In this procedure, a hollow band made of special material is placed around the stomach near its upper end, creating a small pouch and a narrow passage into the larger remainder of the stomach. The band is then inflated with a salt solution. It can be tightened or loosened over time to change the size of the passage by increasing or decreasing the amount of salt solution.

Here a small stomach pouch is created to restrict food intake. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). This bypass reduces the absorption of nutrients and thereby reduces the calorie intake.

This is a relatively new approach. It is the first component of the duodenal switch operation and involves removing the lateral 2/3rds of the stomach with a stapling device. It can be done laparoscopically ( keyhole surgery) but is not reversible. It basically leaves a stomach tube instead of a stomach sack.

These operations combine the removal or exclusion of 2/3rds of the stomach along with a long intestinal bypass, which significantly reduces the absorption of fat. The capacity to eat is greater than with the other operations, and the eventual weight loss is the best of all the operations, but if fatty foods are overeaten e.g. a hamburger and fries, then diarrhoea and foul flatus will result.

Intragastric Balloon is a non-surgical, non-pharmaceutical aid in the treatment of obesity. In conjunction with a supervised diet and behaviour modification program, it can help you achieve the health and aesthetic benefits associated with weight loss.
The instragastric balloon system consists of a soft, expandable balloon, the placement tube and a filling system so a physician can orally insert the weight loss aid.
Once inserted in the stomach, the empty balloon is filled with sterile saline. When full, the balloon is too large to pass into the bowel and will now float freely in the stomach.
