Loss of appetite, Help, Please!?

That's pretty weird. Are you sure you don't think you are fat? I am anorexic and I am being forced to recover (against my will). You are at a healthy weight, you aren't too thin, but you aren't even close to being fat. You should be happy with your body right now. I suggest talking to your mom what's going on, just make sure you say you do not think you are fat! You might have something caused celiac disease. I have it. Celiac disease can cause you to have a loss of appetite, weight loss, diaheria, constipation or a bloated belly. Celiac disease is easily treated by being put on a gluten free diet for the rest of your life. If you have any of the symtoms I have mentioned I would go to the doctor and get a blood test done for celiac.
