According to the Canadian Institute for Health Information (which tracks statistics about healthcare funding, usage and outcomes in Canada), the three most common bariatric surgical approaches offered in Canada are:
Adjustable Gastric Banding – This reversible procedure uses an adjustable band wrapped around the top of the stomach, which creates a small pouch that holds about one half cup of food. Adjusting the band increases or decreases the size of the pouch, which in turn increases or decreases the amount of food you can eat. Since this procedure has poor long term results, most surgeons have stopped performing this procedure.
Sleeve Gastrectomy – Here, surgeons will remove most of the stomach, leaving only a banana-sized vertical “sleeve” of it in place.
Gastric Bypass – A small stomach pouch is created using surgical staples, which also allows food to bypass some of the small intestine.
