A recent incident involving an elite Hyrox athlete in China has brought an uncomfortable medical subject into unusually public view: losing control of the bowels during strenuous exercise.
It may make headlines when it happens during a major athletic competition. For people who experience bowel leakage in everyday life, however, it is usually anything but amusing.
The medical term is fecal incontinence, also called accidental bowel leakage. It can range from occasional staining or leakage of liquid stool to an inability to control a bowel movement.
And while strenuous exercise can sometimes bring on symptoms, fecal incontinence is not simply an “athlete problem.”
Why Can It Happen During Intense Exercise?
Long-distance runners and other endurance athletes are familiar with the fact that vigorous exercise can affect the gastrointestinal tract.
During strenuous exercise, blood flow is redistributed toward working muscles and away from parts of the digestive system. Running also subjects the abdomen and pelvic floor to repetitive movement and mechanical stress. Add factors such as pre-race meals, caffeine, hydration, supplements, anxiety, diarrhea and the sheer duration and intensity of an event, and bowel urgency can sometimes become difficult to control.
That does not mean exercise itself is necessarily the underlying cause of fecal incontinence.
In fact, bowel leakage can have several contributing factors, and sometimes exercise simply exposes a problem that is otherwise less noticeable.
It’s More Common Than Many People Realize
Because bowel leakage can be embarrassing to discuss, its frequency is easy to underestimate.
Research involving female runners and other athletes has documented fecal incontinence in otherwise active people, including individuals who experience symptoms while exercising but not during ordinary daily activities.
More importantly, fecal incontinence occurs throughout the general population. It can affect men and women and people of many different ages.
What Can Cause Bowel Leakage?
Normal bowel control depends on several systems working together: stool consistency, the rectum’s ability to store stool, sensation within the rectum, the anal sphincter muscles, the pelvic floor and the nerves controlling them.
A problem in any of these areas can contribute to leakage. Possible causes include:
- Diarrhea
- Chronic constipation with overflow
- Disorders affecting the rectum or colon
- Injury or weakness of the anal sphincter or pelvic floor
- Nerve problems
- Previous pelvic or anorectal surgery
- Injuries related to childbirth
Conditions such as inflammatory bowel disease or irritable bowel syndrome may also contribute in some patients, particularly when they cause diarrhea or severe urgency.
That is why two people with what appears to be the same symptom may need very different treatment.
A Symptom Worth Mentioning to Your Doctor
Some people quietly adapt their lives around bowel leakage.
They learn where every restroom is located. They avoid particular foods before leaving home. They carry extra clothing. Some stop exercising, traveling or participating in social activities.
Those strategies may reduce embarrassment, but they don’t explain why the problem is occurring.
Evaluation usually begins with something much less complicated: a careful conversation about when the leakage occurs, stool consistency, urgency, medications, diet, bowel habits, previous surgeries and other medical conditions.
Depending on the circumstances, additional evaluation may include a physical examination and tests designed to assess the colon, rectum, pelvic floor, anal sphincter or the nerves and muscles involved in bowel control.
One such test is anorectal manometry, which measures aspects of rectal sensation and the function of the anal sphincter muscles.
Not every patient needs extensive testing. The appropriate evaluation depends on the individual’s symptoms and medical history.
Treatment Depends on the Cause
There is no single treatment for fecal incontinence because there is no single cause.
For some people, improving diarrhea or constipation may substantially improve bowel control. Dietary changes, fiber or medications may be appropriate in selected patients. Other patients may benefit from bowel training, pelvic-floor exercises or specialized biofeedback therapy.
More advanced treatments are available for certain patients when conservative measures are insufficient.
The important point is that bowel leakage should not automatically be accepted as an inevitable consequence of aging, childbirth or exercise.
Don’t Let Embarrassment Prevent the Conversation
The publicity surrounding bowel problems in elite athletes may have one useful consequence: it makes a normally hidden medical problem easier to talk about.
You don’t have to be an endurance athlete to experience fecal incontinence. And you don’t need to wait until symptoms become severe before mentioning them to your physician.
If bowel leakage is recurring, worsening, limiting your activities or changing the way you live your life, it deserves a medical evaluation.
Sometimes the first—and most important—step is simply being willing to talk about it.
