Sleeve Gastrectomy

Sleeve gastrectomy removes approximately 75–80% of the stomach, creating a narrow, sleeve-shaped tube. This restricts food intake and significantly reduces levels of the hunger hormone ghrelin, making it easier to maintain a reduced calorie intake long-term.

It is the most widely performed bariatric procedure globally and delivers average excess weight loss of 60–70% at 12–18 months. It does not involve rerouting the intestine, keeping surgical complexity lower than a bypass.

Key Benefits

• Average excess weight loss of 60–70% at 12–18 months
• Reduction in hunger hormone ghrelin in addition to restriction
• No intestinal rerouting — simpler than gastric bypass
• Significant improvement in diabetes, blood pressure and sleep apnoea

Is This Treatment Right For You?

• Adults with BMI ≥35 who meet bariatric surgery criteria
• Patients wanting a simpler procedure than gastric bypass
• Those without severe acid reflux (bypass may be preferred for GERD)
