bariatric surgeryPrograms, Clinics and Services

The Bariatric Surgery Department is proud to be one of the only sites in Canada that offers Gastric Bypass, Biliopancreatic Diversion with Duodenal Switch, Sleeve Gastrectomy and Revisional Surgery. Almost all surgery is performed laparoscopically.

Eligible patients include persons with a body mass index (BMI) over 40, or a BMI over 35 but with obesity related comorbidities, such as diabetes, sleep apnea, or high blood pressure. Patients may be required to undergo further investigations and we expect our patients to quit smoking prior to surgery.

Currently all procedures are performed laparoscopically (with small cuts) unless otherwise stated by your surgeon. All patients follow a carefully designed pathway and the Bariatric Surgery Department offers support throughout the preoperative, intraoperative and postoperative stages.

What to Expect

After you have attended an information session, you will be given an appointment with one of the surgeons. You will then finalize your decision regarding which bariatric surgery is right for you. Your surgeon will also explain the risks, benefits and alternatives to surgery. You will also meet the nurse and dietitian to further review all other important factors. Once the whole team agrees that you are a suitable candidate, a date for your surgery will be set. You must also attend a preoperative visit at the hospital, and you will usually be asked to take a special liquid diet for two weeks prior to your surgery.
