There are definitely signs that signal possible trouble. Dieting or restricting food is the first one. Eating and then leaving the table to go to the bathroom may be another. Many parents never notice that a youngster goes to the bathroom and runs water to cover up the sound of vomiting. Also, look for empty wrappers hidden under the bed or in other places.
Some kids chew food and spit it out into bags that they hide in their room.
Many youngsters worry about their weight or shape, but excessive concern about this is a warning sign. Asking a parent to buy weight loss products is another. A parent needs to begin early to help a young person adjust to the fact that her body starts to change starting anywhere from age 9 to 11. This can really freak out a kid who is used to being skinny, and suddenly starts to develop hips and breasts. Also watch out for your sons and daughter's coaches.
