Obesity is a condition, which increasingly threatens public health, and increases rapidly. Although it has been previously described as a behavioral disorder, it is now considered as a disease. Obesity can be defined in tens of ways. However, the most common definition is made on the basis of Body Mass Index (BMI).
BMI = weight/(height)2
For example, if a person has a weight of 70 kg and height of 1.70 meters, then his/her body mass index = 70/1.7x1.7)= 24.2.
Morbid obese: 40-60
Super morbid obese: > 60
Although no exact information is available about the prevalence of obesity for our country, it is estimated to be around 20% whereas in the US, it is around 30%.
