Portal hypertension in prolonged anorexia nervosa with laxative abuse: a case report with liver and kidney biopsy data.

Purpose: We previously reported three cases of portal hypertension in patients with prolonged anorexia nervosa (AN) with laxative abuse and self-induced vomiting; we now report a fourth, similar case.

Methods: A 34-year-old woman with anorexia nervosa, binge-eating/purging type (AN-BP), presented to the Kohnodai Hospital National Center for Global Health and Medicine Psychosomatic Medicine Department for treatment of low body weight. We conducted hepatic and renal biopsies and cardiac magnetic resonance imaging (CMR) to evaluate her complicated liver disease, renal failure, and cardiac insufficiency, respectively.
