Gastric Sleeve
Overview
Gastric sleeve surgery, medically known as sleeve gastrectomy, is a widely performed bariatric procedure designed to help people with obesity achieve significant and lasting weight loss. In this operation, a large portion of the stomach is surgically removed, creating a smaller, tube-shaped stomach or “sleeve.” This reduces the amount of food the stomach can hold and decreases hunger signals, supporting long-term weight loss and improvements in obesity-related health conditions.
What Is Gastric Sleeve Surgery?
During a gastric sleeve procedure, about 75–80% of the stomach is removed, leaving behind a narrow, banana-shaped sleeve. Because the stomach is smaller, patients feel full sooner with less food. In addition, the part of the stomach that produces the hunger hormone ghrelin is removed, which often leads to reduced appetite and cravings.
Gastric sleeve surgery does not involve bypassing the intestines, so it does not alter how nutrients are absorbed. Instead, it mainly restricts food intake and triggers hormonal changes that promote weight loss.
How the Procedure Works
Gastric sleeve surgery is usually performed using minimally invasive laparoscopic techniques, which involve small incisions and the use of a video camera (laparoscope). This approach typically results in less post-operative pain, shorter hospital stays, and faster recovery.
During the procedure:
- You are placed under general anesthesia.
Small incisions are made in the abdomen.
The surgeon removes the larger portion of the stomach, creating a narrow sleeve.
The remaining stomach is stapled and reshaped.
The incisions are closed, and the surgery is complete.
The operation generally takes about 30–60 minutes.
Benefits of Gastric Sleeve Surgery
Gastric sleeve surgery has helped many patients achieve meaningful weight loss and improve health outcomes. Common advantages include:
Recovery & Aftercare
Following surgery, patients typically stay in the hospital for 1–2 days for monitoring. In the first weeks, the diet progresses from clear liquids to soft foods and eventually to a balanced solid diet under clinical guidance.
Full recovery varies but many people return to normal activities within a few weeks. Ongoing follow-up with nutrition specialists and your bariatric care team helps support sustained weight loss and overall health. Regular exercise, balanced nutrition, and behavioral support remain vital components of long-term success.
