High Blood Pressure

What is High Blood Pressure? 

When the heart beats, it pumps blood to the arteries and creates pressure in them. This pressure (blood pressure) results from two forces. The first force is created as blood pumps into the arteries and through the circulatory system. The second is created as the arteries resist the blood flow.
If you’re healthy, your arteries are muscular and elastic. They stretch when your heart pumps blood through them. How much they stretch depends on how much force the blood exerts.

Your heart beats about 60 to 80 times a minute under normal conditions. Your blood pressure rises with each heartbeat and falls when your heart relaxes between beats. Your blood pressure can change from minute to minute, with changes in posture, exercise or sleeping, but it should normally be less than 140/90 mm Hg for an adult. Blood pressure that stays above this level is considered high. Your doctor may take several readings over a period before making a judgment about whether your blood pressure is considered to be in a high level range.

High blood pressure directly increases the risk of coronary heart disease (which leads to heart attack) and stroke, especially along with other risk factors.

High blood pressure can occur in children or adults. It’s particularly prevalent in African Americans, middle-aged and elderly people, obese people and heavy drinkers. People with diabetes mellitus (di"ah-BE’teez or di"ah-BE’tis meh-LI’tis) gout or kidney disease have hypertension more often.

High blood pressure usually has no symptoms. It’s truly a "silent killer." But a simple, quick, painless test can detect it.

What do blood pressure numbers indicate?
High blood pressure, or hypertension (hi"per-TEN’shun), is defined in an adult as a systolic pressure of 140 mm Hg or higher and/or a diastolic pressure of 90 mm Hg or higher. Blood pressure is measured in millimeters of mercury (mm Hg).
The higher (systolic) number represents the pressure while the heart is beating.

The lower (diastolic) number represents the pressure when the heart is resting between beats.

The systolic pressure is always stated first and the diastolic pressure second. For example: 122/76 (122 over 76); systolic = 122, diastolic = 76.

Blood pressure of less than 140 over 90 is considered a normal reading for adults. A systolic pressure of 130 to 139 or a diastolic pressure of 85 to 89 needs to be watched carefully. A blood pressure reading equal to or greater than 140 (systolic) over 90 (diastolic) is considered elevated (high).
