Temporary Syndrome Found in Ironman Athletes reports on an amusingly named syndrome that affects endurance athletes who alternate between dehydration and overhydration:
Triathletes have to be the fittest of the fit, but a small, unpublished study of athletes who competed in an Ironman triathlon suggests that the arduous, all-terrain event can take its toll, creating a “constellation of symptoms” defined as post extreme endurance syndrome (PEES).More than a third of the athletes who sought medical attention suffered from the condition, which is characterized by decreased body temperature, nausea, vomiting, diarrhea, dizziness, headache, cramping and the inability to drink fluids, said Dr. Hilary Ann Petersen of the University of Arkansas Medical Center.
