Weight Restoration and Symptom Remission for Longstanding, Untreated Anorexia Nervosa in a Remote Eating Disorder Treatment Program: A Case Study

For severe cases of anorexia nervosa (AN), including when poor prognostic factors like low body mass index (BMI) and longer illness duration are present, intermediate levels of care are often indicated. Current guidelines call for treatment programs to use an evidence-based practice approach to individualize treatment and optimize outcomes. Research supports the effectiveness of intermediate levels of care, including remote programs which increase access to treatment. However, conflicting evidence exists regarding the ability to safely weight restore clients during remote care, necessitating further research. This case report highlights the viability of treating clients with AN remotely using an evidence-based practice approach, resulting in weight restoration and symptom remission. The client presented with a longstanding history of severe binge-eating/purging AN with numerous medical complications but was motivated and treatment-compliant. Her eating disorder (ED) was conceptualized using a biopsychosocial perspective and treated using a multidisciplinary, evidence-based practice approach encompassing individual, group, and supportive interventions. She was successfully discharged from treatment after 150 days, having restored weight to a healthy range and showing substantial improvements in ED, depressive, and anxiety symptoms based on validated measures. This case contributes to the evidence that remote care can be an accessible and effective treatment option, even in cases of severe AN. The case highlights how an evidence-based practice approach can enable safe weight restoration via a personalized treatment plan that emphasizes the use of remote devices and self-monitoring.
