Abstract
Eating disorders are a spectrum of infrequent psychiatric diseases, with a prevalence that is difficult to establish in the pediatric population. They may have various systemic manifestations. We present a case of a teenager female who was referred from ambulatory endocrinology consult to the emergency department because of polydipsia and polyuria. During hospitalization, central and nephrogenic diabetes insipidus, diabetes mellitus, inappropriate antidiuretic hormone secretion syndrome and cerebral salt wasting syndrome were ruled out. Once the organic causes were excluded, an eating disorder with psychogenic polydipsia was identified.
