Bariatric surgery is a weight loss surgery and a treatment procedure for obesity. There are various types of gastric procedures such as adjustable gastric band, Roux-en-Y Gastric Bypass, Vertical Sleeve Gastrectomy and Biliopancreatic Diversion with a Duodenal Switch (BPD-DS). In Adjustable Gastric Band, a band is placed around the stomach by laparoscopic surgery. This leads to the formation of a pouch which lies above the band and has a capacity of 15-20mL. This procedure reduces patient’s weight either by reducing the amount of food intake or slowing down the emptying from the pouch. Other procedures also offers various advantages to the patient.
