Bariatric Surgery (also called metabolic surgery) involves one or both of the following:

  • Making the stomach pouch smaller
  • Re-configuring the digestive tract

This leads to several changes in the body, including:

  • Reduction in calorie intake
  • Mal-absorption of what is eaten
  • Change in digestive hormones
  • Change in satiation signals
  • Change in gut flora


Through these multiple paths, bariatric surgery helps obese individuals to lose weight. Bariatric surgery is the only scientifically reliable way to reverse obesity in a sustainable fashion.

How is Bariatric Sugery Performed

There are many types of bariatric surgery. The surgeon would pick and choose the most appropriate one

  • Connector.Connector.

    Sleeve Gastrectomy (SG)

    This procedure is suitable for the people who are on the lower end of obesity spectrum. This is also popular as it is the simplest of the bariatric surgeries to perform. In this, the surgeon makes a sleeve out of the stomach and cuts away the excess portion. It results in marginal calorie restriction and marginal changes of hormonal profile. At LIMA, we recommend this procedure very rarely.

  • Connector.Connector.

    Roux-en-Y Gastric Bypass (RnY)

    This is gold standard of weight loss bariatric surgery. In this, the surgeon makes a small pouch of the stomach and routes the digestive tract to bypass the beginning of the small intestine. Since start of the small intestine is responsible for absorbing certain vitamins and minerals, patients who undergo this procedure must supplement these micronutrients through their life. On the plus side, this surgery produces remarkable weight reduction and reversal of comorbidities, if any.

  • Connector.Connector.

    Mini Gastric Bypass (MGB)

    This procedure is almost like RnY, but for the two minor changes: (a) The stomach is made into a sleeve, instead of a pouch and (b) the small intestine is connected at a later part. Consequently, individiduals who undergo this procedure can eat more than the ones who take up RnY. Hence, this procedure is gaining popularity.

  • Connector.Connector.

    BilioPancreatic Diversion (BPD)

    This proceudre is much like RnY, except that it bypasses huge portion small intestine. Since protein is absorbed in the small intestine, individuals who take up this procedure must consume plenty of protein. For this reason, BPD is suggested only when other procedures have failed. BPD is usually reserved for the super obese.

LIMA can handle any of these surgeries as a scarless procedure. With a scarless procedure, the laparoscopic surgical instruments are inserted through a small incision made at the navel. Since the navel is a natural scar, scar made for the surgery eventually blends into it.
