Gastric Sleeve

A sleeve gastrectomy is the most common weight loss operation in Australia. About three quarters of the stomach is removed by keyhole (laparoscopic) surgery, leaving a narrow tube similar to the size and shape of a banana.

How It Works

The smaller stomach holds less and you feel full sooner. Removing the part of the stomach that makes most of the hunger hormone ghrelin also changes your appetite. It isn't just about restriction: the hormone signals that control hunger and fullness change as well, which is why many people find they simply feel less hungry.

Who It Suits

A sleeve may suit you if you are living with obesity and related health problems, and you don't have significant reflux or a large hiatus hernia. It doesn't involve rerouting the bowel, which some people prefer. It has a lower risk of early complications than a bypass, but reflux is more common.

Things to Consider

  • Reflux. Reflux can start or worsen (and in some cases improve) after a sleeve. You will go home on anti-acid medication for three months, and some people need to continue it.
  • Irreversible. It can't be reversed, because part of the stomach is removed.
  • Supplements. You will need vitamin and mineral supplements and regular blood tests long term.
  • Weight regain. Some people regain weight after this operation, which is why ongoing follow-up with Dr Lourensz and your dietitian matters.

Pregnancy Planning

Pregnancy is not recommended for 1 to 2 years after weight loss (bariatric) surgery. Discuss pregnancy plans, reliable contraception and nutritional follow-up before surgery.

The Operation and Recovery

The operation is done by keyhole (laparoscopic) surgery. Most people stay in hospital for one night. Afterwards you progress your diet over several weeks, starting with fluids, with support from Dietitian Louise Becroft.

Risks

Risks include a leak from the staple line, bleeding, blood clots, narrowing (stricturing) of the sleeve, reflux, nutritional deficiencies and the need for further surgery. Dr Lourensz will go through your own risks in detail and answer your questions.
