Gastric Sleeve

At SmartShape™ Weight Loss Centre, gastric sleeve surgery has helped thousands of people from Toronto, Mississauga, and throughout Ontario, Quebec, British Columbia, and Alberta, Canada, experience significant and sustained weight loss. Our primary goal is to ensure you have all the information you need to make a confident and informed decision when determining if a gastric sleeve procedure is right for you.

What Is a Gastric Sleeve Procedure?

The gastric sleeve procedure is performed laparoscopically in about 60 to 90 minutes. The surgery involves removing a portion of the stomach, leaving a small sleeve or tube of the stomach behind. This revised stomach is about the size and shape of a banana.

How Does a Gastric Sleeve Work?

The gastric sleeve procedure is so effective for sustained weight loss for the following reasons:

  • You feel satisfied with smaller portions of food. When you eat, the small sleeve or pouch of the stomach that’s left behind fills with each bite of food, signalling to the brain that you are full. Because the stomach is smaller, your brain thinks you have eaten a larger portion of food than you actually have.
  • Your hunger level is reduced. The surgery removes the main part of the stomach that produces a hunger hormone called ghrelin, helping you to go longer between meals.

How Long Does It Take To Recover From Gastric Sleeve Surgery?

Most gastric sleeve patients are ready to return to their daily activities, including work, within about 10 days. Strenuous activity can be resumed as directed in about 3 to 4 weeks.

FAQs About the Gastric Sleeve Procedure at SmartShape

Will I feel pain after gastric sleeve surgery?

The gastric sleeve 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 stays, faster recovery, and reduced risks of infection.

During the first week after the procedure, expect to 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.

Do I need to follow a special diet in the weeks immediately following the procedure?

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 rush the process of increasing your food intake. Always continue to follow the diet that has been provided to you.

Can I resume physical activity after the gastric sleeve procedure?

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 2 weeks.

Can the gastric sleeve procedure be reversed?

No, this procedure cannot be reversed. However, the part of the stomach that is removed does not affect the overall function of the stomach. Digestion and absorption of nutrients are not changed with the gastric sleeve procedure.
