How it works
Laparoscopic Gastric sleeve surgery is a minimally invasive procedure that removes approximately 75–80% of the stomach, leaving a smaller, sleeve-shaped stomach. This results in:
- Reduced food intake and calorie consumption.
- Decreased hunger due to altered levels of hunger hormones, like ghrelin, GLP-1 etc.
- Significant and sustainable weight loss, often up to 60-70% of excess weight.
