Surgeons alter the configuration of the stomach and small intestine to reduce the amount of food patients can eat and digest. For patients who meet certain criteria, gastric bypass surgery can be performed using minimally invasive (laparoscopic) techniques. This approach can reduce blood loss, trauma to muscles and other tissue, risk of infection, length of stay in the hospital, as well as pain and recovery time.
The typical hospital stay for gastric bypass is three days. Patients generally are able to return to work after a few weeks of recovery.
