Several: #1 going to the restroom(to purge) immediately after a meal. #2 erosion of the enamel of the teeth from the stomach acid. #3 finding emetic(vomiting) agents in your childs room. #4 weight loss in spite of seemingly adequate nutritional intake. #5 a childs extraordinary focus on food and "weight gain".
