Surgical Program

Patients are assessed and recommended for bariatric surgery as appropriate. The surgical procedure most commonly performed is Roux-en-Y gastric bypass, but some patients may require gastric sleeve or other less commonly used procedures. After completing the assessment process, patients recommended for surgery will have it performed at either Hotel Dieu Hospital in Kingston or at a designated bariatric surgical site in Toronto.

Before being considered for elective bariatric surgery, patients must undergo a comprehensive assessment and screening process that adheres to strict Ontario Bariatric Network criteria. Conducted by an interprofessional team, this process ensures that patients are well prepared and that gastric bypass surgery is the best option for them.
