Can a doctor tell if your bulimic by checking your throat?

Yes your doctor can most likely tell the severe cases of bulimia. Bulimia is a terrible thing to have, its a bad habit and very unhealthy, so its probably better that your doctor knows that you are bulimic. He/She can help you through and make you normal. This is even more unhealthy than being fat. Im really not trying to be mean, I just want you to realize that you are making a bigger risk for yourself for bad health. You can get yourself into diseases and problems such as acid reflux disease or even pancreatitis. Just remember, your doctor is there to help you not to scold you. Ask your doctor about what you could do to stop the life-threatening habit. I wish you well! I really hope you can get past those habits!
