Hyponatremia is more common in the elderly. A number of studies suggest that even mild chronic hyponatremia is a serious danger, increasing the risks of developing geriatric syndromes, falls, low bone density, fractures, cognitive impairment, and death of all causes. Although the mechanism for the development of such complications is currently not completely clear. Questions remain about the need and methods for correcting this condition, although there is some evidence that the correction of hyponatremia improves cognitive functions, postural balance, minimizing the risk of falls and fractures. These issues are addressed in this review of the literature.
