Frequently asked questions
What is normal blood pressure?
Below 120/80 mmHg is considered normal for adults.
Is 130/85 high blood pressure?
By American Heart Association categories it is stage 1 high blood pressure. International Society of Hypertension guidelines call 130–139/85–89 ‘high-normal’. Either way, it is a signal to adopt healthy habits and talk to your doctor.
Which number is more important?
Both matter. After 50, systolic (top) pressure is a stronger predictor of heart disease and stroke.
When is BP an emergency?
If it is above 180/120 with chest pain, breathlessness, back pain, weakness, vision changes or difficulty speaking, get emergency help immediately.
