Hypertension is the term used to describe high blood pressure.

Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as two numbers. For example, 120 over 80 (written as 120/80 mmHg).

• The top number is your systolic pressure, the pressure created when your heart beats. It is considered high if it is consistently over 140.
• The bottom number is your diastolic pressure, the pressure inside blood vessels when the heart is at rest. It is considered high if it is consistently over 90.

High blood pressure can affect all types of people. You have a higher risk of high blood pressure if you have a family history of the disease. Smoking, obesity, and diabetes are also risk factors for hypertension.
