General Information


WHAT IS OBESITY?

The World Health Organization has defined overweight and obesity as abnormal or excessive fat accumulation that may impair health, leading to reduced life expectancy and increased health problems.

Morbid obesity is clinically severe obesity at which point serious medical conditions such as: Type 2 Diabetes, High Blood Pressure, High Levels of triglycerides (a type of blood fat), Knee pain, Heart Attack, Stroke, Cancer, Infertility, Sleep Apnea and even Reduction in Life Span, occur as a direct result of the obesity.

HOW IS OBESITY MEASURED

Body Mass Index (BMI) is commonly used in classifying overweight and obesity in adult populations and individuals. It is defined as the weight in kilograms divided by the square of the height in meters (kg/m2). Norms for the Asian population are given in the table below:-

  Normal   19 - 22.9
  Overweight   23 - 27.9
  Obesity   28 - 32.9
  Severe Obesity   33 - 37.4
  Morbid Obesity   > 37.5
  Super Obesity   > 50.0

WHY WE ARE TALKING OF OBESITY IN INDIA? WE ARE A POOR NATION!

Yes we agree that we are dealing with both under nutrition and over nutrition in India at the same time. According to National family Health Survey -3 nearly 15% of Indian population is Obese. Out of this one third are morbidly obese. Just because of very large population this number becomes huge.

OPTIONS FOR TREATMENT ?

Most non-surgical weight loss programs are based on a combination of diet, behavior modification, and regular exercise. However, published scientific data report that these methods do not help resolve morbid obesity because they fail to help people maintain weight loss. In fact, more than 95% of people regain the weight they lose within a short time after treatment. Bariatric surgery is the only method which leads to sustained and very significant loss of weight. This has been proven beyond doubt.

WHO IS A CANDIDATE FOR BARIATRIC SURGERY?

You are a candidate for bariatric surgery if :
  • Your BMI is more than 37.5. This means, if a 5'6" person weighs 105 Kg or more.
  • Your BMI is 32.5 and above, and you have obesity relatedproblems (co-morbidities). This means, if a 5'6" person weighs 91 Kg. or more and has co-morbidities like Diabetes, Hypertension, OSA, Arthritis etc.
Sometimes, even though the overall BMI is less than 32.5, the fat is concentrated only over the abdomen (Truncal Obesity/Potbelly). This pattern of fat deposit is very harmful to health and therefore other parameters are also considered in these patients. These are:-

(a) Waist circumference : Waist measurement of more than 90 cm. inmales and 80 cm. in females.
(b) Waist Hip Ratio (W/H Ratio) : More than 1 in males and 0.8 in females.

WHAT AM I SUPPOSED TO DO BEFORE SURGERY ?

Preoperative testing includes blood work, ECG, Chest X-ray,Upper Endoscopy, Cardiac Stress test and Echo, Pulmonary Function test.

You may be placed on a high protein, low carbohydrate diet including protein shakes for 2 weeks prior to surgery. This is essential as it reduces the size of your liver and makes the surgery safer.

You will be evaluated by our dietician, physiotherapist, and clinical psychologist who will also guide you regarding post-operative diet and exercise routines.

WHAT ARE THE ILL EFFECTS OF OBESITY ?

Obesity is commonly associated with several diseases (co-morbidities) which negatively impact health and the quality of life. In fact obesity is considered even more damaging than smoking or drinking, as it affects almost all of the major body organs. Problems like increased blood pressure, diabetes, heart attack, stroke, cancer (especially breast, uterus and colon), fatty liver, infertility, polycystic ovaries, arthritis, sleep apnea and asthma are all amplified as a result of obesity. It also leads to psychological problems such as depression, low self-esteem and eating disorders. Untreated obesity can also cause premature death.

CAN OBESITY BE TREATED?


Yes, obesity can be treated. But it involves more than just swallowing a pill or sticking to a diet. It needs a multi-disciplinary approach involving a dietician, physiotherapist, physician, endocrinologist, psychologist, gastroenterologist, cardiologist and a bariatric (weight loss) surgeon. In our Weight Loss Management team offers a full range of options including behavior therapy, diet and exercise and bariatric or weight loss surgery. An endocrinologist will evaluate you for hormonal causes of obesity and look for metabolic complications of obesity. A weight loss plan will be set for you and you will get a consultation with a nutritionist who will discuss your diet plan with you. If you are morbidly obese and have tried other treatment without success, you are a candidate for bariatric/weight loss surgery. Bariatric surgery is the most effective therapy available for the morbidly obese population. It markedly lowers body weight, reduces obesity-related diseases mentioned above, and improves the quality of life.
