Achievements & Roles
Procedure Information
Gastric Sleeve (Laparoscopic Sleeve Gastrectomy)60–70% excess weight loss within 12–18 months▼
The procedure involves removing approximately 70–80% of the stomach, leaving a narrow gastric "sleeve". This reduces food intake and significantly lowers hunger by decreasing production of the hormone ghrelin. Gastric Sleeve surgery does not alter the normal digestive pathway, making it a widely accepted and effective treatment for obesity and related metabolic conditions.
Gastric Bypass (Roux-en-Y & Single Loop)70–80% excess weight loss within 12–18 months▼
Gastric Bypass surgery is a highly effective bariatric procedure that combines restriction of food intake with changes to digestion and nutrient absorption. The procedure involves creating a small stomach pouch and rerouting part of the small intestine. This reduces the amount of food that can be eaten and alters how calories are absorbed, resulting in significant and sustained weight loss.

Revision Bariatric Surgery▼
Additional procedures may be required if previous surgery has not achieved the desired outcome or complications develop. Options may include conversion to Gastric Bypass Surgery or other tailored procedures following imaging and endoscopic assessment. Revision procedures are more complex and require specialist expertise and careful patient selection.
