Answer:
People develop bulimia nervosa because controlling how much or little they eat and whether or not they retain the food they eat helps them 'feel better.' It is horribly destructive, the longer it goes on the better a person has of not starving to death, but bleeding to death. Every time a person's body practices reverse peristalsis the hydrochloric acid in the stomach washes up through the throat and the mouth. If you know anything about hydrochloric acid you know that it is highly corrosive ( there are certain other chemicals in the stomach that counter balance the hydrochloric acid which is actually needed to keep the stomach from digesting itself) and it wears away at the lining in the persons throat until it eventually tears and after so many times it will begin eternal bleeding to the point of bleeding to death eternally.
