Elevated blood pressure is harmful to the body because it causes the heart to work harder than normal, leaving both the heart and arteries more prone to injury. High blood pressure also increases the risk of heart attack, stroke, damage to the eyes, kidney failure, atherosclerosis and congestive heart failure. High blood pressure combined with other risks, such as obesity, smoking, high blood cholesterol or diabetes greatly increases the risk for heart attack or stroke. When high blood pressure persists without treatment, the heart must work harder to pump enough blood and oxygen to the bodys organs and tissues. When the heart is over-worked for extended periods of time, the heart tends to enlarge and weaken. Arteries also suffer from elevated blood pressure, becoming scarred, hardened and less elastic over time. The Silent KillerHigh blood pressure is often termed the Silent Killer because it usually has no symptoms. Many people have high blood pressure for many years without knowing about it. The only way to find out if your blood pressure is elevated is to have your blood pressure checked. Blood Pressure ReadingsWhen you have your blood pressure taken, what do the numbers mean? The higher number, or systolic pressure, represents the pressure exerted when the heart is beating. The lower number, or diastolic pressure, represents the pressure exerted when the heart is at rest between beats. The systolic pressure is always stated first. For example, a blood pressure reading of 120 over 80 (120/80) would mean that your systolic pressure is 122 mm Hg and your diastolic pressure is 80 mm Hg. (Blood pressure is measured in millimeters of mercury, or mm Hg). RecommendationsHigh blood pressure (hypertension) is defined as an adult having a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher.
Causes of High Blood PressureThe cause of high blood pressure is largely unknown, although there are certain risk factors that increase an individuals chance for developing high blood pressure:
Treating High Blood PressureIf you have high blood pressure, there is a great deal you can do to reduce it. You and your doctor can determine the most effective treatment for you. Treatment may include a low-fat, low-salt diet, losing weight, quitting smoking, reducing alcohol intake, and getting more exercise. In addition, many medications can be used to reduce and control your high blood pressure. With effective monitoring and treatment, you can help control your blood pressure and reduce your risk of stroke, kidney and heart failure and heart attack. Contact the American Heart Association
