Nothing hurts, looks discolored or fails to work. Usually, people with high blood pressure experience no discomfort or outward signs of trouble. Many who have high blood pressure don't know it . Directly or indirectly, high blood pressure accounts for nearly a million deaths a year. Uncontrolled, high blood pressure increases the odds that you'll have a heart attack, a stroke or kidney failure.
Blood pressure is the pressure needed to circulate the blood through the body.
When too much of this force is pressing against the artery walls, it is called high blood pressure. Blood pressure is normally measured with a blood pressure cuff placed on the arm. This is the maximum pressure exerted against the arterial walls while the heart is beating. To diagnose high blood pressure, two or more readings should be taken on at least two or more separate occasions. Researchers haven't discovered specific causes for the majority of people with high blood pressure, but they have learned on some factors that increase the chance that a person will develop it.
