Definition: This calculator determines your blood pressure category based on NHS guidelines using your systolic and diastolic measurements.
Purpose: It helps individuals understand if their blood pressure falls within normal ranges or requires medical attention.
The calculator uses NHS blood pressure thresholds:
Home measurements: Normal <135/85 mmHg
Clinic measurements: Normal <140/90 mmHg
Explanation: Different thresholds are used because blood pressure tends to be lower when measured at home (white coat effect).
Details: Regular monitoring helps detect hypertension early, reducing risks of heart disease, stroke, and kidney problems.
Tips: Enter your systolic (top number) and diastolic (bottom number) blood pressure readings, and specify where the measurement was taken.
Q1: Why are home and clinic thresholds different?
A: Clinic measurements tend to be higher due to "white coat syndrome," so home measurements use slightly lower thresholds.
Q2: What should I do if my reading is high?
A: Consult your GP, especially if you get high readings on multiple occasions.
Q3: When is the best time to measure BP?
A: Take measurements at consistent times, ideally in the morning before medication and in the evening.
Q4: How many readings should I take?
A: NHS recommends taking two readings 1-2 minutes apart and using the average.
Q5: What affects blood pressure readings?
A: Stress, caffeine, exercise, smoking, and full bladder can temporarily raise BP.
