Blood pressure is the force with which blood pushes against the artery walls. Each time the heart beats, pressure is created inside the arteries. When the pressure is high, it is called hypertension. High blood pressure increases the risk of heart attack and stroke.
Both the systolic and diastolic pressures are recorded as "mm Hg" (millimeters of mercury). A blood pressure of less than 120/80 mm HG is considered normal. A single high level of blood pressure does not indicate a problem. It is only after measuring blood pressure over several days and weeks, that a diagnosis of hypertension can be made.
It is the pressure inside the artery when the heart contracts and pumps blood through the body. This is represented by the top number.
It is the pressure inside the artery when the heart is at rest and filling up with blood. This is the bottom number.
People with high blood pressure should have their blood pressure monitored routinely and be under the care of a physician, who may prescribe medication.
