What Is High Blood Pressure?
Blood pressure is a measure of the amount of pressure the blood exerts on the artery walls when it is being pumped through the body by the heart. Too much pressure can result in damage and health issues.
Blood pressure is measured in millimeters of mercury and is reported using two numbers. The top number, or the systolic blood pressure, measures the pressure during the beat of the heart. The bottom number, the diastolic blood pressure, measures the pressure between beats when the heart is at rest.
A blood pressure that is greater than 140 over 90 is classified as high blood pressure, or hypertension. With high blood pressure your heart has to work harder to pump blood, which can lead to a heart attack, stroke, and kidney failure. This makes it very important to incorporate foods into your diet that help control it.
Blood pressure is usually measured on your upper arm. It is measured on the inside of the elbow at the brachial artery. The brachial artery is the major artery of the arm and carries the blood away from the heart.
