First-Line Outpatient Treatment of Anorexia Nervosa
Guidelines consistently identify outpatient care as the first-line treatment setting for anorexia nervosa. Management integrates structured nutritional rehabilitation with evidence-based psychological intervention, targeting measurable weekly weight restoration.
Treatment Setting
Outpatient management is the recommended starting point. The treatment plan addresses both the nutritional and psychological dimensions of the condition, with specific clinical targets established for this setting.
Treatment Approach
Management combines nutritional rehabilitation — including structured refeeding and selected supplements where indicated — with one of several recognised psychological therapies. The choice of psychological approach takes patient age and clinical context into account. Medication may be considered as an adjunct in specific circumstances, but is not used as the primary or sole intervention.
Full regimen details, therapy sequencing, and monitoring parameters are in the structured protocol below.
Clinical Target
In the outpatient setting, the treatment goal is a weekly weight gain of 0.2–0.5 kg.

- All guidelines which provided information on the treatment setting (n = 7) consistently recommended outpatient treatment as a first-line therapy setting for patients with AN.
- Although the extent to which information on artificial feeding was given differed among guidelines (e.g., concerning refeeding practice, duration, or indication), guidelines consistently favored oral enteral nutrition over parenteral nutrition which should only be used as a last option.
- All seven guidelines recommended family-based therapy, particularly for younger patients.
- For individual psychotherapy, most guidelines recommended cognitive-behavioral therapy (n = 6) which intervenes at the symptom level and centers on the modification of dysfunctional behaviors and cognitions that maintain the disorder.
- Two guidelines made the general recommendation that medication should not be used as the sole or primary treatment for patients with AN (Spain, the United Kingdom) or that there is no specific medication to treat AN (France).
- Weight gain per week in inpatient and outpatient settings, mostly ranging between 0.5–1.5 and 0.2–0.5 kg, respectively.
