If you’re always running to the restroom after every meal, you might think you’re digestive system is super efficient. Staying regular is incredibly important, after all. But, how often you poop—and how soon it happens after mealtimes—actually varies from person to person.

Some people report pooping once or twice a day, but it really depends on how well you go, says Christine Lee, MD, a gastroenterologist at Cleveland Clinic. “If the quality of the bowel movement is not great, then some people will need to go two to three times back to back in a matter of one to two hours.”

Even though you’re going to the bathroom multiple times, this would still “only equal one good-quality bowel movement,” Dr. Lee says.

You may find that some of those trips to the loo happen just after you’ve eaten, but that usually shouldn’t worry you too much, she explains. Your body has a natural reflex that determines how soon you’ll poop after eating. Here’s what you should know.

Why Do You Sometimes Need to Poop After You Eat?

The gastrocolic reflex controls how what you eat moves through the lower gastrointestinal tract. So, when you feel like you need to poop after eating, that’s why.

This reflex occurs when you eat. Ingesting food causes the stomach to stretch, which stimulates the bowel, resulting in a bowel movement, explains Pratima Dibba, MD, a board-certified gastroenterologist at Medical Offices of Manhattan and contributor to LabFinder.

The gastrocolic reflex is a normal process, so there’s usually nothing to worry about if you need to poop after meals—as long as your stool is healthy, Dr. Dibba says. That means it’s solid and easy to pass. If your stool is loose, resembling diarrhea, it could signal a GI condition or malabsorption, where you have trouble absorbing the nutrients from food, she explains.

While you might feel like what you eat just goes right through you if you’re rushing to the bathroom right after eating, that’s not likely the case. Everyone’s digestive system moves at a different pace. Research shows that it can take between 10 and 73 hours for food to pass through your system and cause you to poop.

What Influences Your Gastrocolic Reflex?

The gastrocolic reflex may work a little differently for everyone. Foods may move through your colon more quickly if you have a digestive disorder, like irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD), research suggests. Anxiety, celiac disease, or food allergies or intolerances might also cause an overactive gastrocolic reflex.

Other reasons you might need to poop after eating are if your colon was already full of stool and “ready to unload with any stimulation,” Dr. Lee says. Some people also might have weak anorectal muscles or poor control over these muscles, which could make them feel like they need to poop more frequently.

Why You Should Pay Attention to Your Poop

The gastrocolic reflex is usually “inconsequential,” Dr. Dibba says. “It’s OK to have bowel movements immediately after eating.”

But the consistency of your poop matters. Healthy bowel movements are sausage-shaped, soft, smooth, and easy to pass, according to the Bristol Stool Chart.

If you have diarrhea frequently after eating, it’s likely not related to your gastrocolic reflux. It could be a virus, parasite or bacterial infection, according to Harvard Health. You might also have a food allergy or intolerance or a medical condition, like IBD or celiac disease.

When to Worry About Pooping After Meals

You can’t stop your gastrocolic reflex from doing its job. But, if it’s embarrassing or annoying to head straight to the bathroom after eating, you should pay attention to what might be triggering it.

For instance, do you notice you need to poop soon after eating fiber-rich foods or dairy? Or greasy, fried foods? If so, consider avoiding these items or choosing the right times to eat them, when a bathroom break is possible.

Stress can also trigger the gastrocolic reflex, so taking steps to relax and limit stress could help, too.

If you seem to frequently have diarrhea after eating, talk to your doctor, Dr. Dibba says. Also, call your doctor if you have other symptoms, like abdominal pain or weight loss, or if it’s affecting your quality of life.

“You should see a doctor for any symptoms that are worrisome or bothersome to you,” Dr. Lee says.
