Blood pressure measures how strongly blood presses against the walls of your arteries as it is pumped around the body by your heart. This reading goes up and down as the heart pumps. So, as the heart pumps the blood out, the pressure is highest, and when the heart is filling up again ready for the next pump, the blood pressure is at it's lowest.
Blood pressure is measured in millimetres of mercury (mmHg), and is recorded as two figures. For example, 140/80 mmHg.
The highest reading is the systolic pressure - or the pressure in the arteries when the heart contracts.
The lowest reading is the diastolic pressure - or the pressure in the arteries when the heart rests between each heartbeat.
If you have been diagnosed as having hypertension, or high blood pressure, this means your blood pressure is consistently higher than it ...

The symptoms and signs of high blood pressure are extremely subtle; therefore, you may live with the disease for many years without knowing that you have it. Unfortunately, without detection, it can result in excruciating damage to your heart, blood vessels, kidneys and other parts of the body.
The damage that high blood pressure induces often leads to coronary heart disease , kidney failure or stroke . Medical experts sugge...
Introduction High blood pressure, also called hypertension, is elevated pressure of the blood in the arteries. Hypertension results from two major factors, which can be present independently or together: The heart pumps blood with excessive force. The body's smaller blood vessels (known as the arterioles ) narrow, so that blood flow exerts more pressure against the vessels' walls. Blood pressure is the force applied against the walls of the arteries as the heart pumps blood through the body. The pressure is determined by the force and amount of blood pumped and the size and flexibility of the arteries. Although the body can tolerate increased blood pressure for months and even years, eventually the heart may enlarge (a condition called hypertrophy ), which is a major factor in heart failure .
