How it works
Using laparoscopy, most of the stomach — roughly three quarters — is removed. The remaining stomach holds less, so you feel full with smaller portions. Some hunger-related hormones also change.
The procedure is permanent: the part of the stomach that's removed cannot be restored.
Who may qualify?
General criteria are the same as for bariatric surgery (see who may qualify). The sleeve may not be the best choice in some situations — for example, if you have significant reflux — in which case other alternatives are discussed.
Before surgery
Preparation includes a complete medical evaluation, tests, nutrition guidance and, when appropriate, a psychological assessment. You'll also receive specific instructions for the days before surgery.
Recovery and diet
After surgery, your diet progresses in stages: liquids, purées, soft foods and finally solid foods in small portions. Your hospital stay and return to activities depend on how you progress.
You'll need vitamin and mineral supplements and long-term follow-up visits.
Results and risks
Weight loss and improvement in related conditions vary from person to person and depend largely on changes in eating, physical activity and follow-up. No one can guarantee a specific result.
Possible risks include bleeding, staple-line leak, blood clots, reflux, narrowing and nutritional deficiencies. We go over them in detail during your consultation.
