High blood pressure; generally a blood pressure reading of 130/80 millimeters of mercury or higher.

High blood pressure (hypertension) is a condition in which the force of the blood against the artery walls is high enough that it may eventually cause health conditions, such as heart disease and stroke.

Blood pressure is determined by the amount of blood the heart pumps and the amount of resistance to blood flow in the arteries.

There may not be symptoms. Some people have headaches or shortness of breath.

Treatment includes lifestyle changes. Don't smoke, eat a healthy diet and get regular exercise. Some people need medicines.
