Sleeve gastrectomy is a surgical weight-loss procedure in which the stomach is reduced to about 25% of its original size, by surgical removal of a large portion of the stomach along the greater curvature. The result is a sleeve or tube like structure.
Gastric Sleeve Surgery reduces the size of the stomach, by up to 85%, and:
- Restricts food intake
- Reduces certain hormones that create food cravings (due to the removal of the excess stomach portion)
- Is less invasive than gastric bypass
- Requires a less restrictive post surgery diet
- Does not implement a foreign device to the body
- Does not require cutting or alteration of the intestines
Today, sleeve gastrectomy is the fastest growing weight loss surgery option in North America. In many cases, but not all, sleeve gastrectomy is as effective as gastric bypass surgery, including weight independent benefits on glucose homeostasis.
