I agree that most bulimics do not die. Most bulimics maintain a normal weight and are not anorexic.
But some bulimics are crossovers - ie. they also have anorexia. Karen Carpenter was one. A friend of mine who died at 23 from it was also anorexic/bulimic.
Anorexic/bulimics are more likely to die.
Not nearly as often as victims of domestic violence.
"Anorexic/bulimics are more likely to die."
Maybe. But as I said, the U.S. statistics on these cases are cooked.
