The second major risk arises from imbalanced fluid or electrolyte levels, particularly hyponatremia (sodium deficiency, overhydration, or water intoxication). This translates to a few published marathon deaths worldwide in a typical year, although the authors lamented the lack of a central registry for the information. In 2016, a systematic medical review found that the risk of sudden cardiac death during or immediately after a marathon was between 0.6 and 1.9 deaths per 100,000 participants, varying across the specific studies and the methods used, and not controlling for age or gender. The age distribution ranges widely, from the teens through the sixties.
