How it Works?	Restrictive	Restrictive	Restrictive + malabsorptive	Restrictive + malabsorptive
How is it done?	A silicone band with an inflatable balloon is implanted around the top of the stomach to restrict food intake. This creates a small pouch (15-30 ml) and a narrow passage to the lower stomach.	85 % of the stomach is removed so that it takes the shape of a tube or sleeve (75-125 ml).	A small new stomach pouch (15-30 ml) is created, restricting the amount of food that can be eaten. The stomach and about one meter of the small intestine are bypassed.	A small new stomach pouch (50 ml) is created, restricting the amount of food that can be eaten. The stomach and about two meters of the small intestine are bypassed.

Weight loss surgery types

Operations that reduce the stomach size or obstruct the pathway of food are known as restrictive surgery because they restrict the amount of food the stomach can hold. When you feel full, you are more likely to have reduced feelings of hunger and will no longer feel deprived.
