Runner's Diarrhea: Expert Reveals Causes and Prevention Tips

Runner's Diarrhea: Why It Happens and How to Prevent It Millions of runners worldwide experience the unpleasant surprise of runner's diarrhea. This condition, characterized by sudden bowel urges during or after a run, can significantly impact performance and enjoyment. Dr. Kunal Sood, a board-certified physician, sheds light on the science behind this common problem. According to Dr. Sood, the culprit is the body's sympathetic nervous system. During a run, blood flow is diverted from the intestines to the muscles, leaving the intestines more vulnerable to toxins and causing diarrhea. "The reduced blood flow to your intestines can make them more susceptible to toxins, leading to unpleasant consequences," explains Dr. Sood in his video. Dr. Sood offers practical tips to reduce the risk of runner's diarrhea. He suggests avoiding high-fiber and fatty foods before a run, staying hydrated, and avoiding running within two to three hours after a large meal. These simple strategies can help runners avoid interruptions and enjoy their runs to the fullest. Dr. Sood's expertise and clear explanations make this information valuable to both casual and serious runners alike.
