Eating disorders are mental illness that usually young girls have. The main kinds of eating disorders are anorexia nervosa & bulimia nervosa...both of them are also dangerous & can cause different problems including death. Those aren't the only ones though. There is also one called compulsive eating which means that the person can't stop eating & feels very depressed about it. I will mostly be talking about anorexia & bulimia though becoz I know more about those two.
