What is high blood pressure?

High blood pressure, also known as hypertension, is when the force of blood flowing through your blood vessels continues to be too high over time.

Nearly half of U.S. adults have high blood pressure. Many don’t even know they have it. The only way to know you have high blood pressure is to have your blood pressure checked. A diagnosis of high blood pressure will need to be made by a health care professional.

Preventing and managing high blood pressure

  • It’s best to avoid high blood pressure altogether. Healthy lifestyle choices such as not smoking, eating a healthy diet and being physically active can help. 
  • If you have high blood pressure, work with your health care professional to control it. This may mean taking medications in addition to making healthy lifestyle changes.

Controlling your blood pressure will help you live a longer, healthier life.
