What is high blood pressure?
Blood pressure is the measurement of the pressure or force of blood pushing against blood vessel walls. The heart pumps blood into the arteries (blood vessels), which carry the blood throughout the body. High blood pressure, also called hypertension, means the pressure in your arteries is above the normal range. In most cases, no one knows what causes high blood pressure.
How is blood pressure recorded?
Blood pressure is written as two numbers, such as 118/72. The first number is the systolic pressure. This is the pressure in the arteries when the heart beats and fills them with blood. The second number is the diastolic pressure. This is the pressure in the arteries when the heart rests between beats.
What is a normal blood pressure reading?
|Type of blood pressure reading||Normal blood pressure||Prehypertension||Stage 1 hypertension||Stage 2 hypertension|
|Systolic||less than 120 mmHg||120-139 mmHg||140-159 mmHg||160 mmHg and above|
|Diastolic||less than 80 mmHg||80-89 mmHg||90-99 mmHg||100 mmHg and above|
|mmHg = millimeters of mercury – the unit of measure for blood pressure|
How will I know if I have high blood pressure?
Your health care provider can tell you if you have high blood pressure by checking your blood pressure with a special meter. You usually cannot feel high blood pressure.
