[Polyuria and polydipsia in acute fatty liver of pregnancy. Discussion based on a case].

We report the case of a 25-year-old nullipara in whom polyuria and polydipsia occurred 8 weeks before the first symptoms of acute fatty liver of pregnancy and disappeared a few days after delivery. This time course suggests that polyuria and polydipsia were closely related to acute fatty liver of pregnancy. Thus, this diagnosis should be envisaged in any woman with normal blood levels of glucose and calcium, and complaining of polyuria and polydipsia in the third trimester of pregnancy.
