You have tried your best to permanently control your weight with no success and are now considering  weight loss surgery also known as bariatric or metabolic surgery.

Here are the facts?

  1. Morbid obesity is a chronic condition with many associated diseases.
  2. Diets don’t work in the long run, but you probably know this already.
  3. Medical experts agree that weight loss surgery or bariatric surgery produces long term weight loss.
  4. Medical experts agree that weight loss surgery or bariatric surgery improves most obesity-associated diseases including: Type 2 diabetes, high blood pressure, sleep apnea, high cholesterol/lipids and stress incontinence.
  5. Medical experts agree that weight loss surgery or bariatric surgery  reduces the risk of premature death.

Which weight loss surgery should you have?

  1. You have a choice between the Gastric Bypass (roux-en-Y gastric bypass) or  the Gastric Sleeve ( Vertical Sleeve Gastrectomy).
  2. We recommend the “gold standard” gastric bypass in most cases because of solid results up to 25 years after the surgery.
  3. We do not recommend adjustable gastric band surgery because of complications 3+ years after the surgery.
  4. We do not recommend the gastric balloon as it is a temporary procedure, just like the diets you tried and failed.
  5. The duodenal switch is reserved for special cases e.g. over 450 lbs or 220 kg weights.
  6. There are many experimental procedures that we do not yet recommend because the long term results are not known (eg. single anastomosis bypass, ilea interposition etc.).

When can you get the surgery?

  1. We can complete your surgery in  4-6 weeks from the time we receive your completed patient questionnaire.
  2. If you suffer from certain obesity associated diseases such as heart disease, or lung disease, it may take 4-6 weeks  longer – for your own safety. We need to ‘optimize’ your health and minimize the risks.
  3. You also get to chose the time that suits you and you will not be cancelled due to emergencies.

What does the surgery cost?

  1. We are a private facility and our surgeons work outside of Medicare (non participating physicians within the meaning of the health act).
  2. This means that you (or your insurance) must pay for all the costs.
  3. You pay one fee and we provide turn-key service for you.

How safe is this surgery?
We present our published experience including the data from our private hospital.


Our Office Location for preoperative and postoperative visits and care 


Our Private Hospital, Centre du Chirurgie Metropolitain,  where all our surgeries are performed 

CMCP outside view

We are fortunate to have access to a licensed, fully accredited hospital facility in Montreal, Canada with highly trained staff and the latest laparoscopic equipment for bariatric surgery .

This allows us to  admit and care for our patients for 1-2 days after surgery (depending on the procedure) to ensure their safety.

As an added precaution, we have a direct “service corridor” with the McGill University Health Center (MGH Pavillion), a  tertiary care bariatric surgery center,where patients can be transferred if the need for intensive care arises due to rare complications of leak, pulmonary embolus or myocardial infaction (< 2% chance).
