk, but anyone can develop hypertension, including young, fit people – even children. That’s because your genes, diet, lifestyle and pre-existing medical conditions play a role.

Myth: I don’t add salt to my food, so I don’t need to worry

Fact: Most of our sodium (the mineral in salt that can push up blood pressure) doesn’t come from the saltshaker – it’s in processed and pre-prepared foods like take-away meals. Everyday items like bread, tinned food, cheese and even sweets can pack a hefty sodium punch.

Did you know: The maximum daily allowance of salt is around one teaspoon (5g). Most South Africans eat double that. Read labels carefully, cut down on processed foods and season meals with herbs and spices instead of salt.

Myth: It runs in my family so there’s nothing I can do

Fact: Yes, genetics play a role, but your lifestyle choices have a massive impact. Think of it like road safety: you can’t control other drivers, but you can protect yourself with a seatbelt and careful driving.

Likewise, eating well, staying active, maintaining a healthy weight, reducing stress and avoiding smoking and excessive alcohol can significantly lower your risk.

Myth: I can stop taking medicine when my blood pressure normalises

Fact: Hypertension medicines control hypertension but not the cause. Stopping suddenly can be extremely dangerous. Some people need lifelong treatment, such as those with a genetic tendency for high blood pressure or conditions like diabetes or kidney disease.

In some cases, it may be possible to reduce your medicine by tackling the cause, like losing weight if obesity triggered high blood pressure. It’s vital to work closely with your doctor on medication adjustments and lifestyle-based management.
