Body mass index ( BMI ) is used in epidemiological and clinical practice to define underweight , normal weight , overweight and obesity .
Categorization of obese patients for the eligibility of bariatric surgery has been so far largely on BMI cut – offs, for Asians being 37.5 with no co morbidities and 32.5 with obesity related co morbidities like diabetes, hypertension, hypercholesterolemia, joint pains obstructive sleep apnea etc.
However, BMI is not a biological trait, but a calculated value based on body weight. It does not convey any information on fat distribution (eg : visceral fat accumulation and fatty infiltrations of individual organs), which is now an important determinant of metabolic and cardiovascular risks.
