• When blood exerts too much pressure on the inner walls of the blood vessels (the arteries and veins), this is known as high blood pressure or hypertension.

  • For most people with high blood pressure, its exact cause in their case is unknown. However, there are several factors that are known to increase the risk of hypertension, some of which you can control.

  • Most often, people with high blood pressure have no symptoms. Headaches, dizziness, and nosebleeds can sometimes be reported if the blood pressure is very high, but are very rare symptoms. Learn more about high blood pressure symptoms and diagnosis.

  • It is extremely important to treat high blood pressure; over time, it can cause damage to organs such as the eyes, kidneys, brain, and heart. The longer it is left untreated, the greater the damage that is done.
