European Eating Disorders Review, EarlyView., 2023 Abstract Eating disorders (EDs) present a chronic issue to child paediatric mental health services due to their high mortality and relapse rates. The transition from Child and Adolescent Mental Health Services to Adult Mental Health Services is a particularly high‐risk period for young people with EDs given their high vulnerability to change, which can
