What is Obesity?

obesity The terms "overweight" and "obesity" refer to body weight that's greater than what is considered healthy for a certain height. Obesity is more than just a cosmetic concern as it increases the risk of other health problems and diseases such as heart disease, diabetes, high blood pressure, and arthiritis.


A reliable way to find out about whether you have a healthy weight or are overweight, is to calculate your Body Mass Index (BMI).

It is calculated by the following formula


BMI = Weight (in kilograms)

Height (m) X Height (m)


BMI range - kg/m2 Category
<18.5 Underweight
18.5-23.5 Normal
23.5-27.5 Overweight
27.5-37.5 Obese
> 37.5 Morbidly Obese
> 50 Super Obese
> 60 Super Super Obese


The main causes of obesity are
  • Caloric Imbalance- If you are eating more calories than your body is using. You will store these extra calories as fat and you'll gain weight.
  • Inactive or Sedentary Lifestyle- Lack of adequate physical exercise and leisure activities centred around television / computers, Improved transportation facilities and mechanization of jobs.
  • Food Habits - Easily available processed and unhealthy foods and oversized food portions increase the chances of becoming obese.
  • Genetic make up and body metabolism - some people are more predisposed to weight gain and its effects due to the genetic history. The genes also control how the body handles food (metabilism) and that's why there is no absolute diet formula that applies to all of us. 


One can't change some factors, such as genetic make-up. However, other factors such as lifestyle and food intake are more easily changed. Simple modifications such as following a healthy eating plan and keeping your calorie needs in mind, being physically active and trying to limit the amount of time that you are inactive can help you attain and maintain a healthy weight


Gaining knowledge about the obesity, its causes and associated risks right from childhood is essential as >80% of obese children grow up into obese adults. It is of prime importance to sensitize the school authorities, parents and children about Body Mass Index (BMI). BMI should be and kept within normal range and maintained with a balance of healthy dietary habits and exercise regimes.


What is Morbid Obesity?

Morbid obesity is a chronic and lifelong disease which is associated with several disorders like Type II Diabetes, Hypertension, Cardiac problems, sleep apnea and many others. Being overweight and obese are reversible conditions that can be treated by medical management whereas morbid obesity requires surgical intervention. The body mechanisms that control a person’s weight are set in such a manner in morbidly obese patients that they gain weight easily. These patients find it difficult to lose weight and even more difficult to sustain the lost weight.
