What do blood pressure numbers mean?

Blood pressure is measured in millimetres of mercury (mmHg) and recorded as two numbers: systolic (top) measures pressure when the heart beats, diastolic (bottom) measures pressure when the heart rests between beats. Normal is below 120/80 mmHg. Elevated is 120-129/<80. Stage 1 hypertension is 130-139/80-89. Stage 2 hypertension is 140+/90+. Hypertensive crisis (above 180/120) requires emergency care. High blood pressure often has no symptoms but damages arteries over time, increasing heart attack, stroke, and kidney disease risk.

What is a healthy blood pressure range for Nigerians?

The same international guidelines apply globally: optimal BP is below 120/80 mmHg. However, people of African descent, including Nigerians, have a higher genetic predisposition to hypertension and tend to develop it earlier and more severely. Therefore, maintaining BP below 120/80 is particularly important. Elevated readings (120-129/<80) should trigger lifestyle changes. Regular BP screening from age 18 is recommended, and earlier intervention is advised compared to other populations due to higher cardiovascular risk.

What are the risk factors for high blood pressure?

Major risk factors include: age (risk increases with age); family history of hypertension; being overweight or obese; high salt intake (common in Nigerian diets with bouillon cubes, processed foods); low potassium intake (low fruit/vegetable consumption); physical inactivity; excessive alcohol; smoking; chronic stress; and certain conditions like diabetes or kidney disease. In Nigeria, urbanisation has increased processed food consumption and sedentary lifestyles, contributing to rising hypertension rates now affecting over 30% of adults.

What lifestyle changes lower blood pressure naturally?

Proven lifestyle modifications: reduce sodium to <2300mg/day (avoid adding salt at the table, limit Maggi cubes); eat more potassium-rich foods (plantains, beans, leafy greens, oranges); DASH diet (high in vegetables, fruits, low-fat dairy, lean protein); regular aerobic exercise (150 mins/week walking, jogging); limit alcohol to <2 drinks/day for men, <1 for women; stop smoking; maintain healthy weight (waist <94cm for men, <80cm for women); manage stress. These changes can lower BP by 10-20 mmHg, comparable to one medication.

How often should I check my blood pressure?

If you have normal BP (<120/80), check at least once every 2 years. With elevated BP (120-129/<80), check annually and start lifestyle changes. Stage 1 hypertension: check every 3-6 months. Stage 2 hypertension: every 1-3 months or as directed by your doctor. In Nigeria, many pharmacies and clinics offer free BP checks. Home monitoring with a validated cuff is encouraged for those with hypertension or risk factors. Always take readings at the same time daily, after 5 minutes of rest, and average two readings.

Can supplements help lower blood pressure?

Several supplements have evidence for BP reduction: Magnesium (300-500mg/day) helps relax blood vessels; Potassium (in food form is preferred, supplements only under medical supervision); Omega-3 fatty acids (fish oil, 2-3g/day) reduce inflammation; CoQ10 (100-200mg/day) may lower systolic BP modestly; Garlic extract (aged garlic, 600-1200mg/day) shows small reductions; Hibiscus tea (daily) has modest BP-lowering effects. Always consult a doctor before starting supplements, as they can interact with BP medications. Supplements are adjuncts, not replacements, for lifestyle changes and prescribed drugs.

When should I see a doctor about my blood pressure?

See a doctor immediately if your BP is above 180/120 (hypertensive crisis) especially with chest pain, shortness of breath, severe headache, or vision changes. For readings consistently above 140/90, make an appointment within a week. For readings 135-139/85-89, see a doctor within a month. If you have diabetes, kidney disease, or a family history of early heart disease, seek medical advice even with mildly elevated BP (130-139/80-89). In Nigeria, hypertension is the leading cause of stroke and heart failure, so early detection and treatment are critical.

Blood Pressure & Hypertension FAQ

Understanding Your Blood Pressure Risk

High blood pressure (hypertension) is called the "silent killer" because it often has no warning signs but dramatically increases your risk of heart attack, stroke, kidney failure, and dementia. In Nigeria, hypertension affects over 30% of adults, yet most are undiagnosed or uncontrolled. Your blood pressure reading is a powerful predictor of future cardiovascular events — every 20 mmHg increase in systolic pressure doubles your risk of dying from heart disease.

Why Nigerians Are at Higher Risk

People of African descent have a genetic predisposition to salt-sensitive hypertension, meaning their blood pressure rises more dramatically with high sodium intake. Nigerian diets often contain high levels of salt from bouillon cubes (Maggi, Knorr), processed snacks, and preserved foods. Additionally, low potassium intake (few fruits/vegetables) and rising obesity rates contribute to earlier onset and more severe hypertension. This calculator takes these factors into account by flagging moderate readings as significant risk for Nigerians.

Lifestyle First, Medication When Needed

For most people with stage 1 hypertension, lifestyle changes can normalise blood pressure within 3-6 months. The DASH diet (rich in vegetables, fruits, low-fat dairy) lowers BP by 8-14 mmHg. Reducing sodium to <1500mg/day (about ¾ teaspoon) can lower BP by 5-10 mmHg. Combining weight loss, exercise (150 mins/week), and stress reduction often achieves results comparable to a single medication. If you are already on BP medication, never stop without medical supervision — these lifestyle measures complement your treatment.
