Abstract :

Hyponatremia is considered as the most common electrolyte disorder in hospitalized patients. In the present study 100 cases of hyponatremia were investigated for aetiological factors and clinical features. Syndrome of inappropriate secretion of diuretic hormone (SIADH) constituted major group with 34 (34%) cases. The other causes of hyponatremia were congestive heart failure, renal failure, Diabetes mellitus, hypothyroidism and acute gastroenteritis. Common clinical features in mild hyponatremeia were nausea (20%) vomiting (5%) headache (5%) and muscle cramps (5%). Asymptomatic cases constituted 60% of the total cases. However in severe cases of hyponatremia altered sensorium was the major clinical feature; the other clinical features observed in these cases were seizures, gait disturbance, dysarthria and coma.
