Obesity and Bariatric Surgery

Bariatric Surgery or Metabolic Surgery includes a variety of procedures performed on people who are obese. Weight loss is achieved by reducing the stomach size with a gastric band or through removal of a portion of the stomach sleeve gastrectomy or biliopancreatic diversion with duodenal switch. Gastric bypass surgery is the only treatment option available for achieving prolonged weight-loss. Weight loss surgery has advanced over the years with jejunoileal bypass being one of the attempts at surgical weight reduction. Then came about laparoscopic vertical banded gastroplasty (LVBG), followed by Roux-en-Y gastric bypass surgery (RYGB), which is now the most commonly performed bariatric Surgery. Laparoscopic sleeve gastrectomy (LSG)  is a single-stage operation for treatment of morbid obesity and requires less postoperative followup.
