💬 What This Means

Understanding Your BP Numbers

Systolic pressure (top number) is the force your heart exerts on blood vessel walls when beating. Diastolic pressure (bottom number) is the pressure when your heart is at rest between beats.

A reading of 120/80 mmHg ("120 over 80") is considered the benchmark for normal blood pressure. Your blood pressure naturally fluctuates throughout the day based on activity, stress, and hydration.

How to Take an Accurate Reading

For the most accurate result: sit quietly for 5 minutes before measuring, sit upright with your back supported and feet flat on the floor, place the cuff on bare skin at heart level, avoid caffeine, exercise, and smoking for 30 minutes beforehand.

Take 2–3 readings 1–2 minutes apart and average them. Take readings at the same time each day (morning readings are most consistent).

Frequently Asked Questions

What causes high blood pressure? ▼
Most hypertension (90–95%) is "primary" with no single identifiable cause, but risk factors include: age, family history, high salt diet, obesity, physical inactivity, smoking, excessive alcohol, chronic stress, and certain medications. Secondary hypertension (5–10%) is caused by underlying conditions like kidney disease or hormonal disorders.
Can I lower blood pressure without medication? ▼
Yes, for Stage 1 hypertension, lifestyle changes alone can normalise blood pressure: losing 5–10% of body weight, reducing sodium to under 2,300mg/day, exercising 150 min/week, limiting alcohol, quitting smoking, and managing stress. The DASH diet is specifically designed to reduce blood pressure.
What is white coat hypertension? ▼
White coat hypertension occurs when blood pressure is elevated in a medical setting (due to anxiety) but normal at home. It affects about 15–30% of people diagnosed with high blood pressure. Home blood pressure monitoring and 24-hour ambulatory monitoring can help identify this pattern.
