Weight loss surgery types

Weight loss surgery falls into three basic categories: restrictive surgery, malabsorptive surgery and mixed type surgery.

Restrictive surgery:
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. Restrictive weight loss surgery works by reducing the amount of food consumed at one time. It does not, however, interfere with the normal digestion of food.

This type of procedure includes:

  • Vertical banded gastroplasty
  • Adjustable Gastric Banding
  • Sleeve Gastrectomy
  • Gastric Plication

Malabsorptive surgery:
Malabsorptive procedures alter digestion, thus causing the food to be poorly digested and incompletely absorbed so that it is eliminated in the stool partially undigested.

This type of procedure includes:

  • Biliopancreatic diversion.

Mixed type surgery (Restrictive and Malabsorptive):
These operations combine stomach restriction with a partial bypass of the small intestine. These procedures create a direct connection from the stomach to the lower segment of the small intestine, literally bypassing portions of the digestive tract that absorb calories and nutrients. A combination of restrictive and malabsorptive procedures tend to produce more weight loss than either procedure does on its own.

This type of procedure includes:

  • Roux-en-Y Gastric Bypass (RYGBP)
  • Mini Gastric Bypass
  • Sleeve gastrectomy with duodenal switch

Adjustable Gastric Banding

Gastric banding is an adjustable gastric band that alters the anatomy of the stomach to help you reduce your food intake.

It is performed laparoscopically, meaning that the surgeon makes small incisions as opposed to one large incision.


Sleeve Gastrectomy?

Sleeve gastrectomy, or vertical sleeve gastrectomy, is one of the relatively newer types of weight loss surgery.

This surgery can also be referred to medically as gastric sleeve resection, gastric sleeve surgery or tube gastrectomy.


Gastric Bypass

Gastric bypass (Roux-en-Y Gastric Bypass) is regarded internationally as the “gold standard” of weight loss surgery designed to reduce your food intake if you have tried and failed to lose weight through diet and exercise. Follow up to 15 years after surgery has shown patients maintain weight loss after gastric bypass surgery.
