Gastric Sleeve Resection

Permanent weight loss surgery

Gastric sleeve resection is a type of weight loss surgery that is performed with the goal of permanently reducing the size of the stomach, which in turn can reduce sensations of hunger and increase a sense of fullness.


With a drastically smaller stomach pouch after surgery, many patients report they are satisfied with much smaller portions of food, and lose significant weight as a result of reduced caloric intake.


As with all bariatric surgery, patients must qualify for the procedure by carrying a body mass index (BMI) that is high enough to put their overall health at risk.

A weight loss first step

Some extremely overweight patients whose health may not allow a full vertical gastric bypass at the beginning of their weight loss opt to undergo gastric sleeve resection as a first step, helping them to lose enough weight initially that they qualify for more invasive gastric bypass surgery.


During the gastric sleeve resection procedure, the surgeon removes as much as 60 percent of the patient’s stomach, leaving a portion shaped like a tube, or “sleeve.”


Published scientific data suggests if patients who have a BMI greater than 50, gastric sleeve resection is just as effective as gastric bypass for the surgical treatment of weight loss. In addition, recently published research suggests that weight loss surgery may help treat Type 2 diabetes by changing the way food is metabolized in the gastrointestinal tract.
