Ileojejunal bypass

The ileojejunal bypass is an experimental surgery designed as a remedy for morbid obesity.

It was first performed on a series of patients at White Memorial Hospital, Los Angeles, California, in the mid- to late-1970s. Patients admitted to the program had to meet all of the following requirements:

1. They must have been diagnosed as "morbidly obese"'
2. They must have had a lifelong history of conventional forms of dieting, all of which failed, and
3. They must have passed a series of psychological tests to show that both:
4. there was no psychosomatic basis for their condition, and
5. they were mentally stable enough to accept the consequences of a life-changing surgery.
