What is gastric sleeve surgery?
Gastric sleeve (sleeve gastrectomy) permanently shrinks the stomach to ~25% of its size by removing the larger portion, leaving a narrow, sleeve-shaped stomach. This makes patients feel full faster and eat less. Sometimes it’s done before gastric bypass in very obese patients. Unlike bypass, it doesn’t change the small intestine.
What happens during a gastric sleeve surgical procedure?
Gastric sleeve surgery is done laparoscopically through small incisions using a scope and surgical tools, causing less tissue damage and faster recovery. The stomach is reshaped with a stapler, incisions are closed, and bandages applied. The procedure usually takes under 90 minutes.
What risks are associated with sleeve gastrectomy?
After gastric sleeve surgery, the smaller stomach can cause nausea if patients overeat. Following post-op guidelines is crucial. Nutrient absorption may be slightly reduced, so supplements are often recommended to maintain proper nutrition.
Can the procedure be reversed?
No, sleeve gastrectomy permanently alters the shape of the stomach and it cannot be reversed.
