Obesity is rapidly increasing problems all over the world, is number 2 preventable causes of death after smoking. This growing rate represents a pandemic that needs urgent attention if its potential morbidity, mortality and endemic tolls are to be avoided.

Classification of obesity

Obesity is characterized by Body Mass Index (BMI) which is calculate by Weight (in Kgs) divided by Height (in meter) squared.

BMI = Weight in Kgs (Height in Meters)²
A BMI of: Classifies one as:
<18.5 Underweight
18.5-24.9 Normal weight
25-29.9 Overweight
30-34.9 Obesity Class I
35-39.9 Obesity Class II
40-49.9 Obesity Class III
50 and above Super Obesity

A BMI more than 30 indicates obesity and it reflected by increased Waist circumference. Waist circumference is a better assessor of metabolic risk than BMI because it’s more directly proportional to metabolic total body fat and the amount of metabolically active visceral fat Morbid obesity: When obesity is so severe that it threatens ones health and affects life span of individual. BMI > 35 with medical problems BMI > 40 without medical problems Indian & Asian population develop more problems at lesser BMI Waist circumference of >102 cm in men & 88 cm in women require urgent attention Waist/hip ratio of 0.95 in men & 0.8 in women needs consideration Other important criteria Waist / Hip ratio The occurrence of heart problems, hypertensions are directly correlated with waist circumference. Waist circumference more than 94cm in men and 80cm women and waist to hip ration more than 0.95 in men and 0.8 in women are associated with increased risk for heart attacks. Waist circumference of 102cm in men and 88 cm in women indicates very high risk for cardiac problems and diabetes and needs definite treatment.

Sarcopenia
