Gastric Sleeve Surgery

Gastric sleeve

A gastric sleeve is sometimes used to treat obesity. Your surgeon performs a laparoscopic sleeve gastrectomy, which is an effective and minimally invasive bariatric surgery.

What is gastric sleeve surgery?

Laparoscopic sleeve gastrectomy – simply known as a gastric sleeve surgery – is a minimally invasive bariatric surgery used in the treatment of obesity and is now being offered as a stand-alone procedure for morbidly obese patients. Patients are carefully selected for a lap sleeve, and it is relatively safe with minimal risks even for high-risk patients. Note that vitamin and mineral supplements must be used over longer periods following the surgery.


The gastric sleeve procedure removes the lateral two-thirds of the stomach, which is reduced with a stapling device. It is usually done laparoscopically in order to be as minimally invasive as possible, and is not reversible. The procedure basically leaves a stomach tube instead of a stomach pouch.

The outcome of gastric sleeve surgery

The results of weight loss surgeries vary from one patient to another, and it is important to remember that the results can also be attributed to various factors such as age, weight before surgery, exercise level, metabolism, and eating habits. Generally speaking, patients can lose 33% to 83% of excess body weight. Most importantly, it depends on your overall commitment to a new lifestyle, which is ultimately what will help you lose weight, feel better, and improve your overall quality of life.

Funding access

Some health funds will cover lap sleeve surgery. Please check with your health plans for details.
