Avoidant restrictive food intake disorder (ARFID)

Avoidant restrictive food intake disorder (ARFID) was introduced in DSM-5 and has more recently been included in ICD-11. It presents with restrictive eating patterns but the diagnosis hinges on the subsequent health problems and functional impairment, either physical or psychological, related to the restriction. Critically, the restricted eating is not associated with concerns about body image, weight or shape, in contrast to other restrictive eating disorders. This article provides an educational overview of ARFID, its presentation and subtypes, known comorbidities, and assessment and treatment options. ARFID-specific cognitive behavioural therapy and family therapy approaches have been developed but no randomised intervention studies have yet been undertaken. Case scenarios demonstrate how the diagnostic criteria may apply in clinical practice.
