Women have a higher risk of hospital admission associated with hyponatremia than men while using diuretics.

Background: Hyponatremia is a common electrolyte disturbance and known adverse drug reaction of diuretics. Women tend to be more susceptible for diuretic associated hyponatremia. The aim of this study was to find more evidence whether women have a higher risk of diuretic associated hyponatremia than men measured at hospital admission for specific diuretic groups and whether there is a sex difference in risk of severity of hyponatremia.
