Most people who have high blood pressure feel fine, and that is why it is dangerous. It is often called the “silent killer.” It can quietly damage your heart, kidneys, eyes and brain for years before a stroke or heart attack shows up.
Hypertension is very common in Nigeria. A major 2026 review of 32 studies found that hypertension affects roughly one in three Nigerian adults. In one screening study, only a little over half of the people with high blood pressure knew they had it. Rates also vary by region. A nationwide survey found prevalence ranged from 20.9% in the North-Central zone to 52.8% in the South-East.

The good news: blood pressure can be controlled, often with changes that cost little or nothing.
What your blood pressure numbers mean
A reading has two numbers, for example 120/80 mmHg.
- Below 120/80: Normal
- 120–139 / 80–89: Raised. This is a warning zone, so start making changes now.
- 140/90 or higher (on repeated readings): High blood pressure. See a health worker.
- 180/120 or higher: Dangerous. Rest for five minutes and check again. If it is still that high, or you have chest pain, breathlessness, severe headache, confusion or weakness, go to hospital immediately.
Warning signs you should not ignore
Most people have no symptoms. When symptoms do appear, they may include:
- Frequent headaches, especially at the back of the head in the morning
- Dizziness
- Blurred vision
- Nosebleeds
- Chest pain or a pounding heartbeat
- Shortness of breath
Stroke emergency (think FAST): Face drooping, Arm weakness, Speech slurred, Time to get to hospital. Every minute counts.
Who is most at risk?
- Adults over 40
- People with a family history of hypertension
- People who are overweight, especially around the waist
- Heavy users of salt and seasoning cubes
- People who drink alcohol regularly or smoke
- People who rarely exercise
- People living with diabetes or kidney disease
- People under constant stress
10 affordable ways to reduce high blood pressure
1. Check your BP regularly
You cannot manage what you do not measure. Many pharmacies and PHCs check BP cheaply or for free. If you can, buy a validated automatic upper-arm monitor; these are generally more reliable than wrist ones. Check at the same time each day and write the numbers down.
2. Cut down on salt and seasoning cubes
This is the biggest change for most Nigerian homes. Seasoning cubes, salted fish, canned foods, instant noodles and many snacks are loaded with sodium. The WHO recommends less than 5g of salt a day, which is about one level teaspoon in total, including what is already in your food. Try these:
- Use one cube instead of two, then half
- Season with onions, garlic, ginger, scent leaf, uziza, curry and thyme
- Remove the salt shaker from the dining table
3. Eat more fruits and vegetables
Potassium-rich foods help balance the effect of salt. Affordable options include ugu, waterleaf, garden egg, carrots, oranges, bananas, pawpaw, watermelon and avocado (pear).
4. Choose better staples
Swap some white rice and fried foods for beans, unripe plantain, brown rice, oats, millet and boiled yam in moderate portions. Use less palm oil and groundnut oil when frying, and grill, boil or steam more often.
5. Move your body every day
Aim for about 30 minutes of brisk walking five days a week. You don’t need a gym. Walk to the bus stop, take the stairs, or dance to your favourite music at home.
6. Lose some weight if you need to
Losing even 5 to 10% of your body weight can lower blood pressure. Watch your portion sizes, especially at night.
7. Reduce alcohol and stop smoking
Regular drinking raises BP. Smoking damages blood vessels. If you want to quit, ask a health worker for support.
8. Manage stress
Money worries, traffic and work pressure all affect your body. Get enough sleep (7 to 8 hours), take short breaks, pray or meditate, talk to someone you trust, and limit late-night phone scrolling.
9. Take your medication exactly as prescribed
This is where many people get into trouble. Never stop your BP drugs because you feel fine or your reading looks normal. The reading is normal because the drugs are working. Stopping suddenly can lead to a stroke. If cost is a problem, ask your doctor about cheaper generic options, or register with the NHIA or your state health insurance scheme.
10. Be careful with “miracle cures”
Some drinks, such as zobo (hibiscus), may help modestly as part of a healthy diet, but no herb, tea or supplement replaces your prescribed treatment. Some herbal mixtures can even harm the kidneys or interact with your drugs. Tell your doctor or pharmacist about anything you take.
How to take an accurate BP reading at home
- Avoid tea, coffee, smoking and exercise for 30 minutes before.
- Sit quietly for 5 minutes with your back supported and feet flat.
- Rest your arm on a table at heart level.
- Put the cuff on your bare upper arm.
- Don’t talk during the reading.
- Take two readings one minute apart and record both.
Frequently asked questions
Can high blood pressure be cured?
In most people it cannot be cured, but it can be well controlled. Some people with early, mild hypertension bring their readings down with lifestyle changes alone, under medical supervision.
Can young people have high blood pressure?
Yes. More Nigerians in their 20s and 30s are being diagnosed, often linked to weight, diet, stress and family history.
Is it safe to stop my drugs when my BP becomes normal?
No. Only change or stop medication with your doctor’s advice.
How often should I check my blood pressure?
Adults should check at least once a year. If you have high BP, check as often as your health worker advises, often several times a week at first.
Does eating garlic or bitter leaf cure hypertension?
They can be part of a healthy diet, but there is no proof that they cure hypertension, and they should not replace medication.
The bottom line
High blood pressure is common, silent and dangerous, but it can be controlled. Check your numbers, cut down on salt, move more, take your medication faithfully, and share this with someone you love. It could save a life.
