Your blood pressure is a measurement taken of the highest reading (systolic) and the lowest reading (diastolic). It is given as two figures - highest over lowest or systolic over diastolic.
Your blood pressure varies from day to day, even moment to moment. Most doctors would say that a healthy blood pressure is higher than 90/60 mm/Hg but lower than about 140/90. Optimal blood pressure is 120/80.
High blood pressure
Generally, if a person has a blood pressure reading greater than 140/90 taken at least twice at the same clinic, they have high blood pressure. Your doctor may confirm this using a 24-hour blood pressure measurement.
Most people with high blood pressure have no symptoms, and may feel quite well. This is why it’s important to see your doctor and have your blood pressure checked regularly, especially if you have one or more of the known risk factors.

Low blood pressure
Most doctors would say that you have low blood pressure if it is below 90/60.
For some people, low blood pressure is a sign of good health. These are generally people who are very fit and who have a slow pulse. For other people, low blood pressure is a problem.
