Sleeve Gastrectomy


Sleeve Gastrectomy

The sleeve gastrectomy (also known as the gastric sleeve) is the most commonly performed bariatric surgery in the past decade.
It involves creating a much smaller stomach that limits the amount of food you can eat and that reduces the sensation of hunger.
Weight loss outcomes have been proven to be very good in the long-term when patients comply with the medical, nutrition, and lifestyle recommendations.

How it works

The sleeve gastrectomy works in a few different ways to promote weight loss:
A small ‘banana-shaped’ stomach is created to limit the amount of food you can eat at once.
The part of the stomach that secretes the hunger hormone (ghrelin) is removed, so you will experience a decrease in hunger. As well, other hormones will increase to improve diabetes.


You can expect to lose about 60% of your excess weight by 1 year after surgery with a much higher likelihood of keeping the weight off for many years to come. However, this will require you to follow the medical, nutrition, and lifestyle advice recommended by our medical team, including the surgeon, nurse, and dietitian.
In addition to weight loss, you will feel and experience and improvement in any obesity-related health conditions you may have, such as improved or resolved diabetes, improved cholesterol levels, improved blood pressure, less joint and back pain, and improved airway function (asthma and/or sleep apnea). Research has also shown a lower risk of developing obesity-related cancer after having bariatric surgery, and people who have surgery live longer than those who do not. In addition, women may also experience an improvement in fertility.
Disclaimer: Individual results may vary.

Advantages and Disadvantages

Technically this is a more simple surgery than the gastric bypass.
Effective weight loss outcomes and improvement of obesity-related health conditions.
No dumping syndrome.
Lower risk of vitamin and minerals deficiencies than the gastric bypass, however patients will still need to be on several vitamins/minerals for life.
The surgery is not reversible which means you will be bound to this smaller stomach for life.
Can worsen or create new heartburn issues.
There is less impact on the metabolism than the gastric bypass.

How it’s performed

The surgeon will make 5 small incisions on your abdomen to allow entry for the laparoscopic camera and instruments to perform the surgery. This technique reduces the risk of infection, recovery time, and pain.
The surgeon will remove about 80% of your stomach and your remaining stomach will be stapled to allow the tissue to hold together. The smaller stomach will prevent you from eating large amounts.
