What is a normal blood pressure?
Blood pressure should be measured in all adults by their doctors. Adults, who are diagnosed by their doctors to be at low risk for high blood pressure, should be measured at least every 2 years. Other adults, who are at higher risk for high blood pressure, should be measured more frequently according to their doctors’ recommendations. People with diabetes are at greater risk of developing cardiovascular disease.
Therefore, it is important to lower high blood pressure to reduce the risk of cardiovascular disease.
Systolic blood pressure is the higher blood pressure measured in millimetres of mercury (mm Hg) while the heart beats. The diastolic blood pressure is the lower blood pressure in mm Hg between heart beats.
If you have a systolic blood pressure that is higher than 120 mm Hg or a diastolic blood pressure that is higher than 80 mm Hg, please see your doctor for advice.
