Sleeve gastrectomy

  • During a sleeve gastrectomy, the stomach will be stapled and then separated, resulting in a long, tube-shaped stomach. The other 80 percent of the stomach is then removed. This new smaller stomach limits the amount of food that can be eaten during a meal, which leads to weight loss. Unlike the Roux-en-Y procedure, the sleeve gastrectomy does not bypass a portion of the intestines. This may make it easier to take medications. The rate of weight loss may be slightly slower than Roux-en-Y, but is more rapid than the adjustable band.


    • No re-routing of intestine
    • Moderately rapid weight loss
    • Ease in taking medications


    • Potentially slower reintroduction of solid foods
    • Less long-term outcome research available
