Blood pressure is measured in millimetres of mercury (mmHg) and written as two numbers: systolic (top) over diastolic (bottom). Systolic pressure measures the force when your heart beats, while diastolic measures the force when your heart rests between beats. For example, a reading of 120/80 mmHg means systolic is 120 and diastolic is 80.
According to the American Heart Association (AHA) guidelines, normal blood pressure is below 120/80 mmHg. Elevated blood pressure (120-129 systolic with diastolic below 80) is a warning sign. High blood pressure Stage 1 (130-139/80-89) and Stage 2 (140+/90+) require lifestyle changes and possibly medication. A hypertensive crisis (above 180/120) requires immediate medical attention.
Hypertension (high blood pressure) is Africa's leading risk factor for death and disability. The WHO African region has the highest prevalence of hypertension globally, affecting nearly half of all adults. Yet awareness rates are shockingly low — in many African countries, over 50% of people with hypertension don't know they have it. This "silent killer" often has no symptoms until it causes heart attack, stroke, or kidney failure.
Regular home monitoring is one of the most effective ways to manage blood pressure. Digital blood pressure monitors are increasingly affordable and available across Africa. Take readings at the same time each day, record them, and share with your healthcare provider. This tool helps you understand your readings and track trends over time.
If your reading is consistently above 130/80, see a healthcare provider. Immediate lifestyle changes that help: reduce salt intake, exercise regularly (30 minutes/day), maintain healthy weight, limit alcohol, stop smoking, manage stress, and eat more fruits and vegetables. Your doctor may prescribe medication if lifestyle changes aren't enough.
Yes. Low blood pressure (hypotension) is generally below 90/60 mmHg. While some people naturally have low BP without problems, sudden drops can cause dizziness, fainting, or shock. If you experience symptoms like lightheadedness, blurred vision, or fatigue with low readings, consult a doctor.
