Obesity has reached epidemic proportions in India in the 21st century, with morbid obesity affecting 5% of the country's population. Morbid Obesity is defined as having a body mass index (BMI) greater than 40.

Obesity impairs a person's mobility, making physical activity difficult, worsening the problem and making the person vulnerable to many diseases such as coronary heart disease, stroke, high blood pressure, fatty liver disease, osteoarthritis, diabetes etc.

While morbid obesity certainly takes a physical toll on the body, it does take a major psychological toll. Some of obesity's worst effects are emotional pain and suffering and fear of social rejection.

Obesity is a life-threatening and socially debilitating condition that may be remedied with weight loss surgery. While weight loss surgery can help morbidly obese people lose weight and improve patients' overall health and extend their lifespan, bariatric surgeries are very serious procedures that should not be taken lightly. In order to be considered for weight loss surgery, certain conditions must be met.

Morbid obesity surgery is becoming an increasingly common procedure to treat individuals with morbid obesity. However, the varying causes of morbid obesity and the plethora of obesity problems further complicate the issue of whether obesity surgery is appropriate for a given individual.

Weight loss surgery is performed only if

1. BMI is 40 or higher
2. The patient has serious obesity-related health problems such as type 2 diabetes, or life-threatening problems like severe sleep apnoea.
3. All other weight loss options like exercise and dieting have been exhausted
4. The patient is ready to accept that the surgery is only a weight loss tool, and he will have to adopt healthy lifestyle changes to be successful in their weight loss endeavours.

Gastric bypass can be done in two ways : in open surgery, the surgeon will make a large incision to open up the belly. The surgeon will do the bypass by directly handling your stomach, small intestine, and other organs. Another way to this surgery is to use a tiny camera, called a laparoscope, which is placed in your belly.
