Co-morbid condition resolution 12 to 24 months after sleeve gastrectomy has been reported in 345 patients. Sleeve gastrectomy patients experienced resolution rates for type 2 diabetes, high blood pressure, high cholesterol, and obstructive sleep apnea that were similar to resolution rates for other restrictive procedures such as gastric banding.

Sleeve gastrectomy is a restrictive bariatric surgery. During this procedure, the surgeon creates a small, sleeve-shaped stomach. It is larger than the stomach pouch created during Roux-en-Y bypass—and is about the size of a banana.

Sleeve gastrectomy is often performed as the first procedure in a two-part treatment. The second part of the treatment can be gastric bypass.
