Advantages & Disadvantages of Gastric Sleeve Surgery

Advantages & Disadvantages of Gastric Sleeve Surgery


  • Vertical Sleeve Gastrectomy: Before & After PhotosThe smaller stomach still functions normally, so you can tolerate most foods, just in small amounts
  • Can later be converted to a Roux-En-Y gastric bypass, if desired
  • Eliminates the upper portion of the stomach that produces hormones that stimulate hunger (ghrelin), so your appetite often lessens
  • Less acid secretion, so less chance of an ulcer
  • Because the intestine remains intact, less chance of intestinal obstruction (blockage), anemia, osteoporosis, and protein and vitamin deficiency
  • No adjustments or foreign bodies (like with adjustable gastric bands) that may cause obstruction, slippage or erosion


  • Not reversible, because part of the stomach is removed
  • Weight loss may be more difficult or lessened without the intestinal bypass
  • The body still tolerates carb-rich and high-fat foods, which can slow weight loss
  • No dumping syndrome (discomfort from eating foods rich in carbs)
  • Because stomach stapling is involved, a potential for leaks and other complications exists
  • May not yet be covered by insurance companies as it’s still considered an investigational procedure
