What is blood pressure?

Blood pressure is a measure of how strongly blood pushes against your arteries as the heart pumps blood through your body.

What is considered high blood pressure?

Your blood pressure does not stay the same all the time. It changes depending on what you are doing or how you are feeling.

Some people experience a higher level of blood pressure continuously, for longer periods of time. When this happens, it forces the heart to work harder, which can lead to many other health problems.1,2

This condition is called high blood pressure, or hypertension. It's a dangerous condition because it often has no symptoms or warning signs.3

U.S. guidelines from the American Heart Association define high blood pressure as any value greater than 130/80 mmHg.1

How does the body control blood pressure?

Your heart and blood vessels are involved in blood pressure control, as well as your kidneys.4 In some people, the nerves connected to the kidneys become excessively active and interrupt the natural process of control, leading to higher blood pressure.5

What causes high blood pressure?

Many factors increase your risk of developing high blood pressure.1

Factors you can control

  • Diet
  • Exercise
  • Smoking

Factors you can’t control

  • Family history
  • Race/ethnicity
  • Age
  • Gender
  • Chronic conditions like diabetes and kidney disease

What are the dangers of high blood pressure?

High blood pressure often shows no symptoms, particularly in the early stages, which is why most people do not realize they have it.3 It can quietly damage your body for years. Once it becomes elevated, it can become a serious condition. If not controlled, it can lead to significantly increased health risks.2,6
