| | SSE #88: Hyponatremia in Athletes |
 | | Although larger athletes are not immune to hyponatremia, small, slow athletes who sweat a lot, excrete a salty sweat, and are overzealous in their drinking habits are theoretically at greater risk. | | | That hyponatremia can prove fatal to otherwise healthy athletes is reason enough for sports health professionals to be aware of what the risk factors are and how the disorder can be prevented. | | | Although there is some evidence that individuals with CF are susceptible to hyponatremia (Montain et al., 2001; Smith et al., 1995), additional research is needed to determine just how prevalent the CF gene is among those who develop hyponatremia. |

| | Rhabdomyolysis is an occasional consequence of hyponatremia and should be considered in patients with muscle pain or tenderness. | | | Imaging studies may be indicated depending upon the underlying etiology of the hyponatremia (eg, chest radiograph in a patient with CHF). | | | Patients with acutely developing hyponatremia are symptomatic at a level of 120 mEq/L. Those patients with chronic hyponatremia tolerate much lower levels. |

| | To determine whether hyponatremia is a potential problem in children treated with oxcarbazepine, researchers measured serum electrolyte balances in 75 children with epilepsy before and after taking the drug and after replacing carbamazepine therapy with oxcarbazepine. | | | The dosage of oxcarbazepine taken did not influence the incidence of hyponatremia, nor did serum levels of the active metabolite of this drug, anti-epileptic comediation, age or gender. | | | News - Hyponatremia Possible Consequence Oxcarbazepine Therapy In Children |

| | Therefore, being aware of the risk factors that lead to hyponatremia is very important; recognizing and treating the condition appropriately is also very important. | | | Because the human body protects itself from hyponatremia through an intact thirst mechanism, conditions associated with alteration in thirst mechanism are more prone to induce hyponatremia. | | | This change prevents the development of hyponatremia and makes cells susceptible to dehydration during treatment, especially if significant osmolar change in the extracellular environment exists. |

| | Hyponatremia is a dangerous condition that occurs when an athlete consumes too much fluid (either water or other fluids), diluting the body's sodium levels. | | | The incidence of symptomatic hyponatremia during endurance exercise events such as the marathon and triathlon is generally low (probably less than one in 1,000 finishers). | | | The panel also concluded that especially during hot-weather training, dehydration occurs more frequently and has severe consequences, increasing the risk of heat exhaustion and heat stroke during and immediately after activity. |
