Frequently Asked Questions
What is a normal blood pressure reading?
Normal blood pressure is below 120/80 mmHg. Elevated is 120–129 systolic with less than 80 diastolic. Stage 1 hypertension is 130–139/80–89. Stage 2 is 140+/90+. A hypertensive crisis is 180+/120+ and requires immediate medical attention.
How common is hypertension in Nigeria?
Hypertension is extremely prevalent in Nigeria — studies estimate that 30–45% of Nigerian adults have high blood pressure, with many unaware of their condition. It is a leading cause of stroke, heart attack, and kidney failure. Regular monitoring is essential.
What lifestyle changes help lower blood pressure?
Reduce salt intake (many Nigerian processed foods and seasonings like Maggi are high in sodium), increase fruits and vegetables, maintain healthy weight, exercise regularly, limit alcohol, quit smoking, and manage stress. The DASH diet principles are effective and compatible with Nigerian foods.
What Nigerian foods should I avoid with high blood pressure?
Limit: heavily salted or smoked fish, stock cubes (Maggi, Knorr), canned foods, processed meats, palm wine and alcohol, and high-sodium snacks. Increase: fresh tomatoes, leafy vegetables (ugu, spinach), bananas, beans, and low-fat dairy if available.
When should I see a doctor?
See a doctor if your readings consistently show Stage 1 or Stage 2 hypertension. Seek emergency care immediately for Stage 3 (hypertensive crisis: 180+/120+). Also see a doctor if you experience headache, dizziness, chest pain, or shortness of breath alongside high readings.
