You and your running partner are running your first marathon together. You have both done all the ...

It is likely that my running partner is suffering from hyponatremia, a condition in which blood sodium levels are dangerously low (clinically defined as a blood sodium concentration less than 136 milliequivalent per litre of blood). Individuals who sweat heavily or consume little or no sodium in their diets are at increased risk of suffering from hyponatremia. Her symptoms of a headache, dizziness, fatigue, nausea, and muscle cramps match those of hyponatremia. Hyponatremia can occur in active people who drink large volumes of water and fail to replace sodium. Severe diarrhea, vomiting, or excessive prolonged sweating can also cause hyponatremia. If hyponatremia is left untreated, it can lead to seizures, coma, and death. Treatment for hyponatremia includes replacement of the lost minerals by consuming liquids and foods high in sodium and other minerals. It may be necessary to administer electrolyte-rich solutions intravenously if the person has lost consciousness or is not able to consume beverages and food by mouth.
