High Blood Pressure (Hypertension)

High blood pressure is a medical condition where the heart works harder to pump blood around the body at a higher pressure than normal through your arteries. It is also a major risk factor for heart attack, stroke, aneurysms and blood clots.

What is it?

High blood pressure, also called hypertension, can quietly damage the body for years before symptoms appear. Without treatment, high blood pressure can lead to disability, a poor quality of life, or even a deadly heart attack or stroke.

Blood pressure is measured in millimeters of mercury (mm Hg). In general, hypertension is a blood pressure reading of 130/80 mm Hg or higher.

Treatment and lifestyle changes can help control high blood pressure to lower the risk of life-threatening health conditions.

Damage to the arteries

Healthy arteries are flexible, strong and elastic. Their inner lining is smooth so that blood flows freely, supplying vital organs and tissues with nutrients and oxygen.
Over time, high blood pressure increases the pressure of blood flowing through the arteries. This may cause:

  • Damaged and narrowed arteries. High blood pressure can damage the cells of the arteries’ inner lining. When fats from food enter the bloodstream, they can collect in the damaged arteries. In time, the artery walls become less elastic. This limits blood flow throughout the body.
  • Aneurysm. Over time, the constant pressure of blood moving through a weakened artery can cause part of the artery wall to bulge. This is called an aneurysm. An aneurysm can burst open and cause life-threatening bleeding inside the body. Aneurysms can form in any artery. But they’re most common in the body’s largest artery, called the aorta.


Most people with high blood pressure have no symptoms, even if blood pressure readings reach dangerously high levels. You can have high blood pressure for years without any symptoms.

A few people with high blood pressure may have:

  • Headaches
  • Shortness of breath
  • Nosebleeds

However, these symptoms aren’t specific. They usually don’t occur until high blood pressure has reached a severe or life-threatening stage.

How’s your blood pressure?
