Cirrhosis causes hyponatremia due to impaired systemic perfusion, as a manifestation of hepatorenal physiology. this is an indication of advanced cirrhosis. cirrhosis rarely causes severe hyponatremia. similar to heart failure, there is usually a fairly stable sodium of ~120 135 mm. There are two possible approaches to the diagnosis of hyponatremia: the classical method and the "lazy man's method". both are offered here. in their most basic form, the approaches require essentially the same tests (serum osmolality, urine osmolality and urinary sodium). in the classical method, one is expected to examine the patient and come to a conclusion regarding their fluid status. the. The management of hyponatremia in patients with hypervolemia can be difficult. water restriction to less than 1.25 l d is essential. sodium restriction to 70 mmol d (with the aid of a dietitian) will help with edema. a loop diuretic should be used to promote sodium and water excretion by the kidneys.

Hyponatremia is defined as a serum sodium concentration of less than 135 meq l but can vary to some extent depending upon the set values of varied laboratories.[1] hyponatremia is a common electrolyte abnormality caused by an excess of total body water in comparison to that of the total body sodium content. edelman approved of the fact that serum sodium concentration does not depend on total. Hyponatremia is an important and common clinical problem. the etiology is multifactorial. hyponatremia may be euvolemic, hypovolemic or hypervolemic. proper interpretation of the various laboratory tests helps to differentiate the various types of hyponatremia. treatment varies with the nature of onset acute or chronic, severity and symptoms.
