In anorexia nervosa, it is necessary to establish a therapeutic alliance between doctor and patient. Patient usually feels no motivation to improve. The different treatments options to combine, in terms of the patient status, are: nutritional rehabilitation, cognitive-behavioral, family and interpersonal psychotherapies and pharmacological treatment. It can be carried out at the ambulatory, at the day-hospital or by medical stay, even beyond patient will.

Nowadays, the nutritional rehabilitation is the best treatment established and it is the core treatment. About the psychotherapies, the cognitive-behavioral is the most used because it has exposed better results in all different studies proved and in clinical practices, followed by the family therapy which is the responsible of the patient family's treatment.
