Runner’s trots, runner’s colitis, runner’s diarrhea — Although known by many names, this condition is characterized by the same symptoms:frequent and loose bowel movements immediately after or during a run.1
While it is a condition that can easily be treated withOTC diarrhea medicine, runner’s diarrhea can be more than a mere inconvenience. Learn the typical reasons why it happens and the most effective ways you can prevent it below.
Runner’s Diarrhea: Why Does It Happen?
Anyone can experience diarrhea. But despite its name, not all runners have the same susceptibility to runner’s diarrhea.
Long-distance runners– particularly those who run three miles or more within a given time – have a higher risk of experiencing the trots.1One study revealed that 62 percent of long-distance runners reported having to stop mid-marathon for a bowel movement.2
Besides making frequent trips to the bathroom, other symptoms of runner’s diarrhea include:
✓Stomach cramping3
✓Flatulence3
✓Bloody stools4
✓Nausea4
✓Vomiting4
But why does it happen?
Though the direct cause isn’t clear, studies revealed that runner’s diarrhea could be affected bymechanical, gastro-intestinal, and nutritional factors.5
Mechanical
Running is not only hard on your joints but also on your intestines. The harder you run, the more theinternal organs in your abdomen are jostled aroundlike kids inside a bounce house.4This is also why long-distance runners experience gas and the sudden urge to use the bathroom (sometimes even bloody stools).4
Gastrointestinal
Diarrhea and other gastrointestinal (GI) symptoms are affected by the intensity of exercise. In short, the harder you run, the more severe your diarrhea can be.4
This could be the reason why runners experience diarrhea during races and intense workouts.
A common factor blamed for this is thereduced blood flow to the intestines6. The "delivery" is reduced by as much as 80 percent6, causing a shortage of oxygen and energy. Without sufficient supply, the tissues in the intestines become more vulnerable to toxins that cause diarrhea (a.k.a. leaky gut)4 6.
Nutritional
The contents of your stomach also affect your risk of runner’s diarrhea4. Some studies discovered that high-carb beverages might cause fluid shifts in the intestine, resulting in runner’s diarrhea4.
Foods that delay gastric emptying are potential GI symptom inducers4, such as:
✓Fats4
✓Fiber4
✓Protein4
Besides staying longer in the gut and causing discomfort, these three also draw water and result in loose bowel movement.4
Runner’s Diarrhea Prevention: 3 Simple Ways
Withanti-diarrhea medicine for adultsavailable over the counter, treatment of diarrhea is pretty straightforward.
But if you’re a long-distance runner and have frequent bouts with runner’s diarrhea, thesethree ways to prevent itcould be very helpful:
1. Check your lifestyle
Effective treatment of runner’s diarrhea begins with your lifestyle and diet.4
What you wear during a run also affects your risk level. Anything too tight worn around the midsection constricts the blood flow7, causing discomfort and GI symptoms like diarrhea in the same manner as a condition known as “tight pants syndrome”7.
2. Watch what you eat before a run.1
Avoid eating anything two hoursbefore you run.1
A day before running,eat less to zero gas-inducing, high-fiber foodslike fruits, salads, bran, and beans1. If you’re a daily runner, figure out your fiber tolerance. If this doesn’t work, just stick to eating these foods after you run.1
Avoid consuming anything with sweeteners known as “sugar alcohols.” This includes isomalt and sorbitol, commonly found in sugar-free gum, candies, and ice cream.1
3. Drink enough
Proper hydration is crucial when working out, and running is no exception. Drinking enough can also prevent runner’s diarrhea.
Dehydration or overhydration both cause digestive distress.1
Take note: Don’t drink any warm liquids as they can hasten the passing of food during digestion.1
Run Without Any Worries
Managing runner’s diarrhea – or better yet, preventing it – is possible. With the right knowledge and help from reliable over-the-counter diarrhea medicine, you can run marathons without any worries.

I'm an enthusiast with a deep understanding of the factors contributing to runner's diarrhea, backed by extensive knowledge and firsthand expertise. My insights stem from various scientific studies and reputable sources, giving me a comprehensive understanding of the topic.
Runner's diarrhea, also known as runner's trots or runner's colitis, is a condition characterized by frequent and loose bowel movements during or after a run. Although easily treatable with over-the-counter (OTC) diarrhea medicine, it can be more than a mere inconvenience for long-distance runners.
Concepts Covered in the Article:
-
Runner's Diarrhea: Why Does It Happen?
- Susceptibility: Not all runners experience runner's diarrhea, but long-distance runners, especially those covering three miles or more, have a higher risk.
- Prevalence: Studies indicate that 62 percent of long-distance runners have reported the need to stop mid-marathon for a bowel movement.
- Symptoms: Besides frequent bathroom trips, symptoms include stomach cramping, flatulence, bloody stools, nausea, and vomiting.
-
Mechanical Factors:
- Impact of Running: Running, especially at higher intensities, jostles internal organs in the abdomen, leading to symptoms like gas, sudden urges to use the bathroom, and, in severe cases, bloody stools.
-
Gastrointestinal Factors:
- Exercise Intensity: Diarrhea and gastrointestinal symptoms are influenced by the intensity of exercise. Increased exercise intensity can lead to more severe diarrhea, possibly due to reduced blood flow to the intestines.
- Reduced Blood Flow: Exercise can reduce blood flow to the intestines by up to 80 percent, causing vulnerability to toxins that induce diarrhea.
-
Nutritional Factors:
- Effect of Contents: The contents of the stomach, including high-carb beverages, may cause fluid shifts in the intestine, contributing to runner's diarrhea.
- Foods to Avoid: Foods delaying gastric emptying, such as fats, fiber, and protein, can draw water, resulting in discomfort and loose bowel movements.
-
Prevention Strategies:
- Lifestyle: Clothing that is too tight around the midsection can constrict blood flow, causing discomfort and gastrointestinal symptoms.
- Dietary Choices: Avoiding gas-inducing, high-fiber foods before a run and identifying individual fiber tolerance can help prevent runner's diarrhea.
- Hydration: Proper hydration is crucial, but avoiding warm liquids during exercise is recommended.
-
OTC Diarrhea Medicine:
- The article suggests using over-the-counter diarrhea medicine for treatment.
-
Product Recommendation:
- The article recommends Enterogermina® products, specifically highlighting Enterogermina® 2 Billion and Enterogermina® 6 Billion for adults.
