Bariatric Surgery introduced for weight loss and to reduce the size of stomach through the removal of a portion of stomach in combination of both gastric restriction and malabsorption leads to the malabsorption of nutrients, since it restricts the amount of food the stomach can hold and often causes hormonal imbalances. Majority of the weight loss surgeries today are performed through minimal invasive techniques, for instance laparoscopic surgery. Some other includes gastric bypass, adjustable gastric band or gastric banding, sleeve gastrectomy and biliopancreatic diversion with duodenal switch.

Gastric Bypass

Gastric Bypass surgery is a surgical procedure which helps to control the weight by making the patient eat less, since it changes the way the stomach and the small intestine handles the food. Thus, the patient feels full only after eating small portions and hence, ends up eating less. Gastric Bypass or Roux-en-Y Gastric Bypass is regarded as the ‘gold standard’ of the weight loss surgery.

Sleeve Gastrectomy

Sleeve Gastrectomy, also known as Gastric Sleeve Surgery or Laparoscopic Sleeve Gastrectomy is a surgical weight loss procedure which has become a popular choice for majority of patients, since one needs not worry about the long-term maintenance and future complications involved in such medical procedures. In this, a large portion of the stomach is removed and stomach then appears almost 15% smaller than the original size resembling a tubular pouch similar to a banana.

Adjustable Gastric Band

Adjustable Gastric Band, also known as Lap Band or Realise Band is considered as the least invasive weight loss surgery. In this, the surgeon places an inflatable band around the upper portion of the stomach thereby creating a small pouch to hold the food. The main aim behind the placement of this band is to restrict the intake of food, since the patient feels complete after the intake of small portions of food and hence, ends up taking a controlled diet. After the surgery, the surgeon can adjust the band to control the movement of food slowly or quickly into the stomach.

Biliopancreatic Diversion with Duodenal Switch (BPD/DS) Gastric Bypass

It is a two-step surgical procedure quite similar to Sleeve Gastrectomy. It is the most effective weight loss process among all the others. In this, the size of the stomach is reduced by reducing the ability of the stomach to absorb minerals, vitamins and calories, wherein a small tubular stomach pouch is created by making a cut in the belly portion which is followed by bypassing a larger part of the small intestine.
