- Blood pressure is a measurement of the force your blood puts on blood vessel walls as it travels through your body.
- Blood pressure reading is expressed with two numbers; for example, 120/80
- High blood pressure (hypertension) is the most important known risk factor for stroke. High blood pressure can cause damage to blood vessel walls, which may eventually lead to a stroke.
- You can control your blood pressure by changing your diet and lifestyle. You can do this particularly through regular exercise and maintaining a healthy weight.
- Risk factors that have been linked to high blood pressure include: family history, age, overweight, smoking, diabetes, lack of exercise and high alcohol intake.
- High blood pressure can cause blood clots or plaque (cholesterol and other fat-like substances) to break off artery walls and block a brain artery causing a stroke.
- The lower your blood pressure, the lower your risk of stroke.
