Pooping after eating is normal for many people. It's part of what's called the gastrocolic reflex. It's a normal human function. It's when digestive muscles, nerves, and hormones help move food through your digestive tract. If you regularly poop after every meal, and the stools look normal to you and you don't have any other symptoms, you can relax. It's nothing to worry about.

But if you have other symptoms, like pain or diarrhea, it may be a sign of other digestive conditions like irritable bowel syndrome (IBS).

Here's what you need to know about a normal gastrocolic reflex and when you may need to seek medical care.

What is the gastrocolic reflex?

When you feel the urge to poop, that's your gastrocolic reflex in action. A healthy digestive system relies on the gastrocolic reflex to empty your intestine of stool. This makes room for the next food you eat. It's most common to feel the gastrocolic reflex right after breakfast, but you can feel it after any meal.

It works like this:

• When you eat, your stomach stretches a little bit.

• That activates your large intestine to contract, which moves stool down toward your rectum.

• The stool remains in your rectum until there's enough to excrete or poop.

Start to finish, it takes 10 hours to 3 days for you to digest food and for stool to pass through your gut. To put it differently, today's poop started with food you ate 1 to 2 days ago.

Is there a normal pattern for pooping?

The gastrocolic reflex varies from person to person. Most people feel the urge to go to the bathroom anywhere from 15 to 90 minutes after eating. If you're having a longer meal, it can be normal to find yourself on the toilet shortly after the last bite of food. It's also normal not to feel like you have to go to the bathroom after you eat.

Some foods are strong triggers of your gastrocolic reflex. For example, you may have noticed the urge to poop soon after drinking coffee.

What are the benefits of using the bathroom right after you eat?

If you're pooping after eating, you have a well-functioning gastrocolic reflex. It's important for your gut to get rid of stool to make room for incoming food. Otherwise, your belly will feel uncomfortable and bloated.

If pooping after you eat is normal for you, it means you're following your natural urge to poop, which can help avoid constipation.

What are the risks of ignoring having to poop?

Everyone has to hold it in from time to time. You're in a work meeting, driving on a highway, or at the movies. But if you ignore the urge frequently, you can become constipated. Stool that remains in your colon too long loses too much water. This makes it harder and more difficult to pass.

Ignoring the signal to poop can also have long-term consequences. It can interfere with thegut-to-brain messaging that tells you when it's time to poop. So try to listen to your natural cues and go when you feel the urge.

What is an overactive gastrocolic reflex?

Some people may feel like food goes "right through them" or that they always feel the need to get to the bathroom as soon as possible after they eat.

This can simply be a sign of a "sensitive," "strong," or "overactive" gastrocolic reflex. It all depends on what's normal for you. If you've always had this type of pooping pattern, then it's likely you just have an overachieving gastrocolic reflex.

In general, you don't have to worry about having an overactive gastrocolic reflex if:

• You've always had a strong urge to poop after eating.

• Your stools have a healthy consistency, and you don't have diarrhea or loose or fatty stools.

• You don't have any other symptoms like bloating, stomach pain, or cramping.

• You haven't lost any weight.

• You don't have any blood in your stool.

When should you see a doctor about a hyperactive gastrocolic reflex?

You should talk with a healthcare professional if having an urge to poop right after you eat is new. Certain symptoms can point to conditions like IBS as well as inflammatory bowel disease.

These symptoms may include:

• You feel like you can't make it to the bathroom in time.

• You're worried about leaving the house because of unpredictable stooling patterns.

• Your stool looks different or loose.

• You're having diarrhea.

• There's blood in your stool.

• You're losing weight without trying.

• You're experiencing other symptoms like stomach pain, bloating, gassiness, or cramping.

If you have an overactive gastrocolic reflex, what foods should you avoid?

You don't need to change your diet if you have an overactive gastrocolic reflex. If you naturally have a sensitive gastrocolic reflex, what you eat probably won't make much of a difference on how your colon responds to signals from your stomach.

But if you have IBS, what you eat can impact your symptoms. Experts recommend a diet low in FODMAPs: fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These are types of carbohydrates that aren't easily digested and can cause gas and cramping.

You may want to try avoiding foods that can make symptoms worse, like:

• Fatty foods

• Alcohol

• Spicy foods

• Caffeine
