Certain conditions can cause decreased sodium in the blood. Specific causes of hyponatremia include:
Water poisoning (water replacement without electrolyte replacement).
Problems in the kidneys, heart or liver.
Medications: such as diuretics, Heparin, certain chemotherapeutics (Aminoglutethimide, Cyclophosphamide and Vincristine).
Conditions related to steroids, hormones or metabolic defects, such as a syndrome that alters the secretion of antidiuretic hormone (SSIHA). If this occurs, you urinate frequently and the kidneys excrete too much sodium. This can result from many conditions, including certain types of lung cancer.
