Gastric bypass procedures (or GBP) are a group of similar operations that first divides the stomach into a small upper pouch, leaving behind a much larger lower “remnant” pouch, which then rearranges the small intestine to connect to both. Surgeons have developed several different ways to reconnect the intestines, thus leading to several different GBP names. Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.
A surgical bypass operation is performed to restrict food intake and reduce absorption of calories and nutrients for the treatment of severe obesity; this typically involves reducing the size of the stomach and reconnecting the smaller stomach to bypass the first portion of the small intestine.
A surgical procedure used for treatment of morbid obesity, consisting of the severance of the upper stomach, anastomosis of the small upper pouch of the stomach to the jejunum, and closure of the distal part of the stomach.

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), gastric bypass surgery costs between $20,000 to $25,000 on average. (more on price, below)
As with any surgery, complications are to be expected, and each complication varies in severity. Listed below are some of the complications that may arise after bariatric surgery; further along on this page, we will detail the nature of each complication.
The national mortality rate for gastric bypass surgery is 1 in 500 patients, the same as the mortality rate for any major surgery on an obese patient. The death rate varies tremendously between surgeons and programs, so you must ask each surgeon this question directly. Know that “surgical mortality” is officially defined as any death, for any reason, within 30 days of an operation.
The Gastric Bypass Alternative is an attempt to provide the world’s first replacement for weight loss surgeries, such as: gastric banding (LAP-BAND®), sleeve gastrectomy, or gastric bypass. Some professionals view bariatric surgeries as “primitive” and far from successful in the long run. However, since no true alternative was offered until now, morbidly obese people could only resort to surgical options for extreme weight loss results of over 100 pounds (or 45 kilograms).
