Changes in eGFR in adolescent and young adult inpatients receiving nutritional rehabilitation for a restrictive eating disorder: a five-year clinical audit

Impaired renal function was observed in approximately one third of this sample of adolescents and young adults hospitalised with restrictive eating disorders and typically resolves during the admission. A high protein prescription of 1.9-2.7 g/kg/day did not deleteriously affect renal function, with eGFR levels improving with nutritional rehabilitation. Prospective studies are needed to confirm the optimal protein prescription during nutritional rehabilitation in patients hospitalised with restrictive eating disorders, and to further explore outcomes in the small subgroup of patients who remain with renal impairment at discharge.
