How do i help my girlfriend with an eating disorder? please i need some advice.

Kindness: You're kind to want to help her with her eating disorder. If she has not had a professional evaluation and diagnosis, that's a good place to start. A professional can determine whether she meets criteria for an eating disorder. Her doctor will then work with her to develop a treatment plan to eliminate the problem. If you can play a role in her treatment plan she can let you know. Ask her.

Self image: Eating disorders are usually associated with a distorted self image. You can help by letting your gf know your perception of her body image and by helping her get the professional help she needs.
