Transient Diabetes Insipidus With Pituitary Dysfunction Following Abdominal Surgery: A Rare Postoperative Endocrine Complication.

Diabetes insipidus (DI) developing postoperatively is a recognized complication following neurosurgical procedures involving the hypothalamic-pituitary region. However, its occurrence after non-neurosurgical operations is exceedingly rare. We report a case of polyuria associated with hypogonadotropic hypogonadism, closely resembling central DI, following major abdominal surgery. Diagnosing DI after non-neurosurgical procedures is challenging, as polyuria is often attributed to more common causes, such as osmotic diuresis or fluid overload. Awareness of this rare but significant postoperative complication is essential for prompt diagnosis and appropriate multidisciplinary management.
