Running is a popular form of exercise that offers numerous health benefits, including improved cardiovascular health, better mental health, and weight loss. However, many runners experience an unpleasant side effect of running: the urge to poop. This phenomenon, known as runner’s diarrhea, is a common problem among runners, especially those who engage in long-distance running. But why does running make you poop, and what can you do to prevent it?
The answer to this question is not entirely clear, but several factors can contribute to runner’s diarrhea. One factor is the physical jostling of the organs that occurs during running, which can stimulate the bowels and increase the urge to poop. Other factors include decreased blood flow to the intestines, changes in intestinal hormone secretion, increased amount or introduction of new food, and pre-race anxiety and stress. Understanding the runner’s gut and the factors that influence bowel movements can help runners manage this unpleasant side effect of running.

- Understanding the runner’s gut and the factors that influence bowel movements can help runners manage runner’s diarrhea and prevent it from interfering with their exercise routine.
Understanding the Runner’s Gut
As a runner, you may have experienced the sudden urge to poop during or after a run. This phenomenon, commonly known as “runner’s trots” or “runner’s diarrhea,” is not uncommon among runners. In this section, we will explore the reasons behind this uncomfortable experience.
The Digestive System and Running
The digestive system plays a vital role in the body’s functioning, and it can be affected by various factors, including exercise. When you run, the body directs blood flow to the muscles, which can decrease blood flow to the digestive system. This decrease in blood flow can cause digestive issues, such as cramping, bloating, and diarrhea.
The Role of Physical Jostling
Another factor that can contribute to runner’s trots is physical jostling. Running involves repetitive impact on the body, which can shake and jostle the internal organs, including the intestines. This shaking can speed up the movement of stool through the intestines, leading to an urgent need to poop.
It’s essential to note that not all runners experience runner’s trots, and the severity and frequency of symptoms can vary. Several factors can contribute to the likelihood of experiencing runner’s trots, including:
- Running intensity and duration
- Pre-run diet and hydration
- Pre-existing digestive conditions
In conclusion, the digestive system is sensitive to exercise, and running can cause physical jostling that can lead to digestive issues, including runner’s trots. Understanding the factors that contribute to this phenomenon can help runners take steps to prevent and manage these uncomfortable symptoms.
Factors That Influence Bowel Movements
Bowel movements are a natural part of the digestive process, and many factors can influence their frequency and consistency. Running is one activity that can stimulate bowel movements, leading to the phenomenon known as “runner’s trots.” Here are some of the factors that can influence bowel movements:
Dietary Factors
Diet plays a significant role in bowel movements, and what you eat can affect the frequency and consistency of your stools. Eating a diet high in fiber can promote regular bowel movements, while consuming too much sugar and fat can lead to constipation. Some sweeteners, such as sorbitol and xylitol, can also cause diarrhea in some people. Caffeine and alcohol can also have a laxative effect on the body.
Hydration and Dehydration
Staying hydrated is essential for maintaining healthy bowel movements. Dehydration can lead to constipation, while drinking enough water can help soften stools and promote regularity. However, drinking too much water during exercise can also lead to diarrhea, so it’s important to find the right balance.
The Role of Stress and Anxiety
Stress and anxiety can also influence bowel movements, and many people experience digestive issues during times of high stress. The “fight or flight” response triggered by stress can cause the body to divert blood away from the digestive system, leading to constipation or diarrhea. Relaxation techniques such as deep breathing or meditation can help alleviate stress-related digestive issues.
In conclusion, many factors can influence bowel movements, including diet, hydration, stress, and anxiety. By paying attention to these factors and making adjustments as needed, you can help promote healthy bowel movements and reduce the risk of digestive issues during exercise.
Common Symptoms and Conditions
Running is an excellent way to stay fit and healthy, but it can also lead to some unpleasant side effects, including diarrhea, abdominal pain and cramping, nausea, and other gastrointestinal (GI) distress. In this section, we will discuss the most common symptoms and conditions that runners experience.
Runner’s Diarrhea
Runner’s diarrhea, also known as runner’s trots or runner’s colitis, is a condition that affects many runners. It is characterized by loose, watery stools that occur during or after a run. The exact cause of runner’s diarrhea is not known, but it is thought to be related to the physical jostling of the organs, decreased blood flow to the intestines, changes in intestinal hormone secretion, increased amount or introduction of new food, and pre-race anxiety and stress.
Symptoms of runner’s diarrhea can include frequent bowel movements, urgency to have a bowel movement, abdominal cramping, and nausea. In some cases, runners may also experience dehydration, electrolyte imbalances, and fatigue.
Abdominal Pain and Cramping
Abdominal pain and cramping are common side effects of running, especially for long-distance runners. This pain can be caused by a variety of factors, including dehydration, electrolyte imbalances, and changes in blood flow to the intestines.
Symptoms of abdominal pain and cramping can include a dull ache or sharp pain in the stomach, bloating, and nausea. In some cases, runners may also experience diarrhea or constipation.
Nausea and Other GI Distress
Nausea and other GI distress are also common side effects of running. These symptoms can be caused by a variety of factors, including dehydration, electrolyte imbalances, and changes in blood flow to the intestines.
Symptoms of nausea and other GI distress can include a feeling of fullness in the stomach, bloating, belching, and vomiting. In some cases, runners may also experience diarrhea or constipation.
In conclusion, while running is an excellent way to stay fit and healthy, it can also lead to some unpleasant side effects. If you experience any of the symptoms discussed in this section, it is important to take steps to prevent or treat them. This may include staying hydrated, eating a balanced diet, and taking rest days when needed.
Pre-Race and Race Day Considerations
Preparing for a race can be stressful, and anxiety can trigger the urge to defecate. In this section, we will discuss various factors that can affect your bowel movements before and during a race.
Pre-Race Anxiety
Pre-race anxiety is a common issue for many runners. The excitement, nervousness, and pressure of the event can cause stress, which can lead to gastrointestinal issues. To reduce anxiety, try to arrive at the race location early, so you have time to get familiar with the surroundings and mentally prepare for the race. You can also try relaxation techniques such as deep breathing, yoga, or meditation.
Bathroom Stops and Clothing Choices
Bathroom stops are an essential consideration for runners. It is recommended to use the bathroom at least 30 minutes before the race starts. If you need to go again, plan to arrive at the race location early to allow time for multiple bathroom breaks.
Clothing choices can also affect bowel movements. Tight clothing can put pressure on the abdomen, which can lead to discomfort and bowel movements. Loose-fitting clothing can be more comfortable and allow for better airflow.
Nutrition and Hydration
What you eat and drink before and during the race can affect your bowel movements. It is crucial to stay hydrated, but too much water can cause diarrhea. Energy gels and bars can provide the necessary nutrients, but they can also cause gastrointestinal distress. It is recommended to try different energy gels and bars during training to see which ones work best for you.
Additionally, it is essential to avoid foods that are high in fiber, fat, and sugar, as they can cause gastrointestinal issues. Instead, choose foods that are easy to digest, such as bananas, oatmeal, and toast.
In conclusion, pre-race and race day considerations are crucial for runners. By managing pre-race anxiety, planning bathroom stops, choosing appropriate clothing, and being mindful of nutrition and hydration, runners can reduce the risk of gastrointestinal issues during the race.
Prevention and Management
There are several ways to prevent and manage runner’s diarrhea, including dietary adjustments, exercise and warm-up routines, and medication and supplements.
Dietary Adjustments
One of the most effective ways to prevent runner’s diarrhea is to make dietary adjustments. Avoid high-fiber and gas-producing foods such as beans, bran, fruit, and salad at least one day before running. Instead, opt for easily digestible foods like rice, pasta, and bread. It is also important to stay hydrated before, during, and after exercise.
In addition, taking a fiber supplement can promote bowel regularity. However, it is recommended to reduce or stop fiber intake a couple of days before race day to avoid any digestive issues.
Exercise and Warm-Up Routines
Proper exercise and warm-up routines can also help prevent runner’s diarrhea. Start with a light warm-up to get your body ready for exercise. This can include stretching, jogging, or walking. Gradually increase the intensity of your workout to avoid any sudden jolts that can trigger the urge to defecate.
It is also important to listen to your body and take breaks when needed. If you feel the urge to go, stop and take care of it before continuing your workout.
Medication and Supplements
If dietary adjustments and exercise routines are not enough, medication and supplements can also help manage runner’s diarrhea. Peppermint oil has been shown to have a calming effect on the digestive system and can reduce symptoms of diarrhea. Aspirin can also help reduce inflammation and alleviate diarrhea symptoms.
However, it is important to consult with a healthcare professional before taking any medication or supplements to ensure that they are safe and effective for you.
By following these prevention and management techniques, you can reduce your risk of runner’s diarrhea and continue to enjoy your workouts without any interruptions.
When to Seek Medical Attention
