 What We Do

Our goal is to help our patients achieve long-term weight loss and improve their quality of life and day-to-day functioning through surgery and sustained lifestyle changes. Our comprehensive program offers medical and surgical care, nutritional education and counseling and psychological and social support.

Patients who are interested in and may be eligible for bariatric surgery attend a series of assessment and education sessions to help our team determine if the patient will be a suitable candidate for bariatric surgery. Patients who undergo bariatric surgery also receive close follow-up care over a period of at least 1 year after their surgery. All services are covered by OHIP.

All patients referred to our clinic by the Ontario Bariatric Registry come to Toronto ​Western Hospital​ for assessment and education appointments.

Types of Surgery Performed

  • Gastric bypass (also called Roux-en-Y gastric bypass): Creating a small stomach pouch out of a portion of the stomach and attaching it directly to the small intestine.
  • Sleeve gastrectomy (also called vertical sleeve gastrectomy): Creating a small stomach pouch without affecting the small intestine. We perform this procedure in specific situations, as determined by your surgeon.

We perform both of these procedures using laparoscopic or minimally invasive surgery that involves small incisions in the abdomen.​​​​
