Due to the provision of fluids, the use of specific drugs, and the body's reaction to pain and stress, SIADH is more prevalent among patients who are recovering from surgery in a hospital. Additionally, small-cell lung cancer, in particular, is frequently discovered in those who have the disease. Malignancy, lung illnesses, CNS problems, and drugs are the most frequent risk factors for the syndrome of inappropriate antidiuretic hormone.

Considering that the patient has consumed 40 packs of tobacco per year, this greatly increases her risk of developing SIADH. Increased age: Age is a significant independent risk factor for hyponatremia, making elderly individuals a high-risk population for its development. The patient in this case is already 77 years old.
