A gastro bypass is also known as a lapband procedure. In a gastro bypass, the surgeon segments your stomach in to what is referred to as pouches. A gastro bypass creates a smaller upper pouch and then a bigger pouch. The gastro bypass then involves re-aligning your small intestine so that each of these pouches stay connected to it.
Doctors have developed multiple alternate methods to connect and reshape the intestines. Each of these methods is referred to by an alternate gastro bypass names. All gastro bypass methods lead to the same goal, which is a substantial reduction in the amount of food your stomach can hold. Each gastro bypass method also has its unique risks, side effects and long term results.
