The term "bariatric" is derived from the Greek word "baros" which means "weight." Bariatric surgery is intended to reduce weight. There are three categories of bariatric procedures: purely restrictive (sleeve gastrectomy, Gastric Band, VBG), purely malabsorptive (biliopancreatic diversion) and combined restrictive and malabsorptive (roux-en-Y gastric bypass) depending on whether they involve only reduction of the size of the stomach reservoir to restrict the amount of food consumed by an individual, bypass of a portion of the small intestine to limit the calories and nutrients absorbed from food or a combination of both respectively.

These procedures can be effective in controlling morbid obesity. However, these are complex operations that may be associated with potentially serious complications. Successful outcome and quality of life after these operations depends primarily on the surgeon’s experience and expertise. Therefore individuals considering bariatric surgery should thoroughly search for a surgeon who is dedicated to Bariatric surgery, has completed a fellowship in Bariatric surgery and has excellent track record in Bariatric surgery.
