What is weight loss surgery?

It refers to the various gastrointestinal surgical procedures available to help the severely obese patients lose weight. It is the most effective method to reduce weight and maintain weight loss in the severely obese. Obesity related health disorders such as diabetes mellitus and high blood pressure may be improved or resolved with weight loss surgery.

Who is eligible for weight loss surgery?

Patients with a Body mass index (BMI) of > 37.5 kg/m2 and BMI > 32.5 kg/m2 (for Asians) with significant obesity related co-morbidities. They have failed non-surgical treatment (such as diet, exercise and drug treatment), are fit for surgery and agree to lifelong follow up and lifestyle changes.

What are the options?

They include adjustable gastric banding, sleeve gastrectomy and roux-en-Y gastric bypass.

1. Adjustable gastric banding (AGB) is one of the most frequently performed restrictive operation. A collar of silicone containing an inflatable bladder is placed around the upper stomach. Inflation is carried out by introducing saline via a special needle into a subcutaneous reservoir (port). It induces an early satiety and thereby decreases food intake. It also slows the passage of food from the upper pouch to the lower part of the stomach. Patients who undergo adjustable gastric banding can lose 50-60% of their excess body weight.   WeightLossSurgery1 
2. In sleeve gastrectomy, the stomach is reduced to about 15% of its original size. It is a purely restrictive operation and it eliminates the need of having to insert a foreign body. However, this procedure does involve stomach stapling and therefore leaks and other complications related to stapling may occur. It is also not reversible.  


3. Gastric bypass is a procedure that limits food intake and reduces the absorption of nutrients. The operation includes forming a small stomach pouch and a small bowel bypass. It has excellent and durable results with low morbidity and mortality rates.  


Most of the bariatric procedures can be performed laparoscopically. The clinical advantages of laparoscopic procedures are the reduction in postoperative pain, lower rate of wound-related complications, and quicker recovery.
