Dr. Chicharro explains that there is no clear reason why many runners need to go to the bathroom while running. In the studies that have been done, there is also no single cause to explain the disorder.

Increased intra-abdominal pressure, reduced blood supply to visceral areas due to redistribution of blood to running-related muscles, and gut hormones that stimulate excretion may be at the root of this problem, causing many runners to not perform at their best when running.

Another possible explanation is that many runners are stressed and unable to control their nerves and psychology, leading to difficulty sleeping before the race. This can lead to disturbances and cause intestinal discomfort, when they compete.

Dr Chicharro stresses that nutrition can also play a role, and can also be a clue to what to do about it. "We have to remember that certain foods can also contribute to the need to go to the bathroom while running. These are foods that are high in fiber and gas-producing, such as fruits, salads or cereals," he says.

He then offers some practical advice for runners who frequently have to interrupt their runs to go to the bathroom. “I recommend avoiding foods high in fat and also monitoring your caffeine intake,” says Chicharro. “There are certain energy gels, energy bars, electrolyte drinks that contribute to the urge to go to the bathroom. Finally, it is important to eat at least two hours before you start running. Only by following this rule can the problem be solved.”

A study by the International Society of Sports Nutrition found that going to the bathroom before a competition is closely related to competition performance. Accordingly, this helps runners increase their maximum exercise time threshold from 27 to nearly 32 minutes.

Another study by the association, conducted with 15 triathletes, found that defecating before a race improved performance by 17%. "Defecation increased blood flow to the prefrontal region of the brain and improved oxygenation in the lower abdomen. This improved brain function and runners' performance," the study said.
