Can Diarrhea Be Brought On By Physical Activity?

Exercise can cause various gastrointestinal (GI) symptoms, which can range in severity and impact athletic performance. Losing water and fluids during exercise can lead to dehydration and diarrhea, which can be particularly severe if targeting the lower abs. It is important to get plenty of healthy fluids before, during, and after workouts to prevent these issues.

Diarrhea is a common complaint during working out, especially among runners, elite or endurance athletes, and people who engage in intense exercise. Studies suggest that 30-50 of athletes and active people experience digestive distress during or after exercise. Diarrhea can be caused by walking, running, and other workouts, with the harder the run, the more severe the diarrhea can be. Repetitive motion may contribute to symptoms such as diarrhea and urgency, or even GI bleeding.

Ischemic conditions, such as fluctuating digestive hormones, reduced digestive blood flow, and abrupt movements, can also cause diarrhea after working out. Gut ischemia is the main cause of nausea, vomiting, abdominal pain, and bloody diarrhea, with the frequency being almost twice as high during running than other activities.

Why do I get diarrhea after I run?

The cause of runner’s diarrhea isn’t clear. Contributing factors likely include 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. What is clear is that food moves more quickly through the bowels of athletes in training.

Often, simple dietary changes can help prevent runner’s diarrhea:

• At least one day before running, limit or avoid high-fiber and gas-producing foods, such as beans, bran, fruit and salad. If you run every day, experiment to find a tolerable level of fiber. Otherwise, simply eat those foods after you run.
• At least one day before running, limit or avoid sweeteners called sugar alcohols (isomalt, sorbitol, others) — most often found in sugar-free candies, gum and ice cream.
• For three to six hours before running, limit or avoid caffeine and high-fat foods.
• For at least two hours before running, don’t eat anything at all.
• Before, during and after running, drink plenty of fluids. Dehydration can lead to diarrhea. Avoid warm liquids, however, which can speed food through the digestive tract.
• While running, use caution with energy gels and energy bars. In some people, these products can contribute to diarrhea. And especially avoid introducing a new gel or bar on race day.
• If you’re lactose intolerant, switch to lactose-reduced or lactose-free milk and milk products.
• Avoid nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin IB, others) or naproxen (Aleve). Both have been shown to increase the incidence of gastrointestinal complaints.

Why do I have watery diarrhea?

Watery diarrhea. Watery diarrhea happens when your colon is unable to absorb enough water and electrolytes from your poop and/or when it’s secreting more than it’s absorbing. The osmotic type is caused by poorly absorbed nutrients that draw extra water into your colon. (This is how osmotic laxatives work.) Meanwhile, secretory diarrhea represents a wide variety of diseases that can cause watery diarrhea.

Fatty diarrhea. Sometimes, excess fat in your poop changes the consistency to diarrhea. This can happen when your body has trouble breaking down and absorbing fats, or when bacteria in your gut produce excessive fatty acids. Fatty diarrhea may be less frequent but with greater volume. It may be smellier than normal and may leave a visible oil residue in the toilet. It may come with nausea, indigestion and weight loss.

Inflammatory diarrhea. Inflammatory diarrhea is caused by inflammation in your colon ( colitis ). Inflammation affects the mucous lining of your colon ( mucosa ). It causes swelling and impairs the colon’s ability to absorb. Inflammatory diarrhea tends to come out more frequently and in smaller amounts. It may be accompanied by stomach pain, fever or bleeding. Inflammatory conditions that can cause chronic diarrhea include:

Why am I having diarrhea when I’m not sick?

• Exposure to viruses, bacteria or parasites. This is a major risk factor for sudden onset of diarrhea.
• Diet. Certain foods or drinks, including coffee, tea, dairy products, or foods containing artificial sweeteners can cause diarrhea in some people.
• Medicines. Some medicines, such as antibiotics, laxatives, magnesium supplements, antidepressants, NSAIDs, chemotherapy and immunotherapy, can cause diarrhea.

Complications. Diarrhea can cause dehydration, which can be life-threatening if not treated. Dehydration is particularly dangerous in children, older adults and those with weakened immune systems.

If you have symptoms of serious dehydration, seek medical help.

Can movement cause diarrhea?

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. This could be the reason why runners experience diarrhea during races and intense workouts.

Can exercise trigger IBS?

Exercise may trigger IBS. However, this generally happens with intense, long lasting forms of exercise, such as long-distance running or cycling.

According to 2023 research, strenuous exercise and endurance sports may cause exercise-induced gastrointestinal symptoms (Ex-GIS). In previous studies, researchers found rates as high as 70% among athletes. The symptoms of Ex-GIS may include:

• Bloating
• belching
• heartburn
• regurgitation of food
• flatulence
• bowel urgency
• abdominal pain
• diarrhea

Can inactivity cause diarrhea?

In a study published today in the American Gastroenterological Association (AGA) journal Clinical Gastroenterology and Hepatology, researchers found that a high body mass index (BMI) and lack of physical activity were associated with an increase in GI symptoms such as stomach pain, diarrhea, constipation and irritable …

Bethesda, Maryland (Oct. 3, 2005) Physical activity may help reducegastrointestinal (GI) symptoms in people who are obese. In a studypublished today in the American Gastroenterological Association (AGA)journal Clinical Gastroenterology and Hepatology, researchers found that a high body mass index (BMI) and lack ofphysical activity were associated with an increase in GI symptoms suchas stomach pain, diarrhea, constipation and irritable bowel syndrome(IBS).

Obesity is a chronic disease that has become a major health problem inthe United States and around the world. In fact, many patients who areseen by gastroenterologists are overweight or obese. Over the last 20years, obesity has emerged as the most important nutrition problem inthe United States.

Researchers from the University of Washington in Seattle and theUniversity of Minnesota in Minneapolis found that obese people whoincorporated some form of physical activity into their routine sufferedless from GI symptoms than others who were inactive. High BMI wasassociated with an increase in symptoms of IBS, abdominal pain anddiarrhea and binge eating was associated with an increase in abdominalpain, constipation and bloating. Of those participating in the study, more than 13 percent had IBS and nearly 6 percent were binge eaters. Onaverage, participants in this study were classified as obese, with anaverage BMI of 33.

Can exercise cause diarrhea?

As people exercise, their bodies respond in several complex ways. Some of these responses can affect their gastrointestinal system’s functions, including digestion and waste excretion. The bodily responses to exercise can include :

• Redirected blood flow: When a person exercises, blood flows to their muscles, limbs, and circulatory system instead of their digestive system. This can cause diarrhea.
• Hormonal activity: Chemicals called hormones regulate different bodily functions. During exercise, a person’s body releases some hormones that reduce the capacity of the gastrointestinal system.

Exercise can also affect the organs in a person’s abdomen through physical effects such as:

• Jarring, jolting, or sudden impacts
• a person’s body position
• friction

Can overtraining cause diarrhea?

Diarrhea and digestive conditions such as leaky gut are prevalent in people who do strenuous exercise for long periods. This includes swimmers, cyclists, and triathletes. Vigorous activities such as aerobics, dancing, and skiing can also cause digestive upset.

Losing water and fluids through exercise can cause dehydration and diarrhea. Get plenty of healthy fluids before, during, and after your workouts. Replenish lost fluids with water and healthy drinks such as coconut water, broth, and fruit juices.

Diarrhea and other digestive concerns often occur during pregnancy, especially as your due date nears. If you’re already experiencing digestive issues during pregnancy, working out may exacerbate your symptoms.

Is it normal to poop a lot after running?

“Walking and jogging tend to increase gastric motility and gastric emptying in everyone; this is a physiologic response,” Dr. Smith says. “Movement gets the digestive system moving a little more quickly than if you’re sitting still. While it may be inconvenient, it’s never in and of itself a dangerous sign.”

Changes in your stool can help identify problems in the digestive system. So, any pooping that’s out of the ordinary might cause you concern. If you’re a runner, you might wonder why being on the go, causes you to go. In other words, why does running make you poop? And, is that normal? Devin RH Smith, MD, UnityPoint Health, helps us understand why activity stimulates gastric motility and things you can try to keep running and bowel movements on course.

Why Does Running Make You Poop?. Dr. Smith assures runner’s trot, or runner’s diarrhea, is normal.

” Walking and jogging tend to increase gastric motility and gastric emptying in everyone; this is a physiologic response,” Dr. Smith says. “Movement gets the digestive system moving a little more quickly than if you’re sitting still. While it may be inconvenient, it’s never in and of itself a dangerous sign.”

Can lack of rest cause diarrhea?

“Sleep deprivation increases your risk for a long list of health problems, such as mood swings, gastrointestinal symptoms (abdominal pain, gas, diarrhea, constipation, nausea, vomiting), headaches and joint pain, blood sugar and insulin system disruption, high blood pressure, seizures, and hallucinations.

“Sleep deprivation can also create problems during sleep, causing sleep apnea, restless legs, and other sleep disorder symptoms (getting enough sleep will correct these problems). Some people show more decline in performance than others, which may reflect an inherited trait or sensitivity to sleep loss.”

• Being awake for 17 hours mimics a blood alcohol concentration, or BAC, of 0. 05%, which is the level some countries use for drunk driving violations.
• Being awake for 24 hours is like having a BAC of 0. 10%, which is above the U. S. drunk driving level of 0. 08.
