Approach to anorexia nervosa and atypical anorexia nervosa in adolescents.

Abstract

To address screening, diagnosis, and treatment of adolescents with anorexia nervosa and atypical anorexia nervosa in primary care. A literature search was conducted in PubMed using the subject headings anorexia nervosa, adolescents, COVID-19, review, guidelines, and primary care. Applicable articles were reviewed, with key recommendations summarized. Most evidence is level I. Recent studies suggest that the global COVID-19 pandemic contributed to an increase in the incidence of eating disorders, particularly among teenagers. This has resulted in increasing responsibility for primary care providers regarding the assessment, diagnosis, and management of these disorders. Moreover, primary care providers are in ideal positions to identify adolescents at risk of eating disorders. Early intervention is of utmost importance for avoiding long-term health consequences. High rates of atypical anorexia nervosa indicate a need for providers to have awareness of weight biases and stigmas. Treatment primarily involves a combination of renourishment and psychotherapy, generally through family-based therapy, with pharmacotherapy playing a lesser role. Anorexia nervosa and atypical anorexia nervosa are serious, potentially life-threatening illnesses that are best addressed through early detection and treatment. Family physicians are in an optimal position to screen for, diagnose, and treat these illnesses.
