According to various studies, the prevalence of hyponatremia range from 27% to 58% in congestive heart failure, up to 49% in cirrhosis, and 28% in pulmonary infections (1).

Hyponatremia is associated with cognitive deficits, gait disturbances, falls, bone fractures (3), mortality (4), and has a significant clinical and economic burden (5).
