Why Does Coffee Make You Poop? – From a Coffee Addict

86 / 100

There are many things in life that we don’t fully understand. Why does the sun rise in the morning? Why do we have to pay taxes? And, most importantly, why does coffee make you poop?

As a coffee addict, I’ve been trying to figure out this mystery for years. And while I haven’t been able to find a definitive answer, I’ve come up with a few theories.

  • The caffeine in coffee is a diuretic, which means it increases urine production. This can lead to dehydration, which can cause constipation.
  • Coffee also stimulates the gut and promotes peristalsis, the contractions that move food through your digestive system. This can speed up bowel movements.
  • Coffee contains oils and acids that can irritate the digestive tract and may stimulate the bowels.
  • Some people are just more sensitive to the effects of coffee than others. If you have a family history of Crohn’s disease or ulcerative colitis, you may be more likely to experience gastrointestinal issues after drinking coffee.

Why Does Coffee Make You Immediately Poop?

Here’s the science: It turns out there’s a physiological reason coffee makes some people poop. “Coffee is a mild diuretic, meaning it helps you relieve water retention by making you urinate more frequently,” explains Dr. Scott Auerbach, an emergency medicine physician at NYU Langone Health.

Dehydration can lead to constipation, because when you don’t have enough fluids in your system, your stool can become hard and dry, making it difficult to pass. (FYI: You should be drinking six to eight glasses of water a day.)

Caffeine also acts as a stimulant to the digestive system. “It increases gut motility—the movement of food and waste through your intestines—by relaxing the muscles in your colon and stimulating the nerves that control peristalsis,” says gastroenterologist Roshini Rajapaksa, MD, assistant professor of medicine at NYU Langone Health. Peristalsis is the involuntary muscle contractions that push food through your digestive system.

So if you’re looking to get things moving along, caffeine may give you a little boost. Just be aware that too much of a good thing can backfire. “Caffeine can cause diarrhea by increasing intestinal motility and secretions,” says Rajapaksa. 

“So if you’re already suffering from diarrhea, caffeine can make it worse.” 

The same goes for people with irritable bowel syndrome (IBS), a condition characterized by abdominal pain, bloating, and changes in bowel habits. 

“Caffeine can exacerbate IBS symptoms, so it’s best to avoid it if you have the condition,” she says.

Whatever the reason, there’s no denying that coffee has a powerful effect on our poop patterns. So next time you’re wondering why you have to go so badly after your morning cup of joe, remember that you’re not alone. 


No, coffee doesn’t make everyone poop. Not everyone reacts to things the same, and some people don’t feel the urge to poop after drinking coffee. Nevertheless, it is a common reaction.

So why does coffee make some people poop? Well, coffee is a stimulant. Stimulants can increase bowel movements by stimulating the muscles in your digestive system. This is why coffee is sometimes used as a laxative.

However, not everyone reacts to stimulants in the same way. Some people may find that coffee makes them more alert and awake, but doesn’t affect their bowel movements. Others may find that it has the opposite effect and actually makes them constipated.

There is no one-size-fits-all answer to this question. It depends on the individual and how their body reacts to stimulants. If you’re curious about how coffee will affect you, it’s best to try it out for yourself and see.

So there you have it. Coffee doesn’t make everyone poop, but it is a common reaction. If you’re curious about how coffee will affect you, the best way to find out is to try it for yourself and see.

Why Does Coffee Make You Poop, But Not Energy Drinks? 

Have you ever had an energy drink before? If so, then I’m sure that it isn’t the caffeine in these drinks which makes people have to go. It’s something else! 

So, why does coffee make you poop? Its the compounds found within coffee that stimulate our digestive system and give us the urge to poop as if there were no tomorrow (which might be true). 

Just don’t overdo it on the caffeine – otherwise you’ll end up spending more time at home on the toilet than you wanted- because let’s face facts here: nobody wants their diet cut short by too much pooping…

Is Coffee a Diuretic or Laxative?

For some people, coffee can be a diuretic and a laxative. Regular coffee contains caffeine, which is a diuretic. This means that it can cause you to urinate more frequently. For people who feel the urge to poop after drinking coffee, it acts as a mild laxative. This is because coffee stimulates your digestive system.

Coffee itself may not be the only thing causing your morning trip to the bathroom. If you add cream and sugar to your coffee, this can also contribute to diarrhea. So if you’re trying to avoid making multiple trips to the bathroom, you may want to stick to black coffee.

Is Pooping After Coffee Ok?

Pooping after coffee can be good or bad, depending on your body and your circumstances. There are times when a post-java bowel movement can be positive, and other times when it’s not good or even dangerous.

Pooping after drinking coffee is good when:

  • You need help maintaining regularity: Drinking coffee can help you make sure you’re making a bowel movement every day.
  • You need to go before a big event: Coffee can help you make sure you go before running that marathon, preventing any pit stops.

Thankfully, pooping after coffee can often be a good thing. 

However, there are some situations where it may not be such a great idea. These include:

  • You have diarrhea: Coffee can make diarrhea worse. If you already have loose stools, you may want to avoid coffee or at least go easy on the java.
  • You’re pregnant: Caffeine isn’t good for you or your baby, so it’s best to limit your intake if you’re expecting.
  • You have IBS (Irritable Bowel Syndrome): Coffee can trigger symptoms in people with irritable bowel syndrome. If you have IBS, you may want to avoid coffee or at least drink it in moderation.

So, there you have it. Pooping after coffee can be good or bad, depending on your body and your circumstances. Just use your best judgment and listen to your body!

What Kind of Coffee Makes You Poop?

If you’re the type of person who has a strong reaction to coffee, you might want to be careful about what kind of coffee you drink.

Some coffees are more likely to cause motility in the colon or rectum, which can make the reaction stronger. Warm and highly acidic coffees can amplify the effects.

So if you’re looking to avoid an unpleasant surprise, it might be best to stick with a milder brew. Or, at least, be prepared for a quick trip to the bathroom after your coffee break.

Coffee With Less Poop Problems

If your morning cup of coffee gives you the runs, you’re not alone. In fact, it’s a pretty common problem. But luckily, there are ways to enjoy your coffee without having to deal with an inconvenient (and embarrassing) trip to the bathroom.

One way to avoid coffee-induced diarrhea is to choose a coffee that has a lower acidity level. The acidity of coffee can vary depending on how it’s made, but some methods result in a less acidic cup of joe. 

Low acid coffee is easier on your stomach (and your bowels), so it’s less likely to cause problems.

My choice for the best 3 mild brew/low acid coffees (Yes Im a pooper) are;

1. Eight O’Clock Original Whole Bean Coffee

2. Folgers Classic Roast Whole Bean Coffee

3. Café Bustelo Espresso Style Whole Bean Coffee

Another option is to drink cold brew coffee. This type of coffee is made by steeping grounds in cold water for an extended period of time. 

The result is a smooth, low acid coffee that many people enjoy. And since it’s served cold, it’s even less likely to upset your stomach.

I personally use the NitroTap for this and can recommend it highly!

So if you’re tired of dealing with coffee-induced diarrhea, try one of these options next time you need a fix. Your stomach (and your bathroom trips) will thank you.

Why Does Coffee make You Poop FAQ’s

What Coffee Makes You Poop The Most?

There are a few different types of coffee that tend to make people poop more than others. One is called cathartic coffee, which is made with a higher concentration of coffee beans.

This type of coffee is typically very strong and can have an laxative effect on some people.
Another type of coffee that can make you poop more is decaffeinated coffee. While it doesn’t have the same stimulating effect as caffeinated coffee, it still contains some caffeine as well as other chemicals that can act as laxatives.

Finally, certain brands of instant coffee also seem to have a stronger effect on some people’s digestion, causing them to need to go more often.

So if you’re looking for a coffee that will make you poop more, you might want to try one of these types. Just be sure to start with a small cup and see how your body reacts before drinking too much.

And if you’re really looking to give yourself a boost, try adding a scoop of coffee grounds to your next bowel movement. This will help stimulate your digestive system and get things moving along.

Is It The Caffeiene or The Coffee That Makes You Poop?

Coffee is a popular beverage enjoyed by millions of people around the world every day. For many, it is an essential part of their morning routine. But what many coffee drinkers don’t realize is that their beloved beverage can have some unexpected side effects – like making them poop.

So, why does coffee make you poop? Well, there are two possible explanations. The first is that coffee contains a moderate amount of caffeine. Caffeine is a stimulant that can speed up gastrointestinal motility – meaning it can help to move things along in your digestive system and make you poop.

The second explanation is that coffee itself has a laxative effect on the body. This is because coffee beans contain compounds called chlorogenic acids, which have been shown to stimulate bowel movements.

So, if you’re wondering why coffee makes you poop, it’s likely because of a combination of the caffeine and the laxative effect of the coffee beans.

However, it’s important to note that everyone reacts differently to coffee. Some people may find that it doesn’t have any effect on their digestive system, while others may find that it makes them poop more frequently.

If you’re concerned about the impact coffee is having on your digestion, talk to your doctor or a registered dietitian for more advice.

Is Pooping After Coffee Normal?

It’s normal to poop after coffee because coffee is a laxative. Coffee stimulates the digestive system and causes contractions in the intestines, which helps to move stool along.
For some people, this can lead to more frequent bowel movements or diarrhea.
If you’re experiencing these symptoms, it’s important to stay hydrated by drinking plenty of fluids. You should also avoid caffeinated beverages if you’re trying to reduce your risk of diarrhea.


So there you have it. The next time you’re feeling the urge to poop after drinking coffee, you now know that it’s totally normal and not at all indicative of a flaw in your character. In fact, you can take pride in knowing that you share this little quirk with millions of other coffee drinkers around the world. Are you one of them? Let us know in the comments!
