Sleeve Gastrectomy
A weight-loss surgery that removes about 80% of the stomach, reducing food intake and hunger hormone production.
Plain English
Patient-Friendly Explanation
Sleeve gastrectomy is a weight-loss surgery where about 80% of your stomach is removed, leaving a tube-shaped "sleeve." This smaller stomach holds less food and produces less of the hunger hormone ghrelin, helping you feel full sooner and eat less.
Medical
Clinical Definition
Sleeve gastrectomy (SG) is a restrictive bariatric procedure in which approximately 75–80% of the stomach is resected along the greater curvature, creating a narrow gastric tube. The procedure reduces gastric volume to 60–150 mL and induces significant reductions in ghrelin secretion, contributing to both mechanical restriction and neurohormonal appetite modulation.
