Ever wondered why running sometimes triggers an urgent need for the bathroom? Known as "runner's trots," this common issue affects many runners.
If you've ever felt an unexpected urge to find a bathroom mid-run, you're not alone.
This phenomenon, often called "runner's trots" is a common issue among runners. Research shows that up to 84% of runners experience gastrointestinal (GI) symptoms during their runs.
While inconvenient, understanding why it happens can help you take steps to prevent it.
According to Dr. Linda Nguyen, a gastroenterologist at Stanford Health Care, runner's trots occur because intense exercise activates your sympathetic nervous system (SNS).
This part of your autonomic nervous system controls automatic bodily functions like digestion, sweating, and heart rate.
When you're under stress, such as during a strenuous run, your SNS increases motility, the contractions of muscles in your GI tract, which can lead to diarrhea.
The intensity of your run can influence the severity of symptoms.
Long, intense runs, like marathons, are particularly problematic because blood flow is redirected from your gut to your muscles.
"You need blood flow in the gut to properly digest food," Dr. Nguyen explains. When that process is interrupted, GI distress often follows.
While there’s no guaranteed way to avoid GI issues on a run, there are several strategies you can try:
Eating too close to your run can increase the likelihood of needing to use the bathroom.
If possible, avoid eating for a few hours before your workout. For runs over an hour, you may need a small snack to maintain energy.
Certain foods are more likely to trigger GI distress. Dr. Nguyen advises avoiding these before a run:
Instead, opt for:
It may take some trial and error to find the best pre-run snacks for your body.
Some runners tolerate small amounts of fruit or a granola bar well, while others need to avoid these entirely.
Stress can exacerbate GI issues, especially before a big race.
Techniques like meditation, deep breathing exercises, or even a warm cup of peppermint tea can help calm your nerves and your stomach.
If you feel the urge to go during a run, there’s not much you can do but find the nearest restroom.
However, if this happens frequently, consider adjusting your diet, stress management techniques, or pre-run meal timing.
While runner's trots can be an unwelcome aspect of running, understanding why it happens and making small adjustments to your routine can significantly reduce the chances of it occurring.
By experimenting with your pre-run snacks, managing stress, and timing meals effectively, you can keep GI distress to a minimum.
So the next time you lace up your running shoes, you can focus on your pace and goals without worrying about unscheduled bathroom breaks. Happy running!
