— If you're concerned that your child may have an eating disorder, having the conversation can be difficult.
The University of Michigan Health System suggests:

Explain to your child in a caring, loving way about your concerns.
Listen carefully to your child's response. Be aware that teens with eating disorders may be ashamed, afraid or out of control.
Explain to your child that you want to help. You may need to bring up the conversation more than once if your child denies the behavior or gets angry.
Monitor your child's Internet use, as there are sites that promote eating disorders.
Seek professional help if you think your child needs it.
