Exercise associated hyponatremia is a major cause of collapse and confusion after prolonged exercise. Although initially it was attributed to salt loss, it is now predominantly due to excessive consumption of hypotonic fluids during and after the period of exertion and its associated diuresis suppression 1. Other individual risks include female gender, slow running, NSAID use and excessive fluid ingestion. The weather conditions and advice given to the runners also have a major role in the incidence2.

The objective of this case series is to view the presentation, treatment and response of those runners who presented with exercise-induced hyponatremia.
