It varies from person to person and is based on different factors like your diet, age, activity level and if you have any conditions like irritable bowel syndrome (IBS) or inflammatory bowel disease.

And when you have the urge to go, you should be able to sit down on the toilet, and within a few minutes, you should be done (with minimal straining, if any).

Colorectal surgeon Michael Valente, DO, explains how food gets digested and how often you should have a bowel movement.

How long does it take to poop out food?

The time it takes for food to make its way through your digestive system also varies from person to person. It takes different amounts of time for men and women to digest their meals, too.

It can take anywhere from two to five days for food to be fully digested and exit your body. When you eat, food goes through your stomach and small intestine — a process that can take six to eight hours — before entering your large intestine.

Once in your large intestine, it can take around 36 hours for food to be fully digested before you’re ready to have a bowel movement. A bowel movement is when stool, or the matter that’s left over after your digestive system absorbs the nutrients and fluids, exits your body through your rectum and anus.

“If you have a proper diet with good fiber and enough water intake, your bowel movements should be a very short occurrence,” says Dr. Valente.

How much should you poop in a day?

Don’t be alarmed if you don’t have a bowel movement each day.

On average, you should poop about three times a week. But again, it all depends on the individual. If you always poop multiple times a day and your stool is soft and easy to pass, then you’re good.

Aim for a diet full of fiber from whole grains, fruits and vegetables — this will help you have bowel movements pretty regularly. If your diet is lacking in fiber, you may notice you don’t poop as often. Most adults require 25 grams (g)–35 g of fiber per day.

Staying hydrated is also key to healthy bowel movements. Water helps keep food moving through your digestive system and keeps it soft. You may experience constipation if you’re dehydrated. Approximately 64 ounces (or 2 liters) of water per day is recommended.

Another reason you might be constipated? Your age. As you get older factors like reduced mobility and certain medications can affect how often you poop.

Exercise, even walking, can also help keep your bowel movements regular and healthy. By being active, you keep your digestive system working.

If you have a chronic illness like IBS, you may notice your bowel movement pattern can shift from frequent bowel movements to feeling constipated.

“The most common reason for difficulty having a bowel movement is a lack of fiber and fluids in an individual’s diet,” notes Dr. Valente. “Thankfully, difficulties in passing bowel movements are easily corrected by starting and maintaining good eating and drinking habits, as well as an active lifestyle.”

How often should you be pooping?

Again, it depends on each individual. Most people have a bowel pattern that’s regular for them, whether that’s once each morning or three times a day.

But whenever you’re ready to head to the bathroom, the first thing you need to do is leave your electronic devices outside the bathroom, says Dr. Valente. Don’t take the newspaper, your book, your phone or any other device in there with you.

“The bathroom is meant for one reason and one reason only — and that’s to empty your bladder and have a proper bowel movement,” stresses Dr. Valente. “Five minutes really should be the maximum time you spend in the bathroom.”

People may sometimes feel the urge to poop immediately after eating. When this happens, the person may feel as though the food is passing straight through them. However, this is not the case.

In fact, it can take 1–2 days before food finishes its journey through a person’s digestive tract. Therefore, a person who poops shortly after eating is likely to be passing food that they ate a day or two earlier.

The most likely cause of needing to poop right after eating is the gastrocolic reflex. This reflex is a normal involuntary reaction to food entering the stomach. However, the intensity of the gastrocolic reflex can vary among individuals.

In this article, we outline what happens during the gastrocolic reflex and discuss the conditions that can increase its intensity. We also explain the dietary and lifestyle factors that can help reduce the urge to poop right after eating.

The gastrocolic reflex, or gastrocolic response, is a normal involuntary reaction to food entering the stomach.

When food enters this organ, the body releases a hormone that causes the colon to contract. These contractions move previously eaten food further through the digestive system, which can result in the urge to pass stool.

For some people, the gastrocolic reflex is mild, causing no symptoms. For others, the gastrocolic reflex is intense, and the urge to poop after eating can be particularly severe.

Certain health conditions can affect the gastrocolic reflex. For example, irritable bowel syndrome (IBS) can cause a person’s digestive tract to move food through their system at a much faster rate.

Other conditions that could cause a person to pass stool more quickly than average include:

  • food allergies and food intolerances
  • anxiety
  • gastritis
  • celiac disease
  • inflammatory bowel disease (IBD)
  • Crohn’s disease

Each of the above conditions may increase the intensity of the gastrocolic reflex, resulting in an urge to poop soon after eating. They may also give rise to additional digestive symptoms, such as:

  • bloating that subsides after passing gas or stool
  • a frequent need to pass gas
  • abdominal pain or discomfort
  • mucus in the stool
  • diarrhea
  • constipation
  • alternating diarrhea and constipation

Another potential cause of feeling the urge to poop is fecal incontinence. The condition may range in severity from mild to a complete loss of bowel control.

Fecal incontinence is relatively easy to differentiate from the effects of an intense gastrocolic response to food. Specifically, fecal incontinence can occur at any time. It does not only occur after eating.

A person may develop fecal incontinence for several different reasons, including:

  • diarrhea
  • nerve damage in the rectum
  • damaged muscles in the rectum
  • damaged rectal walls
  • rectocele
  • rectal prolapse

People who are concerned that they may have fecal incontinence should visit their doctor for a diagnosis. A doctor can explain the many different ways to treat and manage fecal incontinence.

An episode of diarrhea following a meal is unlikely to relate to the person’s gastrocolic reflex.

Diarrhea is a common condition that typically only lasts a day or two. However, diarrhea that lasts for a week or more could indicate an underlying health issue.

Some common causes of persistent diarrhea include:

  • excessive consumption of artificial sweeteners and other laxatives
  • foodborne bacteria and parasites
  • food intolerances
  • food allergies
  • digestive disorders
  • viral infection
  • previous abdominal surgery, such as gallbladder removal

The gastrocolic reflex is a normal reaction to food entering the stomach. In most cases, feeling the urge to poop after eating does not warrant a visit to the doctor.

However, a person should see their doctor if they experience the following:

  • intense and frequent gastrocolic responses to food
  • diarrhea lasting longer than 2 days
  • additional gastric symptoms

The above symptoms could indicate a possible underlying health issue.

As the gastrocolic reflex is a normal bodily reaction, it does not technically require treatment. However, there are steps that people can take to help reduce the intensity of the gastrocolic reflex and the associated urge to poop.

Seek treatment for underlying digestive conditions

People should see a doctor if other gastric symptoms accompany the urge to poop after eating.

Depending on the duration and severity of these symptoms, a doctor may carry out tests to diagnose any underlying health conditions.

If a condition is present, treating it may help reduce the intensity of the gastrocolic reflex.

Changing the diet

Share on PinterestA change in diet may help treat an intense gastrocolic response.

Some foods are more likely than others to cause an intense gastrocolic response. These include:

  • fatty or greasy foods
  • dairy products
  • foods high in fiber

Keeping a food diary can help a person identify foods that may be intensifying their gastrocolic response. The diary should contain a record of the foods that the person eats, as well as their digestive response to the foods.

Once the person has identified a possible trigger food, they should temporarily avoid the food to see whether their symptoms improve.

Managing stress

For some people, stress can increase the intensity of the gastrocolic reflex. These individuals may benefit from activities that help reduce stress. Examples include exercise and meditation.

Passing stool immediately after a meal is usually the result of the gastrocolic reflex, which is a normal bodily reaction to food entering the stomach.

Almost everyone will experience the effects of the gastrocolic reflex from time to time. However, its intensity can vary from person to person. Certain lifestyle factors can help reduce the urge to poop following a meal.

People should see a doctor if they frequently experience diarrhea or other gastric symptoms following a meal. These symptoms could indicate an underlying health issue that requires medical attention.

How long does it take to poop out food you just ate?

After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.

What causes rapid bowel movement after eating?

Dumping syndrome is a condition in which food, especially food high in sugar, moves from your stomach into your small bowel too quickly after you eat. Sometimes called rapid gastric emptying, dumping syndrome most often occurs as a result of surgery on your stomach or esophagus.

Can food pass through you in 2 hours?

Generally speaking, it takes about 2 to 4 hours for food to move from your stomach to your small intestine. The exact amount of time can depend on several factors, such as the composition and size of your meal, your hormones, and your sex. Women tend to digest food more slowly than men.
