The medical burden can be severe even when the patient does not appear emaciated. Use DSM-5 criteria to identify the syndrome, but do not let diagnostic refinement delay acuity assessment. Anorexia nervosa involves restriction with low energy availability and weight or shape disturbance; bulimia nervosa combines recurrent binge eating with compensatory behaviour; binge-eating disorder involves recurrent binges without regular compensation; and ARFID causes restrictive intake without weight- or shape-driven body-image disturbance. The immediate clinical question is whether the patient can be treated safely in the current setting. Bradycardia, hypotension, hypothermia, electrolyte depletion, rapid weight loss, and mental-status change shift the priority to medical stabilization.
