The mini gastric bypass procedure is a modern alternative to the traditional Roux-en-Y gastric bypass procedure for weight loss patients from Toronto, Mississauga, and other Ontario cities, Alberta, Quebec, and throughout Canada.
On average, a patient who has the mini gastric bypass procedure will lose up to 75% of their excess weight and most of that loss will occur in the first year.
The mini gastric bypass is performed laparoscopically at our surgery centre in Toronto. It’s a two-part procedure that divides approximately 25% of the stomach from the rest of the stomach. The remaining section is called a “gastric pouch” and it is then joined to the small intestine above a new surgical connection. After surgery, the majority of the stomach and approximately one-third of the small intestine is ‘bypassed’—meaning it is not involved in the digestion or absorption of the food you eat.
The mini gastric bypass procedure works in two ways. First, the small stomach pouch fills quickly, sending signals to the brain that you feel satisfied and comfortable with smaller portions of food. Second, the mini gastric bypass bypasses a section of the intestine so absorption of the food you do eat is reduced.
Patients are typically ready to return to work and regular light activity within about 10 days but delay strenuous activity for about 3 to 4 weeks. You will need to stay overnight in the hospital after mini gastric bypass surgery before returning home. We provide 24/7 after-hours support and a follow-up consultation with your surgeon as needed.

For safety and success after mini gastric bypass surgery, patients must commit to certain changes in their lifestyle and eating habits. Potential drawbacks of mini gastric bypass surgery include:
The mini gastric bypass procedure is performed laparoscopically which is a surgical technique where only small incisions are made. Laparoscopic surgery is a low-risk, minimally invasive technique with many benefits including smaller surgical scars, less pain, shorter hospital stay, faster recovery and reduced risks of infection.
During the first week after the procedure, you will feel some pain. The discomfort is usually restricted to the laparoscopic port sites and can be managed with oral pain medication. You may also experience mild “gas pain” that settles in a couple of days. Your doctor will give you instructions regarding pain management.
Following the procedure, you will be on a liquid-only diet. After a few days, you will be ready to begin trying some thicker liquids. The SmartShape team will explain when and how to increase the consistency of the food you eat during the first few weeks. You will likely be on solid food 3 to 4 weeks after your procedure. It is important you do not to rush the process of increasing your food intake. Always continue to follow the diet that has been provided to you.

We recommend that you start walking up to 30 minutes per day as soon as you are able. However, strenuous exercise is not recommended until 3 to 4 weeks after your procedure. We recommend that you do not lift more than 10 to 15 pounds for at least two weeks.
Although the mini gastric bypass procedure should be considered permanent, it can be reversed with another surgical procedure. This would be very uncommon and would likely lead to weight regain, however it is possible. This is different from the Roux-en-Y gastric bypass which is very difficult, if not impossible, to reverse.
While weight gain is common after weight loss through dieting alone, most patients experience long-term weight loss after mini gastric bypass surgery.
Bariatric surgery has emerged as an innovative alternative option in the management of Type 2 diabetes. Many 5-year studies are showing that the mini gastric bypass, as well as other bariatric surgeries, showing that bariatric surgery leads to a profound and durable resolution of Type 2 diabetes.
These procedures can result in sustained body weight loss and significant improvement in obesity-related comorbidities. Surgical weight loss procedures are recognized by Diabetes Canada to lead to significant and sustained weight loss and remission of Type 2 diabetes.
The mini gastric bypass procedure often leads to more rapid remission of Type 2 diabetes due to hormonal changes that occur as a result of food not passing through the first part of the small bowel. For this reason, SmartShape surgeons may suggest the mini gastric bypass procedure if you have Type 2 diabetes.
The mini gastric bypass is both safe and effective. There is just one anastomosis (join) of the intestine to the stomach, which differs from the Roux-en-Y gastric bypass which has two anastomoses. The single anastomosis reduces the risk of complications including hernias, leakage and bleeding. The mini gastric bypass procedure requires only one night’s stay in hospital.
The mini gastric bypass procedure was developed in 1997 with the goal of duplicating the excellent weight loss results of traditional Roux-en-Y gastric bypass surgery while at the same time simplifying the procedure, shortening the operating times and reducing complications. For these reasons the mini gastric bypass is gaining in popularity as the modern alternative to Roux-en-Y gastric bypass.
After the mini gastric bypass it will be necessary for you to take some specially chosen supplements on a daily basis. These supplements will ensure that you do not become deficient in some important nutrients such as iron, calcium, and some B vitamins.
Yes, it is safe to become pregnant after receiving the mini gastric bypass procedure, although it is wise to wait a number of months. In addition, losing weight improves your fertility and makes pregnancy safer for both you and the baby.
