High blood pressure (hypertension)Overview

High blood pressure, or hypertension, rarely has noticeable symptoms. But if untreated, it increases your risk of serious problems such as heart attacks and strokes.


High blood pressure, also called hypertension, is when the pressure in your blood vessels is unusually high. It can be serious if not treated.


High blood pressure does not usually have any symptoms. The only way to find out if you have it is to get your blood pressure checked.


Things that increase your chances of high blood pressure include being overweight, having an unhealthy diet, smoking and not exercising enough.


Lifestyle changes like eating a healthy diet and exercising regularly can help lower high blood pressure. Some people also need to take medicines.
