Some athletes call it runner’s trots. Others call it diarrhea.
Whatever the name, few athletes openly discuss the topic, yet many secretly suffer. Here’s some information about this stinky topic that might help bring peace to your workouts.
Q. Does anyone else worry about undesired pit stops while exercising?
1 of 10
A. Yes. Diarrhea is a major concern for many athletes, particularly those in running sports.
Of these athletes, an estimated 20 to 50 percent suffer from "urgency to defecate." Running jostles the intestines, reduces blood flow to the intestines as the body sends more blood to the exercising muscles, stimulates changes in intestinal hormones that speed up transit time and alters absorption rate. Dehydration exacerbates the problem.
Add a pre-existing bowel problem, and you are even more likely to be bothered by pit stops as your exercise ramps up.
Q. How often do most athletes have a bowel movement?
2 of 10
A. Some athletes poop once a day. Others go twice a day, and some go once every two or three days. "Normal" is what is normal for your body.
You can learn your personal transit time by eating sesame seeds, corn or beets—foods you can see in your feces. Pay attention to how much time passes between intake and output.
Exercise (even weight-lifting) speeds up transit time, especially if you do more exercise than usual. A study with healthy, untrained 60-year-old men indicated their transit time accelerated from an average of 44 hours to 20 hours after they started lifting weights.
Q. Is my diet causing the problem?
3 of 10
A. Your diet can create the problem, but medical issues such as celiac or irritable bowel syndrome (IBS) can cause chronic loose stools.
Just being female increases the risk of experiencing loose stools, particularly at the time of the menstrual period. Add stress, pre-event jitters and high intensity effort, and it's no wonder many athletes become plagued by urgency to defecate. This can particularly affect novices whose bodies are yet unaccustomed to the stress of hard exercise.
To figure out if the problem is connected to your diet, keep a food and poop chart. For at least a week, eliminate a suspicious food. Observe any changes in bowel movements. Next, eat a hefty dose of the suspected food; observe changes. For example, if you stop having diarrhea when you cut out popcorn, but have trouble during a long run after eating a tub of the stuff, the answer becomes obvious. Eat less popcorn.
Q. What are the common dietary triggers?
4 of 10
A. Here are the main ones:
1) Fiber. Triathletes with a high fiber intake reported more GI complaints than those with less fiber. Cut back on high fiber cereals and, if needed, fruits, veggies and whole grains. Reduce your fiber intake for one to three days prior to competition.
2) Sorbitol. If you enjoy sugar-free gum, candies and breath mints that contain sorbitol (a type of sugar), take note: sorbitol triggers diarrhea in some people.
3) Coffee and tea. Hot fluids can stimulate gastric movement.
4) Fatty foods, spicy foods, alcohol and a high dose of Vitamin C.
Q. Does milk cause diarrhea?
5 of 10
A. Some athletes have trouble digesting lactose, the sugar that naturally occurs in milk. If you are lactose intolerant, you may experience gas, bloating and diarrhea. Try switching to lactose-free milk (such as LactAid Milk or soy milk).
Q. Should I go on a gluten-free diet?
6 of 10
A. Gluten, a protein found in wheat, is known to cause diarrhea in people with celiac disease. About one in 125 people has celiac (gluten intolerance).
First, get a medical diagnosis before embarking on this difficult diet. Even if diagnostic tests are negative, some people feel better avoiding gluten.
Q. I'm afraid to eat or drink anything during exercise. If I succumb, I inevitably get diarrhea. Suggestions?
7 of 10
A. I suggest you start drinking earlier and stay well-hydrated. Intestinal complaints are common in athletes who have lost more than 4 percent of their body weight in sweat. That's six pounds for a 150-pound athlete. Becoming dehydrated may have triggered the diarrhea, not the water or sports drink.
Your best bet is to train your body to tolerate fluids. Start with small amounts of water during exercise for a week or two, then transition to diluted sports drinks and then eventually to full-strength sports drinks. Or have plain water and mints or hard candies.
Q. Can I take some sort of anti-diarrhea medication?
8 of 10
A. When all else fails, consult with your doctor about taking anti-diarrhea medicine, such as Imodium, one hour pre-event. Perhaps that will be your saving grace for special events, but not on a daily basis.
Caution: Taking Imodium without diarrhea can leave you constipated.
Q. Any other tips to help manage dreaded diarrhea?
9 of 10
A. If you are a morning runner, drink a warm beverage (tea, coffee, hot water) to stimulate a bowel movement. Allow time to sit on the toilet to do your business prior to exercise.
Also, before you embark on a hard workout, exercise lightly to help stimulate a bowel movement or experiment with training at different times of the day. Perhaps morning exercise, after having had a bowel movement, is preferable to an afternoon workout.
Choose more foods that tend to be naturally constipating, such as bananas, white bread/bagels, white rice and pasta. Exercise with a bathroom nearby or design your running route to include a bathroom.
Before and during exercise, visualize yourself having no intestinal problems. A positive mindset (as opposed to useless fretting) may help control the problem.
