Síndrome polidípsico-poliúrico en trastornos de la conducta alimentaria de la adolescencia

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 mani-festations. We present a case of a teenager female who was referred from ambulatory endocrinology consult to the emer-gency department because of polydipsia and polyuria. During hospitalization, central and nephrogenic diabetes insipidus, diabetes mellitus, inappropriate antidiuretic hormone secre-tion syndrome and cerebral salt wasting syndrome were ruled out. Once the organic causes were excluded, an eating disorder with psychogenic polydipsia was identified.
