Rumination Syndrome

The name Rumination Syndrome sounds kind of pleasant actually, but the details are distressing:

Rumination Syndrome, is characterized by the repeated painless regurgitation of food following a meal which is then either re-chewed, re-swallowed or discarded. It is an under-diagnosed disorder possibly due to the fact that most physicians do not recognize the symptoms of the disorder. – Wikipedia
