The chi-square test was used to examine the relationship between hyponatremia and outcome. The data were analyzed with SPSS version-21.0. Results: Males made up 61.8% of the sample, while females made up the remaining 38.2%. The average length of hospitalization was five days (±3 SD). Hyponatremia was present among 59 (28.5%) of the inpatients (43 males and 16 females), out of which a majority (45) recovered and 11 died while the chronic liver disease and diabetes mellitus were common comorbid observed in relation to hyponatremia among elderly population.
