A sleeve gastrectomy is performed by removing approximately 80% of the stomach. This creates a small tubular stomach (sleeve).
This procedure is different than the bypass in that it causes no mal-absorption of nutrients. Therefore, anemia, osteoporosis and vitamin deficiencies are rare.
Different than the band, there is no foreign body around your stomach. Patients can continue to take complex medications after a sleeve and not worry about the absorption of medication. The procedure is usually performed with laparoscopy and has a short recovery time.
The sleeve gastrectomy helps you lose weight because:
- The stomach pouch is very small
- The stomach area that produces Ghrelin is removed, and this decreases hunger
