Most people with high blood pressure have no symptoms, and may feel quite well. Your doctor may confirm this using a 24-hour blood pressure measurement or getting you to measure your blood pressure at home. Generally, if a person has a blood pressure reading greater than 140/90 mmHg taken at least 3 times at the same clinic, they have high blood pressure.


Most doctors would say that a healthy blood pressure is higher than 90/60 mmHg but lower than about 140/90. Your blood pressure varies from day to day, even moment to moment. Blood pressure is measured in ‘mmHg’, which refers to millimetres of mercury. It is given as 2 figures - highest over lowest or systolic over diastolic. Your blood pressure is a measurement taken of the highest reading (systolic) and the lowest reading (diastolic).
