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 behaviour 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
