Abstract : Hyponatremia, defined as a serum sodium concentration ([Na+]) <135 mEq/L. It is not a disease but rather a pathophysiologic process indicating disturbed water homeostasis. Hyponatremia should be further classified to provide directions for diagnosis and treatment. It is a heterogeneous disorder. The classifications of hyponatremia are commonly based on tonicity and volume status. The initial differentiation in hypotonic and non-hypotonic hyponatremia is important because management is different. Several studies have been conducted previously to measure the incidence of hyponatremia in medically ill patients. Several studies have demonstrated an increased prevalence of hyponatremia in the presence of co-morbid conditions. We conducted this study to bring out various causes of hyponatremia; their relation with sex, age and outcome and hyponatremia's classification and incidence in our hospitalised population.
