WEIGHT-LOSS SURGERY Treatment Options

Bariatric Surgery

Three Common Types of Procedures

Make informed decisions about your care. Take your time to learn about the various weight loss strategies.

  • Restrictive techniques make your stomach smaller.
  • Malabsorptive techniques decrease your ability to absorb nutrients from food.

The three common types of weight-loss procedures use one or both of these techniques.

  • Sleeve gastrectomy is a restrictive procedure. The surgeon removes two-thirds of the stomach, which provides a quicker sense of fullness and decreased appetite.  
  • Roux-en-Y gastric bypass is both a restrictive and a malabsorptive procedure. The surgeon decreases the size of your stomach and causes food to go only through part of the small intestines.
  • Adjustable gastric banding is a restrictive procedure. The surgeon places a band around the top of the stomach. This limits food intake, thus encouraging weight loss. 

Keep in mind that any effective weight loss program should also include a combination of diet change, increased physical activity, and behavior therapy.

Sleeve Gastrectomy

Sleeve Gastrectomy

This procedure is a restrictive procedure that changes the shape and size of the stomach. The surgeon removes approximately two-thirds of the stomach; thus, the stomach is reshaped into a long tube, or “sleeve.” After the procedure, the stomach is about the size and shape of a banana and resembles a sleeve.

Why Choose Sleeve Gastrectomy

The procedure:

  • restricts food intake by allowing only a small amount of food to be consumed in a single sitting, providing a quicker sense of fullness and decreased appetite
  • does not require the surgeon to implant a foreign body such as the band used in gastric banding
  • decreases the secretion of the hormone ghrelin, which is responsible for the feeling of satiety (fullness)
  • initially decreases the body weight of the severely obese patient to prepare this patient for a staged procedure or other surgery at a later time

Roux-en-Y Gastric Bypass

Adjustable Gastric Banding

OTHER PROCEDURES

Single Anastomosis Duodenal Switch

The single anastomosis duodenal switch works by creating a sleeve gastrectomy where the stomach is reduced and narrowed like a tube for restriction and hunger control. In the second step, the intestines are rerouted similar to a gastric bypass to reduce the surface for food absorption. Specifically, the middle part of the small bowel is excluded from food transit. After this procedure, the food travels from the small new stomach to the distal intestine bypassing a long segment of the small bowel, which remains in the abdominal cavity, but is excluded from the food circulation. These anatomical changes decrease oral intake and reduce the absorption of the nutrients and calories eaten.1
