Answer

Previously, mild hyponatremia was considered relatively asymptomatic. However, evidence suggests that even mild hyponatremia can cause significant impairment, such as unsteady gait, and lead to frequent falls. This effect may be greater in elderly persons, who are more sensitive to changes in serum Na+. [18] Hyponatremia may also be a risk factor for osteoporosis and bone fracture. [19]
