The Differences Between Bariatric Surgical Procedures
As one of the nation's leading bariatric surgeons, Michael Feiz, M.D., F.A.C.S. is an expert on all of the various types of procedures currently being offered. While certain procedures have become more popular in recent times, as discussion has centered largely on Lap Band vs. sleeve gastrectomy, the three basic procedures remain essentially the same.
As its name indicates, the bypass – the oldest of the most commonly performed procedures -- actually shortens the path by which food is digested. A very small mini-stomach of sorts is created which connects to the small intestine further down from where food ordinarily enters the digestive organ. The result is that the appetite is greatly reduced because eating large amounts of food becomes uncomfortable. Also, bypassing part of the intestine means that fewer calories can be absorbed. While extremely effective, this method has a number of downsides and possible side effects.
