“What is the treatment for anorexia?”

Counselling is definitely a must in the treatment of anorexia nervosa as this usually stems from the issue of feeling that the person is not in control of a lot of aspects in her life, so the only control they could have is their control of what happens to their body and their eating- which in a lot of ways becomes contradicting to the initial goal of gaining some sense of control as it gets to a point of being out of control again and the disorder takes over the person. Medications definitely will help as eating disorders rarely stand alone. There is usually a comorbid underlying depression, anxiety, or at times even psychosis. So, depending on the whole symptom profile, your psychiatrist will decide whether medication is needed right away or could wait in the course of the treatment.
I hope that helps.

She should see a psychiatrist.

She doesn’t have to take medication if she doesn’t want to. Counseling is fine but just in case it involves something more to it, a professional therapist or psychologist can figure that out

Hello,

Management will depend upon the other symptoms and causes of her anorexia. Start with a thorough medical examination followed by behavioral health treatment, such as cognitive behavioral therapy to help her manage her symptoms. Medication will depend upon her response to behavioral intervention.
