What the Numbers Mean?
Systolic (top number): pressure when heart contracts. Diastolic (bottom number): pressure between beats. Normal: under 120/80. Elevated: 120–129 / under 80. High Stage 1: 130–139 / 80–89. High Stage 2: 140+ / 90+. Crisis: over 180/120 — seek urgent care.
When to Measure?
Take readings when rested (5 minutes sitting quietly). Avoid caffeine, exercise, and smoking for 30 minutes prior. Measure both arms initially — use the arm that consistently gives the higher reading. Multiple readings over time are more meaningful than a single measurement.
What's the key thing to understand about Lowering Blood Pressure?
Lifestyle factors that lower blood pressure: reducing salt intake, increasing exercise, maintaining healthy weight, reducing alcohol, quitting smoking, and stress management. DASH diet has strong clinical evidence. For Stage 2 hypertension, medication is usually recommended alongside lifestyle changes.
When to Seek Medical Advice?
Calculator results are estimates based on population averages and statistical formulas — they are not medical diagnoses. Consult your GP if calculator results suggest a health concern, if you have symptoms requiring attention, or if you are managing a chronic condition where precise monitoring is important. Regular health checks (annual GP review, NHS Health Check for those aged 40-74) provide professional assessment using validated clinical tools. Use health calculators to inform conversations with your GP, not to replace them. These tools give a useful starting estimate, but only a healthcare professional can assess your individual circumstances — always seek medical advice for any persistent, worsening, or concerning symptoms rather than relying on a calculator result alone.
