Gastric Sleeve, also called a Sleeve Gastrectomy, is a weight loss surgery in which the large part of the stomach is surgically removed. This results in a new stomach which is roughly the size and shape of a banana. Like other bariatric surgeries, the impact of the Gastric Sleeve helps to reduce hunger which in return helps patients to decrease the number of calories they consume, helping them to reach a healthy weight and promote healthy eating habits.

With a smaller stomach pouch, eating just a small amount of food will satisfy hunger and promote feelings of fullness.

The surgery is usually done using a small camera that is placed in the stomach. This type of surgery is called laparoscopy. The camera is called a laparoscope and allows for the surgeon to see inside your stomach.

In this surgery:

  • Your Surgeon makes 2 to 5 small cuts (incisions) in the stomach. The scope and instruments needed to perform the surgery are inserted through the cuts.
  • The camera is connected to a video monitor in the operating room and allows the Surgeon to view inside the stomach during the operation. The Surgeon removes most of the stomach and the remaining portions are joined together using surgical staples. This creates a long vertical tube or banana-shaped stomach.
  • The surgery does not involve cutting or altering the sphincter muscles that allow food to enter or leave the stomach.
  • Last, the scope and other tools are removed and the cuts are sutured closed.


Q: What kind of results should I expect?

A: The gastric sleeve has excellent weight loss and obesity related disease improvement potential. While individual results vary, the average patient loses up to 70% of their excess body weight. Patients report improvement or elimination of their obesity related diseases such as high blood pressure, etc.

Q: Are all sleeves performed laparoscopically

A: Most of gastric sleeve procedures are performed as a minimally invasive procedure. However, if patient specific circumstances dictate concern, a Surgeon may suggest an open procedure as being safer or more effective, but is a very rare occurrence.

Q: Who is an ideal candidate for a gastric sleeve?


  • Individuals with BMI >40 or BMI >35 with other co-morbidities
  • Complex surgical histories
  • Those fearful of potential complications from a gastric bypass
  • Individuals who wish to avoid potential nutritional deficits
  • Individuals who might be interested in the procedure, but prefer to avoid the foreign body concern of the band.

Q: Will my stomach stretch back to a normal size?

A: The stomach will not stretch back to its original size. Patients who continue to overeat and lead sedentary lifestyles following surgery risk increasing their new stomach size and weight.

Q: How quickly will I lose my excess weight?

A: This is different for every individual. Every person responds differently to weight loss surgery. With the Gastric sleeve procedure, the common patient reports losing around 50-60% of excess body weight loss in approximately 2 years.

Real Patients, Real Results


“ORBERA® made the difference when nothing else could.”

Before ORBERA®, Mary wasn’t happy with herself. She didn’t enjoy how she looked or how she felt. She didn’t even recognize who she was anymore. After some research, Mary knew that ORBERA® was for her. Now, she’s 43 lbs lighter and happier than ever.


“Make the commitment and be sure that you want to do it.”

For me the toughest part was making the decision to finally commit and say I’m going to do this. I would give anyone considering LAP-BAND® the same advice that my colleagues gave me, to make the commitment and be sure that you want to do it.
