Increasing age (>30 y) is a risk factor for hyponatremia in hospitalized patients. [14] Men appear to be more likely to develop mild or moderate, but not severe, hyponatremia. [14] Low body weight is also a risk factor for hyponatremia. Women appear to be more prone to drug-induced hyponatremia and to exercise-induced hyponatremia (marathon runners), although this may be an association with low body weight rather than sex. [5]
