"Bulimia" means to "eat like an ox". A girl who is suffering from bulimia nervosa has frequent periods of "eating binges" which she feels are outside her control. Most of us indulge in a "pig-out" every now and the, but bulimics, unlike us, won´t return to normal eating patterns afterwards. They may binge-eat every day. The binges amy last 2 hours. Afterwards, the girl may feel guilty about the amount of food she´s eaten and try and get it out of her body - usually in unhealthy ways, such as vomiting and starvation.
