Central diabetes insipidus (CDI) is a rare endocrine disorder that can pose significant risks in the perioperative setting, especially when routine fasting and fluid restriction are applied. We report the case of a 34-year-old man with a history of CDI who underwent surgical drainage of a perianal abscess and subsequently developed severe hypernatremia and neurological symptoms due to postoperative water restriction. Prompt fluid resuscitation and endocrinology consultation led to rapid recovery. This case underscores the importance of early recognition and individualized perioperative management, including desmopressin replacement and tailored fluid strategies in CDI patients undergoing surgery.
