High Blood Pressure

Frequently Asked Questions

18. How do I know if I need to lose weight to prevent or control my blood pressure?

Two key measures are used to determine if someone is overweight or obese. These are body mass index, or BMI, and waist circumference.

Body mass index (BMI) is a measure of weight in relation to height, and provides an estimate of your total body fat. As your BMI goes up, so do your chances of getting high blood pressure, heart disease, and other health problems. Overweight is defined as a BMI of 25 to 29.9; obesity is defined as a BMI greater than or equal to 30.

See the Body Mass Index Table, available from the National Heart, Lung, and Blood Institute (NHLBI).

Body mass index (BMI) applies to both men and women, but it does have some limits.

That’s why waist measurement is often checked as well. Another reason is that too much body fat in the stomach area also increases disease risk. A waist measurement of more than 35 inches in women and more than 40 inches in men is considered high.
