Exercise-associated diarrhea afflicts an estimated 30% to 50% of athletes, particularly those who exercise at a high intensity in running-type sports. Athletes with a history of gastrointestinal problems (including irritable bowel syndrome, celiac disease, and lactose intolerance) are predisposed to this problem. While solutions to exercise-associated diarrhea are personal to each athlete, this feature offers guidelines that might provide some relief.
