What is Gastric Sleeve Surgery?
Gastric sleeve surgery involves removing approximately 75-80% of the stomach, creating a sleeve-shaped pouch roughly the size of a banana. This restrictive procedure works by:
- Reducing stomach capacity from ~1500ml to ~100-150ml
- Removing ghrelin-producing cells that stimulate hunger
- Creating early satiety with smaller meal portions
- Improving metabolic hormones for diabetes control
Unlike gastric bypass, sleeve gastrectomy doesn't involve intestinal rerouting, making it a simpler procedure with fewer long-term complications. At our bariatric surgery center in Ahmedabad, we've seen patients achieve 60-70% excess weight loss within 12-18 months.
