BMI stands for Body Mass Index and it is considered a reliable indicator of total body fat, which is related to the risk of disease and death. The score measures body weight corrected for height and it is valid for both men and women.  It is widely used in both research and clinical settings because measurements of height and weight are easy, quick, and relatively noninvasive. But BMI does have some limits. Obesity indices cannot be used to distinguish between excessive weight produced by musculature, adipose tissue or water retention. 

The BMI score means the following: 

Underweight        Below 18.5

Normal                18.5 - 24.9

Overweight          25.0 - 29.9

Obesity                30.0 and Above 

 
There are additional factors to consider besides BMI when evaluating your risk for developing chronic disease. These RISK FACTORS include:

• 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

For people who are considered obese (BMI greater than or equal to 30) or those who are overweight (BMI of 25 to 29.9) and have two or more risk factors, the guidelines recommend weight loss. Even a small weight loss (just 10 percent of your current weight) will help to lower your risk of developing diseases associated with obesity. Patients who are overweight, do not have a high waist measurement, and have less than 2 risk factors may need to prevent further weight gain rather than lose weight.

Talk to your doctor to see if you are at an increased risk and if you should lose weight. Your doctor will evaluate your BMI, waist measurement, and others risk factors for heart disease. People who are overweight or obese have a greater chance of developing high blood pressure, high blood cholesterol or other lipid disorders, type 2 diabetes, heart disease, stroke, and certain cancers.
