Exercise-associated hyponatremia
Guidelines
Key sources
The following summarized guidelines for the evaluation and management of exercise-associated hyponatremia are prepared by our editorial team based on guidelines from the Wilderness Medical Society (WMS 2020).
1
Diagnostic investigations
Assessment: as per WMS 2020 guidelines, obtain point-of-care testing in at-risk symptomatic patients when available. Integrate all available clinical and historical information into an assessment of the patient's hydration status (history of fluid intake, food intake, presenting signs and symptoms, body weight if available, and urine output), if testing is unavailable.
B
Medical management
Inpatient care
Transfer of care: as per WMS 2020 guidelines, inform receiving caregivers about the potential diagnosis of exercise-associated hyponatremia and appropriate fluid management (withhold hypotonic fluids) when transferring care.

Nonpharmacologic interventions
Oral fluid restriction: as per WMS 2020 guidelines, advise restricting oral fluids if exercise-associated hyponatremia from fluid overload is associated with mild symptoms. Do not administer hypotonic fluids in patients with suspected exercise-associated hyponatremia.

Preventative measures
Proper hydration: as per WMS 2020 guidelines, advise avoiding sustained overhydration during exercise, as it is the primary risk factor for development of all variants of exercise-associated hyponatremia.
