Sleeve Gastrectomy

Laparoscopic Sleeve Gastrectomy

Laparosopic sleeve gastrectomy is a bariatric procedure that offers some patients a great alternative to gastric bypass or adjustable gastric banding. Sleeve gastrectomy is particularly effective as a primary procedure for those with Body Mass Index (BMI) of 35 – 45, and as a staged procedure for  patients with very high BMI, greater than 70. 

This procedure works mainly by reducing stomach volume, dividing it vertically, and removing approximately 80 percent of the stomach, leaving a long vertical "sleeve" that is shaped like a banana.There is no intestinal bypass with this procedure. The portion of the stomach that is removed produces ghrelin, a hormone that stimulates appetite. This procedure reduces, but does not eliminate, a person's appetite. Patients can expect to lose 50 to 70 percent of excess weight over a one to two year period after this procedure. 

  •  Allows normal absorption of most medications, unlike gastric bypass.
  • Eliminates of the portion of the stomach that produces a hormone that stimulates hunger
  • Minimizies the chance of ulcers 
  • A reduced chance of intestinal blockage, anemia, osteoporosis, protein deficiency and vitamin deficiency
  • Promising option for people with anemia, Crohn's disease or other high risk factors


  • The potential for inadequate weight loss or weight regain 
  • Higher BMI patients may require a second-stage procedure later to help lose additional excess weight
  • Soft foods that are high in calories – such as ice cream, milk shakes, etc. – can be absorbed and may slow weight loss
  • Possible leaks or complications may arise since this procedure does involve stomach stapling 
  • Not reversible
  • Considered investigational by most insurance companies
