Because blood pressure tends to rise as people get older, everyone's risk for high blood pressure increases with age. In addition, some medical conditions can also raise your risk of high blood pressure.
Prehypertension—blood pressure levels that are slightly higher than normal—increases the risk that you will go on to develop chronic high blood pressure.
|Blood Pressure Levels|
|Normal||Systolic: less than 120 mmHg|
Diastolic: less than 80 mmHg
|At Risk (Prehypertension)||Systolic: 120–139 mmHg|
Diastolic: 80–89 mmHg
|High||Systolic: 140 mmHg or higher|
Diastolic: 90 mmHg or higher
Diabetes affects the body's use of a hormone called insulin. This hormone tells the body to remove sugar from the blood. With diabetes, the body either doesn't make enough insulin, can't use its own insulin as well as it should, or both. This causes sugars to build up in the blood. About 60% of people who have diabetes also have high blood pressure.1
