anorexia is definately a disease. it'a anorexia nervosa- i'm reading a book on it and it's a really really bad mental illness. anorexia is when you go on an exteme low calorie diet where one will have as low as they can. and if they are forced to eat more then they think the should they throw it up(no- it's not bulemia- there's a difference. bulemia is where a person binge eats and throws it up and does that with everymeal) there are degrees that one can become obbsessed and have anorexia though...
