Weight loss for a morbidly obese patient is a big challenge and often cannot be attained. Bariatric surgery is that superspeciality branch of surgery which deals with weight loss operations. There are three categories of bariatric surgery, restrictive and malabsorptive and combined.

Restrictive procedures include gastric banding and sleeve resection where the stomach volume is effectively reduced. Resection of majority portion of stomach also causes ghrelin level (a hormone produced by stomach responsible for increased appetite) to fall which automatically helps the patient attain satiety after taking a small amount of food. In malabsorptive procedures a bypass (between the stomach and small intestine) is performed with or without a stomach reduction. This causes controlled malabsorption of food material leading to significant weight loss.It can be mentioned here that body mass index (B.M.I) is taken as a guide to measured by dividing the weight of a person in kilograms by the square of the height in meters. W.H.O classifies different categories of weight by B.M.I as follows.

  • Below 20 - Underweight
  • 20 to 25 - Normal weight
  • 25 to 29.9 - Overweight
  • 30 to 34.9 - Obese
  • 35 to 39.5 - Morbidly Obese
  • 40 and above - Super obese
