Symptomatic exercise-associated hyponatremia (EAH), which is relatively common among marathon runners, is an uncommon event among ultra-endurance athletes. A 44-year-old man presented to the emergency department with increased thirst after successfully completing a 100-mile mountain bike race in Leadville, Colorado. Initial laboratory tests revealed a blood sodium level of 116 mEq/L. The primary etiologic factor in EAH is fluid consumption in excess of fluid losses in prolonged exertion. Early diagnosis and management is crucial to prevent cerebral and pulmonary edema.
症状性运动相关低钠血症（EAH）在马拉松跑者中较为常见，但在超长耐力运动员中较为少见。一名 44 岁男性在成功完成科罗拉多州利德维尔的 100 英里山地自行车赛后，出现口渴增加症状并到急诊就诊。初始实验室检查显示血钠水平为 116mEq/L。EAH 的主要病因是在长时间剧烈运动中液体摄入超过液体丢失。早期诊断和治疗对于预防脑水肿和肺水肿至关重要。
