You should speak to a specialist if you are struggling to lose weight and have tried other forms of weight loss strategies, such as dieting and exercise and weight loss medicines (as advised by your doctor) and/or have a BMI of 40 or above.


How is gastric sleeve surgery performed?

In the weeks leading up to your surgery, you may be required to start a physical activity program and to stop any tobacco use. Right before your procedure, you may have restrictions on eating and drinking and which medications you can take.

Sleeve gastrectomy is typically performed laparoscopically, which involves inserting small instruments through multiple small incisions in the upper abdomen.

You are given general anaesthesia before your surgery begins. To perform a sleeve gastrectomy, the surgeon creates a narrow sleeve by stapling the stomach vertically and removing the larger, curved part of the stomach.

The surgery usually takes one to two hours.

What is the recovery for gastric sleeve surgery?

Most people recover fairly quickly from a gastric sleeve and feel ready to go back to normal activities after a few weeks. After sleeve gastrectomy, your diet begins with sugar-free, noncarbonated liquids for the first seven days, and then progresses to pureed foods for three weeks and finally to regular foods approximately four weeks after your surgery.

You may experience changes as your body reacts to the rapid weight loss in the first three to six months after sleeve gastrectomy, including: body aches, feeling tired, feeling cold, dry skin, air thinning and hair loss and mood changes
