Gastric bypass is being favored by very many people around the world. Weight-loss surgery changes the anatomy of your digestive system to limit the amount of food you eat and digest. The surgery aids in weight loss and lowers your risk of medical problems associated with obesity.
Gastric bypass is preferred by surgeons because it is safer and has fewer complications than other available weight-loss surgeries. It can provide long-term, consistent weight loss if accompanied with ongoing behavioral changes.
Gastric bypass surgery isn’t for everyone with obesity, however it’s a major procedure that poses significant risks and side effects and requires permanent changes in your lifestyle. Before deciding to go forward with the surgery, it’s important to understand what’s involved and what lifestyle you must take.

The progression begins with liquids only, proceeds to pureed and soft foods, and finally to regular foods. With your stomach pouch reduced to the size of a walnut, you'll need to eat very small meals during the day. Then you'll follow a specific progression of your diet for about 12 weeks. The amount you can eat gradually increases with time, but you won't be able to return to your old eating habits.
