Clinical condition

A 24-year-old female competitive runner presents to the medical tent at the finish line of a marathon feeling confused and nauseated, with a throbbing headache that began near mile 20. She reports drinking water at every aid station throughout the race and estimates she consumed significantly more fluid than usual due to the heat. She denies chest pain but notes her legs feel unusually weak and she vomited once after crossing the finish line.
