What is the most common causes of hyponatremia in cancer patients?
The syndrome of inappropriate anti-diuretic hormone (SIADH) is the most common cause of hyponatremia in cancer patients, with higher rates among patients with small-cell lung cancer and head and neck cancers compared to others.
What are the other causes?
The other potential causes of SAIDH are the release of the anti-diuretic hormone, which is not mediated by an osmotic or volume stimulus, and includes pain, nausea, and medications (cisplatin, cyclophosphamide, vinblastine, and vincristine).
