What is bariatric surgery?

Bariatric surgery is a laparoscopic surgery (micro-surgery), wherein, alterations are made in the stomach and/or intestines of the suffering person. Bariatric surgery is very safe and recovery after surgery is quick, in fact, the patient is made to walk, the same day as surgery. Following surgery, the patient loses weight at a rapid pace in the next few months. The improvement of diabetes is even more dramatic, with most patients having normal blood sugar within the first few days of surgery. There are many causes for this improvement like changes intestinal hormones which leads to increased production of insulin, restriction of food intake and weight loss which reduces insulin resistance. No other form of treatment can act by so many mechanisms. That is why bariatric surgery is the most effective treatment of diabetes in obese individuals.

Types of Bariatric surgery?

Laparoscopic Sleeve Gastrectomy (LSG)
This procedures involves reduction of size of the stomach making it tube like the process. This is a restrictive procedures achieving excellent weight loss. It is better suited for patients who are young with less severe form of obesity with fewer associated diseases.

Laparoscopic Roux-en-Y Gastric Bypass (RYGB)
This procedures involves creation of a small stomach pouch along with bypass of a small segment of intestines. Thus, this procedure causes both restriction of food intake, as well as, reduced absorption of food. This procedure is more suitable for higher BMI patients and those with severe diabetes.

Mini Gastric Bypass / One Anastomosis Gastric Bypass (MGB/OAGB)
This procedure involves creation of a larger stomach pouch with bypass of a segment of intestines. This procedures achieves excellent weight loss with good resolution of diabetes.

Duodeno-jejunal Bypass (DJB)
Another type of bypass along with a sleeve gastrectomy. This procedure is more suited for super-obese and patients with uncontrolled diabetes.

Single Incision (SILS) Bariatric surgery

Types of Endoscopic Bariatric procedures

Intra-gastric Balloon (IGB)
Endoscopic placement of silicon balloon in the stomach to restrict food intake.

Endoscopic Sleeve Gastroplasty (ESG)
Endoscopic plication of stomach reducing its volume causing reduced food intake
