When the heart beats, it pumps blood round the body to give it the energy and oxygen it needs. As the blood moves, it pushes against the sides of the blood vessels. The strength of this pushing is your blood pressure. If the blood pressure is too high, it puts extra strain on your arteries (and your heart) and this may lead to heart attacks and strokes. Having high blood pressure (hypertension) is not usually something that you feel or notice. It does not tend to produce obvious signs or symptoms. The only way to know what your blood pressure is, is to have it measured. Blood pressure is measured in ‘millimeters of mercury’ (mmHg) and is written as two numbers. For example, if your reading is 120/80mmHg, your blood pressure is ‘120 over 80’. High blood pressure

If normal person may have high blood pressure, this higher pressure puts extra strain on your heart and blood vessels. Over time, this extra strain increases your risk of a heart attack or stroke. Also, high blood pressure can also cause heart and kidney disease, and is closely linked to some forms of dementia[1]. High blood pressure signs and symptoms
