Blood Pressure Chart and Guidelines

In the United States, the National Institute of Health regards as normal, blood pressure readings that are 120/80 or below. The recommendation for anyone with this blood pressure reading is to check their BP once a year.

If the blood pressure readings fall into the range of 120/80 to 139/89 , the person is said to have prehypertension. This means that the person is likely to develop high blood pressure in the future. The person in this range of blood pressure needs to work actively to prevent or delay the development of hypertension. Blood pressure readings of 140/90 of higher on the chart indicate that the person already has hypertension and should be on treatment. You should work with your doctor on how to lower blood pressure. Blood pressure is usually lowered by a combination of blood pressure medications, diet and exercise. The chart below shows normal blood pressure, pre-hypertension, and high blood pressure numbers. Look at the chart below to see where you fit in.

High blood pressure can put undue burden on the heart and make the heart work harder.  Hypertension can also make your arteries get hard, which makes the blood pressure go even higher. It also causes atherosclerosis and the deposit of plaques in blood vessel, which can cause stroke and heart attack.
