Hypertension is blood pressure that is often higher than 140/90 millimeters of mercury (mm Hg).
HBP; Blood pressure - high
Blood pressure can vary throughout the day and change with activity. A blood pressure measurement has two numbers:
The top (systolic) number is the blood pressure during the heartbeat.
The bottom (diastolic) number is the blood pressure between beats.
According to the American Heart Association, adults should normally have a blood pressure less than 120/80 mm Hg.
Pre-hypertension is when the top number is 120-139 mm Hg and the bottom number is over 80-89 mm Hg on most measurements. If you have pre-hypertension, you are likely to develop high blood pressure at some time in your life, unless you make lifestyle changes.
High blood pressure can affect all types of people. You have a higher risk of high blood pressure if you have a family history of the disease. High blood pr...
Blood is carried from the heart to all the body's tissues and organs in pipes, called arteries and veins. Blood pressure is the force of the blood pushing against the walls of those pipes. The unit for measuring blood pressure is millimeters of mercury (mmHg). In most people, hypertension , or high blood pressure , is defined as either: a systolic pressure consistently at 140 or higher or a diastolic pressure consistently at 90 or higher. In some groups, such as those with diabetes or kidney disease , a high blood pressure is a systolic blood pressure (top number) of 130 or higher or a diastolic blood pressure (bottom number) of 80 or higher. Each time the heart beats (about 60 to 70 times a minute at rest) it pumps blood out into the blood vessels. When the heart is pumping the blood, it is called systolic pressure. When the heart is relaxing in between beats, your blood pressure falls; this is the diastolic pressure. A normal blood pressure is less than 120 (systolic)/80 (diastolic). If the...
Introduction High blood pressure, also called hypertension, is elevated pressure of the blood in the arteries. Hypertension results from two major factors, which can be present independently or together: The heart pumps blood with excessive force. The body's smaller blood vessels (known as the arterioles ) narrow, so that blood flow exerts more pressure against the vessels' walls. Blood pressure is the force applied against the walls of the arteries as the heart pumps blood through the body. The pressure is determined by the force and amount of blood pumped and the size and flexibility of the arteries. Although the body can tolerate increased blood pressure for months and even years, eventually the heart may enlarge (a condition called hypertrophy ), which is a major factor in heart failure .
