Frequent need to defecate? 9 main causes

Feces differ from person to person. People may have a bowel movement several times a week or several times a day. A sudden change in the frequency of bowel movements may be due to stress, a change in diet or exercise, or an underlying medical condition. If the stool returns to normal after a few days, there is no need to worry. However, consistently significantly larger than normal bowel movements may indicate an underlying condition that may require treatment.

Here are nine possible causes of the frequent urge to defecate. Here is also information on treatment options and when to seek medical attention for gastrointestinal discomfort.

Main causes of the frequent need to defecate

Changes in diet and alcohol consumption can affect a person’s bowel habits. Here are some potential causes of pooping more often than normal.

1 Changes in diet

A change in diet can lead to a change in bowel movements. For example, consuming more fiber helps food pass through the digestive system. Therefore, a person who adds more fruits, vegetables, and whole grains to his diet may find that he needs to poop more often.

2 Alcohol consumption

Alcohol can have an immediate effect on the amount of stool a person passes. High-alcohol drinks can slow down your digestive system, while low-alcohol drinks can speed it up. Low-alcohol beverages include beer and wine. After consuming these drinks, people may feel like pooping more often or faster. This effect should wear off once the alcohol leaves the body.

3 Exercise

A 2017 review suggests that low-intensity exercise can decrease the time it takes for food to pass through the intestine. This could result in more regular bowel movements. Some people report the need to defecate during or immediately after physical activity. Intense exercise has a greater impact on the body and can cause the following symptoms:

stomach ache

4 stress

Stress can have a huge impact on gut function and health. It speeds up the movement of food through the large intestine, while persistent stress could trigger the need to empty the intestines more frequently. People experiencing acute stress or anxiety may also feel an increased need to go to the bathroom. This is due to the body’s gut-brain axis, the network that connects the central nervous system with the nerves of the gastrointestinal (GI) tract. The gut-brain axis is responsible for the “butterflies” that a person feels in the stomach when anxious.

5 diarrhea

The definition of diarrhea is as follows: at least three loose, liquid stools per day. Other symptoms may include:

– an urgent need to go to the bathroom
– loss of bowel control
– abdominal pain
– nausea
Diarrhea can occur as a result of a viral, bacterial, or parasitic infection. The exact cause may not be obvious in some cases. Most cases of diarrhea should clear up within 4 days. In the meantime, it is best to rest and drink plenty of fluids to avoid dehydration.

6 periods

People are more likely to experience abdominal pain and diarrhea in the days leading up to their period. People who reported emotional symptoms and fatigue before or during their period were more likely to experience multiple gastrointestinal symptoms. The researchers conclude that this may be due to common pathways between the brain, gut and hormones. These symptoms usually go away once your period ends.

7 Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder that can cause the following symptoms:

– stomach cramps
– swelling
– Diarrhea
– constipation
The cause of IBS isn’t clear, but some possible reasons include:

– hypersensitivity of the nerves within the intestine
– food passes through the intestine too quickly or too slowly
– stress
– Genetic factors.

Common dietary triggers of IBS are:

– caffeine
– dairy products
– carbonated drinks
food intolerances

8 food intolerances

Food intolerances occur when a person cannot properly digest certain foods.

Symptoms include:

– Diarrhea
– abdominal pain or discomfort
– nausea
– vomiting

These are some examples of food intolerances

– lactose intolerance, when a person cannot break down lactose found in milk and milk products
– fructose intolerance, in which a person cannot break down fructose, a fruit sugar
– Non-celiac gluten sensitivity, which causes the inability to break down the gluten proteins contained in cereals.

9 Crohn’s Disease

Crohn’s disease is an inflammatory bowel disease (IBD) that causes chronic inflammation of the digestive tract. Symptoms vary from person to person, in part depending on which part of the digestive tract is affected. These are some of the most common symptoms:

– an urgent need to empty the bowels
– a feeling of incomplete emptying of the intestines
– persistent diarrhea
– constipation
– rectal bleeding
– cramps and abdominal pain

There is no definite cause for Crohn’s disease, although genetic and environmental factors may play a role.


Treatment for more frequent urination depends on the underlying cause. If a person has an underlying medical condition, a doctor will need to treat them to relieve symptoms.

However, people can also benefit from more general treatments.

For example, the following options might help someone with acute diarrhea:

– over-the-counter antidiarrheal medications
– sports drinks or rehydration solutions to help prevent dehydration
– avoid alcohol, caffeine and sweeteners
– avoid fatty, spicy or dairy foods.
A person who thinks their diet is causing them to have more frequent bowel movements may want to keep a food diary. This can help her recognize foods that may be affecting her bowel habits. Once the person has identified the trigger foods, they should avoid or limit them.

When to see a doctor

The need to defecate more often than normal is not necessarily a cause for concern. However, a person should see a doctor if he experiences any of the following symptoms:

– abdominal pain
– diarrhea that lasts more than 2 days
– defecate 6 or more times in 24 hours
– black or bloody stools
– nausea or vomiting
– persistent fever
– symptoms of dehydration
These symptoms may indicate a serious underlying medical problem.


It is not always possible to prevent the triggers of more frequent bowel movements. However, the following tips can help reduce the risk of digestive problems.

– Increase fiber intake

A person who consumes a lot of fiber can promote more regular bowel movements. People should eat more vegetables, whole grains and legumes.
It is important to gradually increase your intake of dietary fiber and drink plenty of water. This will help prevent constipation.

– Reduces stress

People experiencing bowel problems due to stress may benefit from the following activities:

– physical exercise
– meditation
– relaxation therapy
– talk therapy
– Practice good hygiene

The following tips can reduce the risk of contracting bacteria and viruses that can cause stomach upset and diarrhea:

– wash your hands well after going to the bathroom
– wash hands thoroughly before preparing and eating food
– cook the meat well
– avoid sharing personal items, such as: kitchen utensils, toothbrushes, razors, towels
