Abstract
Hypertension occurs when the blood is under increased pressure, pushing against the walls of your blood vessels. Systolic pressure, the top number of a blood pressure reading, measures the pressure during a heart beat. The bottom number, the diastolic pressure, measures the pressure between heart beats. A normal blood pressure is defined as 120/80 or lower. Blood pressure between 120 to 140/80 to 90 is “pre-hypertension” and any thing over 140/90 is definite hypertension. The number of adults in the United States with high blood pressure (hypertension) has increased 30% over the last decade. At least 65 million people (one-third of adults) in America suffer from hypertension. Hypertension does not usually cause symptoms, so many adults who have hypertension may not even be aware of it. When left untreated, hypertension can lead to coronary heart disease, heart failure, stroke, kidney failure, and other problems such as memory loss. More information about memory loss can be found on the next page. Hypertension can cause damage to blood vessels by causing a build-up inside the blood vessels, making them narrow. This restricts the amount of blood that can flow through them. If the narrowed blood vessel becomes blocked such that no blood can get through, this can lead to a heart attack or a stroke. Even reduced blood flow to the brain can have damaging effects. The brain must have a certain amount of blood flow to work normally. About …
