Hyponatremia, a risk factor for osteoporosis and fractures in women

Summary Hyponatremia has been linked to an increased risk of osteoporosis and fractures. We found an increased hazard ratio of major osteoporotic fractures adjusted for potential confounders, including osteoporosis and medication. A reduced BMD was not sufficiently explaining the association. Our data indicate that hyponatremia should be considered a risk factor for osteoporosis and fractures.
