anorexia nervosa
If your loved one shows most signs, but is not 15% underweight or lacking her monthly period, you should still be worried. He/she may not fit the medical description of "anorexia", but may be very close to it.
bulimia nervosa
I would like to apologize for not supplying more information about compulsive overeating. I do not have a lot of information on the subject. I hope to add information in the subject soon. Until then, I am sure you can find information in the links I have to other sites.
