What is it used for?

Written by : DoctorNDTV Team

BMI is used to identify weight problems within a population, usually whether individuals are underweight, overweight or obese.  BMI is frequently used to assess how much an individual's body weight departs from what is normal or desirable for a person of his or her height. The excess weight or deficiency may, in part, be accounted for by body fat although other factors such as muscularity also affect BMI.
