Sleeve Gastrectomy

A laporoscopic gastric sleeve, or sleeve gastrectomy, is a restrictive procedure that limits the amount of food you can eat by reducing the size of your stomach. During this procedure, a thin sleeve of stomach is created using a stapling device. This sleeve will typically hold between 50 to 150 mL, and is about the size of a banana. The excised portion of the stomach is removed.

An analysis of clinical structures involving sleeve gastrectomy patients reported that patients achieved an average of 55% excess weight loss. Another clinical study reported the following improvements:

  • Improvement in type 2 diabetes in 86% of patients
  • Improvement in high cholesterol in 77% of patients
  • Resolution of high blood pressure in 42% of patients
  • Resolution of obstructive sleep apnea in 30% of patients


  • Limits the amount of food that can be eaten at a meal
  • Food passes through the digestive tract in the usual order, allowing vitamins and nutrients to be fully absorbed into the body
  • No postoperative adjustments are required
  • In clinical studies, patients lost an average of 55% of their excess weight
  • Shown to help resolve high blood pressure and obstructive sleep apnea, and to help improve type 2 diabetes and hyperlipidemia
  • A thin vertical "sleeve" of stomach is created using a stapling device.


  • The following are in addition to the general risks of surgery:
  • Complications due to stomach stapling, including separation of tissue that was stapled or stitched together and leaks from staple lines
  • Gastric leakage
  • Ulcers
  • Dyspepsia
  • Esophageal dysmobility
  • Nonreversible since part of the stomach is removed

Talk with your surgeon about the possible surgical risks.
