Calculate Your Body Mass (BMI) Index

Your body mass index (BMI) is a very useful measure of overweight and obesity. It is calculated from your height and weight. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers. Although BMI can be used for most men and women, it does have some limits, in that it may overestimate body fat in people with a muscular build and it may underestimate body fat in older people who have lost muscle.

It just takes a minute to use this BMI calculator and then to look at the BMI classifications below. We have also posted important information on this page about “risk factors”.

Classification	BMI
Underweight Normal Overweight Obesity	Below 18.5 18.5 - 24.9 25.0 - 29.9 30.0 And Above

There are several risk factors that if you are overweight or obese, will put you at greater risk for heart disease and other conditions:

High blood pressure (hypertension)
High LDL cholesterol ("bad" cholesterol)
Low HDL cholesterol ("good" cholesterol)
High triglycerides
High blood glucose (sugar)
Family history of premature heart disease
Physical inactivity
Cigarette smoking

If your BMI index is greater than or equal to 30) or those who are overweight, (BMI of 25 to 29.9) and if you have two or more of the risk factors listed above, We recommend that you talk to your doctor to see whether you are at an increased risk and whether you should lose weight. Your doctor will evaluate your BMI, waist measurement, and other risk factors for heart disease.

The good news is even a small weight loss (between 5 and 10 percent of your current weight) will help lower your risk of developing those diseases.
