Bariatric Surgery Procedures

The term “Bariatric Surgery” refers to surgical procedures performed to reduce body weight. It has been proved to be the only effective treatment for morbid obesity. In 1991, the National Institute of Health (NIH) Consensus established the guidelines for bariatric surgery for patients with BMI> 35 kg/m2 with severe obesity related comorbidity and for BMI > 40 kg/m2 with or without comorbidity.

There are basically two types of bariatric surgical procedures - Restrictive and malabsorptive. Restrictive procedures reduce the amount of food intake by decreasing the reservoir capacity of stomach whereas malabsorptive procedures decrease the amount of food being absorbed by the intestine. Some procedures have both these effects and are known as combined procedures.

There is a rapid loss of body weight after bariatric surgery during the first six months with a more gradual weight loss which can continue up to 2 years. The percentage of excess weight loss varies with the type of procedure performed and can vary from 50% to 80%.

In the present day scenario, all these operations are performed laparoscopically by the minimal access technique. This reduces the trauma to the abdominal wall and provides ease of access to the organs inside the abdomen. The other advantages of this approach include less pain, superior cosmesis and faster postoperative recovery.

The various common bariatric surgical procedures in modern day practice are the following

This procedure consists of removing the majority of the stomach using laparoscopic staplers to form a banana shaped tube. This reduces the amount of food that can be consumed at one sitting. Also, the fundus of the stomach is removed which is the major source of hunger producing hormone (ghrelin). Thus, the patients feel easily satiety after the surgery and it helps them to reduce their body weight.


In this operation, a small gastric pouch of around 50 ml is created which is joined to a limb of intestine bypassing a total of 150-200 cm of small intestine. This helps in reducing the amount of food intake and also the absorption of the ingested food by the intestine.


This is one of the simplest bariatric surgeries to perform in which an adjustable silicon band is placed around the upper end of the stomach which helps to regulate food intake and provide a sense of satiety to the patient.


A relatively new procedure wherein a part of the stomach is sewn with non absorbable sutures to reduce its size. This is a very economical option for patients who cannot afford the previously mentioned procedures.
