Blood pressure is extremely important to check and monitor because the effects are compounding. If you are unable to keep healthy blood pressure with diet and exercise, you might have to resort to blood pressure medications to help bring your levels within the normal range of 120 over 80. This number represents the systolic and diastolic pressures measured in mmHG. You can have your blood pressure checked by putting a cuff on your arm and using a stethoscope. You will probably need a nurse to check it unless you have an automatic machine.
