Title: Exercise Associated hyponatremia<br/>Author: Brian Corwell<br/><a href='http://umem.org/profiles/faculty/294/'>[Click to email author]</a><hr/><p>
Sodium Supplementation and Exercise-Associated Hyponatremia (EAH) during Prolonged Exercise (ultramarathon running)</p>
<p>
Weight loss of around 4% body weight (relative to pre race weight) can be anticipated to maintain euhydration in such a prolonged event</p>
<p>
Those who become symptomatic with EAH have either gained weight or lost less that 3-4% body weight</p>
<p>
<strong>Overhydration</strong> rather than inadequate supplemental sodium intake is a greater contributor to the development of EAH</p>
<p>
There is a suggested link between EAH and rhabdomyolysis. The mechanism remains unknown and it is unclear which condition may augment the other. Further research is needed.</p>
<p>
Take home: Avoid overhydration during prolonged exercise to prevent EAH.</p>
