Hi. My name is Sylvana and I am 14. One of my best friends was talking to me one night, and asked me a serious question. She asked me if loosing 10 pounds in a week and a half was serious. Of course, my first reaction was how, why, and have you been eating. She's been eating normally, but, we still don't know. She doesn't want to go see a doctor because then her parents will know, and she doesn't want that.

Does anyone know what's wrong, and have anything that we can do instead of going to the doctor? If not, how serious is this?
