What is Gastric Sleeve Surgery?
Gastric sleeve surgery, also known as sleeve gastrectomy or vertical sleeve gastrectomy (VSG), is a bariatric procedure that removes approximately 80% of the stomach, leaving a narrow, tube-shaped "sleeve" about the size of a banana.
The procedure permanently reduces stomach size, limiting the amount of food you can eat at one time. It also removes the part of the stomach that produces ghrelin, the hunger hormone, which significantly reduces appetite.
Unlike gastric bypass, the sleeve procedure doesn't involve rerouting the intestines, making it less complex whilst still delivering excellent weight loss results.
Expected Weight Loss Results
Most gastric sleeve patients lose 60-70% of their excess body weight within 12-18 months following surgery.
Individual results vary based on adherence to post-surgery diet, exercise recommendations, and lifestyle changes. Weight loss surgery is a tool, not a cure, and requires lifelong commitment.

What's Involved in the Gastric Sleeve Procedure
Step-by-Step Surgical Process
Anaesthesia
General anaesthesia is administered. You'll be completely asleep and pain-free throughout the 2-3 hour procedure.
Laparoscopic Incisions
Your surgeon makes 4-5 small incisions (5-12mm) in your abdomen to insert specialised laparoscopic instruments and a camera.
Stomach Division
Using a surgical stapler, approximately 80% of the stomach is divided vertically and removed from the body. This includes the section that produces the hunger hormone ghrelin.
Sleeve Formation
The remaining stomach is formed into a narrow, tube-shaped sleeve about the size and shape of a banana. The staple line is reinforced.
Completion
The surgeon inspects the staple line for leaks, removes instruments, and closes the small incisions with dissolvable sutures.

Common risks include staple line leak (less than 1%), bleeding, infection, and blood clots. The procedure has been performed successfully thousands of times in Australia with high safety standards. Your surgeon will discuss all risks during consultation.
How long does gastric sleeve recovery take?
Most gastric sleeve patients stay in hospital for 1-2 nights and can return to light activities within 1-2 weeks. Return to work typically occurs at 2-3 weeks for desk jobs, 4-6 weeks for physical work. Full recovery takes approximately 6 weeks. Diet progresses from liquid to solid foods over 6-8 weeks. See our detailed recovery timeline above.
Will private health insurance cover gastric sleeve surgery?
Most Australian private health insurers cover gastric sleeve surgery with appropriate hospital and extras cover (typically Gold level or higher). A 12-month waiting period applies for bariatric surgery. Medicare provides rebates for eligible patients. Out-of-pocket gap fees typically range from $5,000 to $12,000 depending on your insurer and surgeon. Check with your fund for specific coverage details.
How much weight will I lose after gastric sleeve?
Most gastric sleeve patients lose 60-70% of their excess body weight within 12-18 months. For example, someone 50kg overweight may lose 30-35kg. Weight loss is most rapid in the first 3-6 months. Individual results vary based on adherence to diet, exercise, and lifestyle changes. Long-term success requires permanent lifestyle modifications and ongoing medical support.
What can I eat after gastric sleeve surgery?
After gastric sleeve surgery, you'll progress through diet stages: Week 1-2: Clear liquids only. Week 3-4: Full liquids and protein shakes. Week 5-6: Pureed and soft foods. Week 7+: Gradual introduction of solid foods. Long-term, focus on protein-rich foods, vegetables, and small portions (3-6 small meals daily). Avoid high-sugar foods, carbonated drinks, and eating too quickly.
Can gastric sleeve be reversed?
No, gastric sleeve surgery is permanent and cannot be reversed. Approximately 80% of your stomach is permanently removed during the procedure. However, if complications occur or additional weight loss is needed, revision surgery to gastric bypass is possible. It's crucial to be certain about your decision before proceeding with gastric sleeve surgery.
What's the difference between gastric sleeve and gastric bypass?
Gastric sleeve removes 80% of the stomach, creating a tube-shaped stomach. It's simpler, with faster recovery, achieving 60-70% excess weight loss. Gastric bypass creates a small stomach pouch and reroutes the intestine, achieving 70-80% weight loss and better results for diabetes. Bypass has longer recovery and higher complication risk.
