High blood pressure is common in Nigeria, and it is largely silent. Many people discover it only when it has already damaged the heart, kidneys, eyes or brain. That silence is exactly why it earned the name "the silent killer" — and why regular checks matter even when you feel perfectly well.

The good news is that blood pressure responds well to a small number of changes, and those changes work alongside medication rather than instead of it.

Know your numbers

Blood pressure is written as two figures, for example 120/80 mmHg. The first is the pressure as the heart pumps, the second the pressure as it rests between beats. For most adults, a reading consistently at or above 140/90 mmHg indicates hypertension, though your doctor may set a different personal target depending on your age, your kidney function, and whether you have diabetes.

Have your blood pressure checked at least once a year if it has been normal, and more often if it has been raised, if you are overweight, or if hypertension runs in your family. A single high reading is not a diagnosis — it needs confirming on separate occasions.

1. Cut the salt, and watch the cubes

Salt reduction is the single most effective dietary change for blood pressure. The recommendation is under 5 grams of salt a day, which is roughly a level teaspoon from all sources combined.

In most Nigerian kitchens the problem is not only the salt shaker. Bouillon and seasoning cubes, seasoning powders, stock powders and packet soups are heavily salted, and using them generously can take you past the daily limit before you add any salt at all.

  • Reduce cubes and seasoning powders gradually — your taste adjusts within a few weeks.
  • Build flavour with onion, garlic, ginger, pepper, curry, thyme, locust bean and fresh herbs instead.
  • Go easy on dried and salted fish, crayfish, tinned foods and processed meats.
  • Taste before you salt, and keep the shaker off the table.

2. Move most days

Aim for about 150 minutes of moderate activity a week — thirty minutes on five days. Brisk walking counts. So does cycling, swimming, dancing, football and vigorous housework or farm work. Activity of this kind can lower systolic blood pressure by a meaningful margin on its own.

Start where you are. If thirty minutes is unrealistic, begin with ten and build. Consistency matters more than intensity, and if you have heart disease or have been inactive for a long time, ask us before starting something strenuous.

3. Lose weight if you are carrying extra

Weight and blood pressure track closely together, and even modest weight loss produces a measurable fall in pressure. Weight carried around the abdomen is particularly linked to hypertension and diabetes. Combining reduced portions with regular activity works better than either alone.

4. Eat for your blood vessels

  • Potassium-rich foods help counter the effect of salt: bananas, oranges, pawpaw, watermelon, beans, sweet potato, ugu and other leafy greens. If you have kidney disease, ask us first, as potassium needs to be limited in some patients.
  • Fruit and vegetables at most meals.
  • Beans, fish and nuts in preference to large amounts of red and processed meat.
  • Less fried food and less palm oil, and fewer sugary drinks.

5. Limit alcohol and stop smoking

Heavy drinking raises blood pressure directly, and cutting down lowers it. If you drink, keep it modest; if you do not drink, there is no health reason to start.

Smoking stiffens and damages arteries and sharply raises the risk of heart attack and stroke on top of hypertension. Stopping is one of the most valuable things you can do for your heart at any age. Ask us for support.

6. Sleep, and manage stress realistically

Persistent poor sleep and unrelieved stress both push blood pressure up. Loud snoring with pauses in breathing and daytime sleepiness may indicate sleep apnoea, which is closely linked to hypertension and is worth mentioning to us. Prayer, rest, walking, and time with people you trust are reasonable and effective ways to manage stress.

Keep taking your medication

This is where most treatment fails. Because hypertension has no symptoms, people stop tablets once they feel fine, or once a reading comes back normal — but the reading is normal because of the tablets. Stopping without medical advice allows pressure to climb again silently. If you have side effects or the cost is difficult, tell us; there are usually alternatives.

Seek care immediately if you have

Severe headache with a very high reading · chest pain · difficulty breathing · weakness or numbness on one side of the body · difficulty speaking · sudden visual disturbance · confusion · a seizure. Weakness on one side, slurred speech or facial drooping may indicate a stroke, where treatment is time-critical. Do not wait to see whether it passes.
