A rare pregnancy complication known as gestational diabetes insipidus (GDI) is thought to be caused by the increased production of vasopressinase by the placenta. The second or third trimester is typically when it occurs. In the context of newly diagnosed superimposed preeclampsia, this case of GDI is described in this report [1]. A 39-year-old Hispanic woman met the criteria for superimposed preeclampsia when she presented ten days postpartum with a persistent headache and elevated blood pressures in the context of a history of chronic hypertension (gravida 2 para 2). Rehash lab work was prominent for gentle height of liver capability compounds [2]. Her headache persisted despite a normalization of her blood pressure, and further examination revealed polyuria, which was thought to be vasopressinase-induced diabetes insipidus. When the patient's symptoms and polyuria improved, oral desmopressin was started [3].
