This represents an almost four-fold increase over a six-year period, due largely to increased capacity for bariatric surgery in Ontario. The most commonly performed procedures have changed over time, and they continue to vary across Canada.

Adjustable Gastric Banding
A procedure in which an adjustable band is placed around the upper portion of the stomach, thus reducing the overall size of the stomach.
Sleeve Gastrectomy
A procedure in which about 80% to 85% of the stomach is removed, thus creating a “sleeve” of the stomach, extending from the esophagus to the duodenum.
Gastric Bypass
A procedure where the size of the stomach is reduced and part of the small intestine is bypassed.
