Frequently asked questions
What is a normal blood pressure?
Less than 120/80 mmHg is considered normal for most adults. 120–129 systolic is 'elevated', and 130/80 or higher is high blood pressure.
One high reading — should I worry?
A single reading can be affected by stress, caffeine or activity. Recheck when calm and rested; if it stays high, or you feel unwell, contact your doctor.
