Clinical Setting

Bulimia nervosa (ICD-11 6B81) is managed primarily in an outpatient setting. International guidelines consistently place structured outpatient therapy at the centre of initial management, with the choice of modality guided by patient suitability and local availability.

Treatment Approach — Partial Overview

First-line treatment centres on structured outpatient psychotherapy. Cognitive-behavioral therapy is prominently recognised across multiple guidelines as a key first-line modality, though the full protocol encompasses additional evidence-based psychotherapeutic options and the role of nutritional counseling within the overall plan. The complete framework — including the preferred formats, sequencing, and adjunct interventions — is available in the full protocol.

Among the guidelines reporting on the prioritized treatment setting of BN, all recommended outpatient therapy as a first-line treatment (n = 5).
In agreement, five guidelines recommended cognitive-behavioral therapy as a first-line psychotherapy for patients with BN, particularly in an individual format.
The remaining two guidelines also made recommendations in favor of cognitive-behavioral interventions, but prioritized cognitive-behavioral, guided self-help treatment as a first-line treatment (the United Kingdom), or did not provide an explicit treatment hierarchy (Spain).
Overall, among the six guidelines which recommended self-help approaches, four highlighted the use of guided self-help based on cognitive-behavioral interventions (Australia and New Zealand, Germany, The Netherlands, the United Kingdom), that is, using structured self-help manuals supplemented with brief supportive sessions.
Interpersonal psychotherapy was recommended as an alternative to cognitive-behavioral therapy by most guidelines (n = 4), while psychodynamic therapy (n = 2) was rarely recommended.
Other than the WFSBP guideline, all available guidelines issued recommendations on specific psychological interventions.
