Gastric bypass surgery involves two primary steps. The first step consists of reducing the size of the stomach. The second step involves rerouting the food directly into the small intestine. This results in the body absorbing fewer calories. These procedures can be performed through a large incision in the stomach or through several small incisions using a tiny camera called a laparoscope.

There are medical facilities throughout the world that offer this surgery with qualified physicians at reasonable prices. Mexico is a popular destination for gastric bypass surgery with several locations specializing in this procedure. India, Spain, Taiwan and Israel offer this surgery, and many of the physicians are board certified. There are travel agents trained to help individuals planning surgery abroad make all of the necessary arrangements and reservations.
