- Hyponatremia is a state of water excess.
- Reduced urine output from persistent antidiuretic hormone (ADH) secretion and/or low osmole intake accounts for a vast majority of cases of hyponatremia. Seldom does hyponatremia develop without impairment in water excretion when high water ingestion exceeds the normal renal water excretory capacity.
- Analysis of serum osmolality, urine osmolality, and urine Na+ along with assessment of extracellular volume status helps elucidate the cause of hyponatremia.
- The severity of symptoms and the severity of hyponatremia determine the therapeutic choice in hyponatremia.
- The rapid correction of hyponatremia must be avoided to minimize the risk of osmotic demyelination syndrome.
