Roux-en-Y gastric bypass (RGB):

Obesity surgery at Mumbai in India use exactly the same machines and instruments as the most advanced hospitals in the west. This operation is the most common gastric bypass procedure. First, a small stomach pouch is created by stapling or by vertical banding. This causes restriction in food intake. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum as well as the first portion of the jejunum. This causes reduced calorie and nutrient absorption.

 

Extensive gastric bypass (biliopancreatic diversion):

 

 In this more complicated gastric bypass operation, portions of the stomach are removed. The small pouch that remains is connected directly to the final segment of the small intestine, thus completely bypassing both the duodenum and jejunum. Although this procedure successfully promotes weight loss, it is not widely used because of the high risk for nutritional deficiencies. This procedure is not offered at the clinic.
