What are the advantages of gastric sleeve plus gastric bypass surgery?

Gastric sleeve surgery allows for creation of a restrictive operation without the implantation of a foreign object. Additionally, it is not associated with dumping syndrome and requires less vitamin and mineral supplementation.

The staged approach for bariatric surgery for patients that are at higher surgical risk has tremendously decreased the risk of weight loss surgery for these patients, even when the risk of the two surgeries is added. Most patients can expect to lose 30% to 50% of their excess body weight over a 6-12 month period with the sleeve gastrectomy alone. The timing of the second procedure will vary according to the degree of weight loss, typically 6-18 months.
