Abstract

Hyponatremia is generally considered to
have a plasma sodium concentration less than 135 mEq / L.It is the most common
electrolyte abnormality which is important in clinical practice. It can be caused by many etiological
factors. İnappropriate antidiuretic hormone syndrome (SIADH) is the one of the causes of
normovolemic hyponatremia. On the other hand SIADH is responsible for 30% of
hyponatremias due to cancer. It appears as a paraneoplastic syndrome especially
and most offen in the lung carcinoma. The World Health Organization (WHO)
reported that lung cancer is 12.9% of all cancers. It may manifest itself with
specific symptoms, but may also show only the paraneplastic syndrome. Therefore,
it should be kept in mind that the cause of hyponatremia must be determined and
may be a symptom of SIADH and lung cancer.
