Sleeve gastrectomy surgery should not be considered until you and your doctor have evaluated all other options

The proper approach to sleeve gastrectomy surgery requires careful consideration and discussion of the following with your doctor:

  • Weight loss surgery is not cosmetic surgery. The procedures do not involve the removal of fatty tissue by cutting or suction.
  • A decision to elect surgical treatment requires an assessment of the benefits and risks to the patient and the meticulous performance of the appropriate surgical procedure.
  • The success of weight loss surgery is dependent on long-term lifestyle changes in diet and exercise.
