Gastric sleeve surgery (sleeve gastrectomy) does not reroute the digestive tract or intestines, making it a streamlined and physiologically natural procedure while providing substantial, long-term weight-loss and metabolic benefits.
How Gastric Sleeve Works
- Permanent Volume Reduction: Approximately 75% to 80% of the stomach along the greater curvature is removed laparoscopically, leaving a slender vertical tube holding roughly 100–150 ml.
- Hormonal Reset (Ghrelin Suppression): The excised fundus is the primary site of ghrelin (hunger hormone) synthesis. Its removal significantly curtails constant appetite and food cravings.
- Natural Digestion Preserved: Because the pyloric valve and small intestine remain completely intact, nutrients are absorbed naturally without dumping syndrome.
