Sleeve gastrectomy is a restrictive surgical weight loss procedure that limits the amount of food you can eat and helps you feel full sooner. In this procedure, a thin, vertical sleeve of stomach is created and the rest of the stomach is removed. The sleeve is about the size of a garden hose.


  • Surgery 1 hour
  • 1-2 day hospital stay
  • 2-4 weeks recovery period


  • Quick weight loss, patients can lose about 60-80 percent of their expected weight within 24 months after surgery
  • Does not create malabsorption (the inability to absorb certain sugars, fats, proteins or vitamins from food)


  • Suture-line leakage may occur
  • Sleeve stricture may occur
  • Sleeve gastrectomy surgery may cause bleeding
  • Nausea and heartburn may occur
  • Sleeve gastrectomy may cause vitamin B12 deficiency

Other Considerations

  • Not reversible
  • No dumping syndrome
  • Vitamins recommended (B12)
  • No medication restrictions
  • Liquid diet for one month
