What In Coffee Makes You Poop? (Question)

Coffee contains a variety of compounds that may stimulate your bowels. These include caffeine, chlorogenic acids and N-alkanoyl-5-hydroxytryptamides. Adding milk or cream may further increase this effect, especially if you’re lactose intolerant.


Why does coffee make me poop right away?

Coffee makes you poop during the day because it affects your digestive system so quickly. When you drink a cup of coffee, it stimulates your body to release the hormones gastrin and cholecystokinin. Both gastrin and cholecystokinin trigger the gastrocolic reflex, which stimulates your body to make a bowel movement.

What type of coffee makes you poop?

And studies have found that decaf coffee (which some people drink for some reason, I guess) can have a laxative effect, too. Scientists have observed — by way of some very invasive studies — that coffee of any sort can stimulate the distal colon, which helps push waste out of the body more quickly.

Does coffee have a laxative effect?

While coffee may have a laxative effect in some people, whether it’s the coffee or the caffeine is unclear. And caffeine within coffee can act as a stimulant, which might induce bile production that increases bowel movements.

How Quickly Does coffee make you poop?

If you’re trying to use coffee to make yourself poop, such as before a race, when should you drink it? It can be as quick as 10 minutes, but for most people, the peak concentration in the blood occurs after 45 minutes.

How do I stop pooping when I drink coffee?

People who regularly consume caffeine may experience mild constipation after reducing their caffeine intake. People can prevent constipation by eating fiber-rich foods and staying hydrated.

Should I stop drinking coffee if it gives me diarrhea?

Caffeine-containing drinks have a laxative potential. More than two or three cups of coffee or tea daily can often cause diarrhea. Withdraw gradually over the course of a few days to avoid headache and try going without for awhile. Decaffeinated drinks may still contain chemicals that can loosen the stools.

Is coffee good for your colon?

As reported in Cancer Epidemiology, Um and her colleagues found that people who drank 2 or more cups of decaffeinated coffee a day had a lower risk of colon and rectal cancer, compared to people who didn’t drink decaffeinated coffee.

How do I completely empty my bowels?

How to empty your bowels without straining

  1. keep your back straight, lean forward.
  2. rest your forearms on your knees.
  3. have knees higher than hips by lifting heels or using a footstool keep your legs apart.

Why Does coffee make you fart?

This may surprise you, but coffee can indeed cause gas. When you drink it on an empty stomach, and it reduces the hydrochloric acid, your stomach may have trouble breaking down protein. All that undigested protein starts eating all the gut bacteria that produce hydrogen sulfide. The result is, well, a gassy stomach.

Is coffee a diuretic or laxative?

For most people, the caffeine in coffee is simply a mild diuretic, which makes the body excrete more liquid. (Think: Pee more often.) But some people are especially sensitive, so they’ll experience more of a laxative effect.

What is a natural laxative?

Prunes. Prunes are probably one of the most well-known natural laxatives. They provide lots of fiber, with 7.7 grams in a 1-cup (248-gram) serving. They also contain a type of sugar alcohol known as sorbitol ( 34 ). Sorbitol acts as a laxative when consumed in large amounts ( 35 ).

Why Does Coffee Make You Poop? (Plus, How To Stop It!)

Many coffee consumers are surprised to discover that their morning cup of joe has an unexpected side effect: it causes them to defecate. (No, you are not the only one.) Coffee does not have this effect on everyone, but it does have a laxative impact on some people. Why does coffee make you poop is a subject that many caffeine consumers have asked themselves. It turns out that there is a physiological explanation why some individuals get constipation after drinking coffee. The chemical composition of coffee can have an effect on gastrin, a hormone that activates the colon muscles.

There are a variety of different reasons why coffee causes you to defecate.

Others, on the other hand, are more sensitive to the acidity of their coffee.

The Science Behind CoffeePoop

Those of you who have experienced the frantic rush to the toilet after drinking coffee may have pondered why this occurs. Because coffee can contain a significant amount of caffeine, depending on how the coffee beans are roasted, many people believe that drinking it will make them defecate. Surprisingly, caffeine is not the cause of the problem. If drinking coffee causes your bowels to move, you aren’t only experiencing the effects of caffeine. Regardless matter how much caffeine is in your coffee, it can make you defecate.

Coffee includes thousands of different components, but none of them have been proven to be responsible for the need to urinate after drinking coffee.

It’s possible that coffee isn’t the only thing that’s making you go to the restroom first thing in the morning.

  • Heat, acidity, certain medical conditions, artificial sweeteners, milk or creamer are all potential problems.

Milk Or Creamer

If you have lactose sensitivity, your latte or creamer may be the source of your frequent toilet visits. It’s possible to be lactose intolerant if your body does not create the enzymes necessary to break down lactose, a sugar found in milk, which causes you to feel nauseous after drinking it. A high-lactose dairy product can result in a variety of unpleasant symptoms, including gas, bloating, flatulence, stomach discomfort, and — yes — diarrhea if consumed in large quantities. So it’s possible that the milk or creamer, rather than the coffee, is the source of your frequent restroom stops.

Hormonal Fluctuations

Scientific research has shown some of the mechanisms by which drinking coffee affects the digestive tract. Coffee causes your body to produce hormones that act throughout the digestive system, including the stomach and small intestine, within minutes of consuming it. It is because coffee affects your digestive system so swiftly that it causes you to defecate throughout the daytime. It is believed that drinking coffee induces the release of the hormones gastrin and cholecystokinin in the body.

These hormones also have the additional effect of increasing the motility (peristalsis) of the colon and rectum.

What happens to your intestines when you drink coffee? Coffee increases the motility of your intestines, which may cause you to need to go to the bathroom more frequently. When it comes to the small intestine, coffee has a minor effect, but it has a significant effect on the colon and the rectum.


Drinking a warm beverage might help to move things along in your digestive tract. Even sipping warm water has been found to increase motility in the bowels, according to research. Drinking hot coffee will undoubtedly assist you in getting out of bed if you need to. The effects of coffee are not entirely explained by the temperature. People who feel the need to defecate after drinking coffee may not feel the same need after drinking another warm beverage, such as tea, since the temperature of the beverage is different.


The majority of coffee is quite acidic, which might cause gastrointestinal irritation. Drinking coffee increases the formation of gastric acid (also known as stomach acid), however decaffeinated coffee has a less noticeable impact. Too much gastric acid might cause issues later on in the digestion process if it is produced in excess. It is possible that food will not be properly broken down and absorbed, resulting in diarrhea.

Health Conditions

Some medical illnesses, such as irritable bowel syndrome, might cause the intestines to empty more often than usual (IBS). In other cases, patients believe they suddenly need to go to the bathroom because they’ve just had a couple cups of coffee, but in reality they’re suffering the symptoms of IBS.

Artificial Sweeteners

Some artificial sweeteners can cause digestive upset and cause things to move around in your stomach. In addition to bloating and flatulence, sugar alcohols such as xylitol, mannitol, sorbitol, and erythritol (found in stevia) can cause other digestive issues such as gas and indigestion. Putting artificial sweeteners containing sugar alcohols in your coffee may actually be causing you to have the urge to go rather than the coffee itself. The question is, why does coffee make you poop, but energy drinks do not?

  1. Coffee contains compounds that stimulate the digestive system in a variety of ways, causing you to feel the need to go.
  2. For some people, coffee can act as a diuretic as well as a laxative.
  3. Coffee can also be used as a mild laxative in the case of people who feel the need to poop immediately after drinking it.
  4. (This is why it has been known to cause explosive diarrhea in some people.) It’s not all in your head, believe me!

Does Coffee Make Everyone Poop?

No, drinking coffee does not cause everyone to defecate. Not everyone reacts to coffee in the same way, and some individuals do not feel the need to go to the bathroom after drinking coffee. Despite this, it is a frequent reaction to the situation.

Is it usual to defecate after drinking coffee? Pooping after a cup of coffee is a common occurrence for many individuals. In fact, after drinking a cup of coffee, 29 percent of people (and a whopping 63 percent of women) experience the desire to urinate immediately.

Is Pooping After Coffee Good Or Bad?

Pooping after coffee may be either beneficial or detrimental, depending on your body and the situation. There are instances when a post-coffee bowel movement can be beneficial, and there are other situations when it is not beneficial or even harmful. When you poop after drinking coffee, it’s a positive sign because:

  • You require assistance in keeping regularity—drinking coffee can assist you in ensuring that you have a bowel movement every day
  • And A cup of coffee can help you start things going without the need to resort to a stool softener or a harsh pharmaceutical laxative
  • If you’re constipated, a cup of tea can assist as well. Coffee can assist you in making sure you go before a large event—for example, before running a marathon, coffee can assist you in avoiding pit stops.

Fortunately, pooping after a cup of coffee is frequently a positive experience. There are, however, some scenarios in which a coffee-induced toilet stop is not the best option. When the following situations occur, drinking coffee can make you poop:

  • You suffer from significant digestive issues such as IBS, which are already interfering with your bowel motions
  • You anticipate that coffee will assist you in pooping, but your body does not respond well to coffee

If you come to rely on coffee to make you defecate, this might be detrimental to your health. Perhaps you should increase the amount of fiber and water you consume in your diet at this time.

Are Certain Coffees Worse Than Others?

Any coffee that increases the motility of the colon or rectum will amplify the reaction to the caffeine. Warm, extremely acidic coffee, in particular, can magnify the effects of the coffee itself by acting as an amplifier. As previously noted, coffees containing milk, creamer, or other additions may need a trip to the restroom. Drinking warm, acidic coffee will increase your want to go to the bathroom even more. It is also possible that the need may strike you more quickly, or that you will have less time between drinking your cup of coffee and having to go.

Coffee For Fewer Poop Problems

Fortunately, you have the option of selecting a coffee that is less likely to cause you to have a sudden and overpowering desire to go to the toilet. For those who find that coffee makes them urinate frequently, selecting the right coffee is critical in order to minimize discomfort. Look for coffee that is gentle on your digestive system when you’re shopping. Keep in mind that coffee transmits a variety of signals to your digestive tract. It changes the hormone levels in your body, which tells your colon that it’s time to move.

  1. Coffee provided at a lower temperature may not cause the same poop difficulties as coffee served at a higher temperature.
  2. Despite the fact that acidity fluctuates from cup to cup, some coffee is produced in a way that decreases acidity.

Why Does Coffee Make Me Poop?

The New York Times’ Aileen Son contributed to this report. A cup of coffee, like opening the shades and stepping into the shower, gets people up and going in the morning — and it does so in more ways than one. In addition to revving up energy levels thanks to the addition of caffeine, many people report that this tasty brew also swiftly and consistently jump-starts gastrointestinal activity and an urgent need to go to the bathroom. It’s astonishing, considering coffee’s widespread use and popularity, that we know so little about how it affects the gastrointestinal tract, according to Dr.

  • Some research on the subject — which tend to be small, old, and limited in scope — have revealed that caffeine is not the primary factor in triggering the need to urinate.
  • And figuring out how they impact the intestines is a difficult endeavor.
  • 92 young individuals were asked to complete out a questionnaire regarding how drinking coffee affected their bowel movements.
  • However, Dr.
  • We also know that a visceral reaction to coffee can occur in a matter of seconds.
  • The investigation revealed a considerable rise in pressure within four minutes of drinking coffee among individuals who stated that coffee generally promoted a bowel movement, but the so-called nonresponders exhibited no change in colon activity after drinking the beverage.

Martindale believes that the fact that consuming a cup of coffee may activate the other end of the gastrointestinal tract within minutes indicates that “it is most likely passing through the gut-brain axis.” This means that when entering the stomach, coffee sends a signal to the brain, which then “stimulates the colon, telling it that we should clear out because things are coming downstream,” as he said.

  1. The coffee, on the other hand, would move much more slowly through the intestines, taking at least an hour to travel the long trip from the stomach to the small intestine and into the colon.
  2. However, coffee appears to have a disproportionately large impact; one research published in 1998 indicated that eight ounces of coffee generated colonic contractions comparable to those induced by a 1,000-calorie lunch.

  4. When bowel function is impaired following abdominal surgery, for example, bloating, discomfort, and an inability to pass gas or tolerate meals are all frequent side effects to experience.

Angelone advises constipation sufferers to consume more fiber-rich fruits and vegetables and to increase their hydration intake and physical exercise in order to alleviate the condition.

A modest amount of fiber may be found in brewed coffee, around one gram per eight-ounce cup.

Angelone said in her article, some people report that coffee produces an upset stomach and loose feces.

According to the Food and Drug Administration, drinking 400 mg of caffeine per day — the equivalent of four or five cups of coffee — is considered safe for the majority of individuals in most situations.

A Doctor Explains Why Coffee Makes You Poop

Doctor Sameer Islam, MD, a gastroenterologist in Texas who specializes in the detection and treatment of illnesses of the gastrointestinal system, has launched a new column, Ask the Poop Doctor, to answer readers’ questions about their bowel movements. On his YouTube channel, he also offers parts such asPoop Tip Thursday andLet’s Talk About Poop, among others. Check out his part on the subject of coffee and your guthere, which is fully dedicated to it. Do you have a question you’d like to ask?

Fill in the blanks in the comments box below!

Why exactly does coffee make you poop?

We are truly baffled as to why coffee causes you to defecate, which is rather amazing. Knowing that coffee causes what is known as the ” gastrocolic reflex”—when your stomach “wakes up” as a result of the coffee and begins to contract—is a good thing. This process continues all the way down your digestive tract, from your stomach to your small intestine to your colon, where you will finally produce a bowel movement. Men and women are both affected by the same phenomenon. Coffee’s acidity is regarded to be one of the factors that contributes to its ability to stimulate the intestines.

The increase in overall acidity causes the stomach to empty its contents more quickly than it would otherwise.

Finally, we now understand that the actual beans and oils in coffee have a part in assisting you in pooping.

Will decaf coffee achieve the same effect?

You will defecate whether you drink decaf or caffeinated coffee, but the caffeine in coffee will encourage you to poop more frequently. So, if you’re really wanting to start a revolution, go for a caffeinated cup of Joe instead of a tea.

Does it matter if you add milk or cream to your coffee?

Yes, all of that milk and cream has the potential to counteract some of the beneficial benefits of coffee. Not to mention the additional calories and sugar that come with using that ingredient.

What about other drinks that contain high amounts of caffeine, such as energy drinks?

The coffee beans themselves and the oils contained inside them include something that permits you to pass gas when you drink them, and this is what we’re talking about. Other caffeinated beverages, such as tea and soda, often do not have the same stimulating impact as coffee.

Have there been any noteworthy studies that help explain this connection?

The closest thing we have is a research conducted in 2018 on patients who drink coffee after surgery, which is the closest thing we have. After surgery, it is common for the bowels to be reluctant to “wake up” (referred to as an ileus). This might result in discomfort, nausea, and constipation. According to the findings of this study, drinking coffee after surgery did help to enhance bowel movement quality.

What’s the connection between coffee, hormones, and gut health?

There is now ongoing study being conducted to determine whether or not coffee can help your overall gut health. Coffee has been found to enhance liver health, lower the risk of colon cancer, increase cognitive function, and lower the risk of cardiovascular mortality (CHF, heart attack, stroke), type II diabetes, Parkinson’s disease, and other diseases and conditions.

Keep an eye out for further research that will be released in the near future.

How do conditions like IBS and lactose intolerance factor in?

Patients with IBS may find that drinking coffee has little effect on their symptoms, particularly if they have IBS that is constipation-predominant. However, if you’re dealing with digestive disorders such as diarrhea or GERD and heartburn or have lactose intolerance, drinking coffee may make your symptoms worse. The way each person responds to a situation is unique.

If you’retryingto use coffee to make yourself poop, such as before a race, when should you drink it?

It can take as little as 10 minutes, but for the majority of people, the peak concentration in the blood takes 45 minutes or more to reach its maximum level. To avoid having to pee immediately after drinking it, plan ahead of time if you’re taking a lengthy trip or competing in a race.

How much coffee do you need to achieve the, um, desired effect?

The effects of coffee are distinct for each individual, as is the way they react to it. There are a variety of elements to consider, including your tolerance to caffeine, whether you have any other medical concerns (such as IBS or heartburn), the type of coffee you consume, and so on and so forth. Most healthy individuals, on the other hand, appear to be able to tolerate up to 400 milligrams (mg) of caffeine per day. Approximately the amount of caffeine found in four cups of freshly ground coffee, 10 cans of cola, or two “energy shot” beverages (depending on how you measure it).

Why does coffee make you poop?

For those of you who are like me, a cup of coffee is a must-have to get you through the day. However, if you’re anything like me, you’ll be seated on a porcelain throne, doing your first poop of the day approximately 20 minutes after that first cup of coffee has been finished. Coffee has the effect of making you poop. Isn’t that a proven fact? Obviously, since you can buy t-shirts and mugs with that wording on them, and mugs never lie. Are our bowel movements being triggered by the coffee, or is it something else entirely?

  1. This notion, on the other hand, is easily checked.
  2. To be more specific, the researchers utilized a manometer (a device that detects pressure) to monitor the colon’s activity since there is a pressure change when a portion of the digestive system contracts in order to push food toward the anus.
  3. Decaf coffee stimulated colonic activity more than water, and only slightly less than caffeinated coffee did the same thing.
  4. An investigation published in 1999 concluded that “caffeine cannot be held primarily responsible for these gastrointestinal symptoms.” According to a study conducted in 2008, caffeine does, in fact, have a function in weight loss.
  5. The researchers discovered that drinking coffee resulted in greater anal sphincter spasms as well as an increased need to defecate afterward.
  6. It’s possible that coffee’s interaction with stomach acid is responsible.

A number of different things are triggered by Gastrin, including the release of more hydrochloric acid and digestive enzymes, an increase in stomach contractions, the relaxation of the valve between your small and large intestines, and the relaxation of the sphincter between your stomach and small intestine.

  • As a result, if coffee promotes gastrin, and gastrin stimulates digestion, it is possible that this route represents a method by which coffee causes us to defecate.
  • This response is initiated by the stomach extending when you eat or drink anything, and it stimulates the colon to contract, increasing the motility of the colon.
  • Several distinct chemicals, including gastrin, are involved in the regulation of this response.
  • Interestingly, this reflex is more active in the mornings, which might explain why a cup of coffee at 9 a.m.
  • When researchers looked into the link between bowel activity and circadian rhythms, they discovered that colonic activity is significantly lower at night and in the evenings, but that it increases immediately after waking up.
  • In any case, it appears that coffee isn’t the only thing that makes us want to go to the bathroom before midday.
  • In a 1990 survey of 99 participants, it was discovered that coffee only prompted an urge to defecate in 29 percent of those who took part.
  • Consuming coffee (regular or decaf) resulted in enhanced colon motility in those eight participants, but not in the other six.
  • The interactions between coffee and the colon, like other physiological impacts, are complicated and numerous, and we still don’t completely understand how they work.

Personally, I’m OK with simply acknowledging that my daily cup of coffee contributes to my ability to maintain a regular schedule, in whatever way it is able to do so. @AdaMcVean Please leave a remark!

So THIS is Why Coffee Always Makes You Poop

Doctors of gastroenterology explain why you must always go to the restroom after your morning cup of coffee. Everyone has experienced it at some point: you drink down your morning cup of coffee and, within minutes, you’re sprinting to the bathroom—and not just for a fast pee. Whether you like it or not, coffee poop is a fact of life, and while they’re certainly not the most interesting topic of discussion, you have to admit: they’re there. You’re wondering as to why drinking coffee makes you feel the need to defecate right away.

  • We don’t know what’s causing it yet, and there have only been a handful of studies that have looked into it,” says Kyle Staller, M.D., a gastroenterologist at Boston’s Massachusetts General Hospital.
  • Dr.
  • The fact that people who drink their favorite beverage don’t have the same degree of colonic movement afterward is not entirely surprising, according to Dr.
  • The warmth of the coffee (you don’t have the same impulse to go after drinking tea or soup, according to Dr.
  • Ashley Farhadi, M.D., a gastroenterologist at MemorialCare Orange Coast Medical Center and head of MemorialCare Medical Group’s Digestive Disease Project in Fountain Valley, California, notes that the acidity of coffee is similar to that of citrus fruits.

So then whydoescoffee always make you have to poop?

According to Dr. Staller, there appears to be something in coffee as a whole that swiftly triggers receptors in your gastrointestinal system, causing your stomach and colon to constrict. (I understand that this is a less-than-satisfying response.) According to the United States National Library of Medicine, those contractions occur in your body after you eat as part of a process known as peristalsis, which is a series of wave-like muscle contractions that transport food to different processing stations in the digestive system.

As Dr.

On the other hand, if you suffer from constipation, having a coffee habit may really be beneficial.

Staller recommends that patients take their prescription first thing in the morning with their food and coffee.

“A bowel movement is most likely to occur when you first wake up (since your colon is waking up), after eating a meal, and after drinking coffee. It provides you the best chance of getting things going if you sync those three elements together.”

Okay, but is there any way tostoppooping whenever you drink coffee?

Dr. Farhadi clarifies that this is not the case. As food stimulates your colon, it’s doubtful that drinking coffee with a meal will make a significant impact, if any, in your colon health. According to Dr. Staller, the same appears to be true when diluting coffee with other liquids, such as milk in a latte. If the whole pooping after coffee thing is really getting to you, you may try to discover your limit by cutting back on the coffee until you reach a point where you don’t have to run to the bathroom every time you drink a cup of coffee.

Farhadi adds of treatment.

Farhadi, on the other hand, proposes that you see your timely coffee poops as a positive development.

“That’s a significant advantage to drinking coffee,” says the author.

Coffee Makes You Poop

A considerable number of people experience the need to defecate after drinking coffee, which is one of the many impacts of the beverage. There is a chance that this will be a welcoming reaction. Despite the fact that the coffee bean is essentially the seed of the coffee fruit, it contains properties that are similar to those of other types of beans. Some people find that drinking coffee causes them to feel the need to go to the restroom right away. Others report that it causes them to have a bowel movement in a more modest way.

Who Feels the Laxative Effects of Coffee?

According to a famous research on the subject, coffee causes around 29 percent of the population to require a bowel movement shortly after consuming it. Women were far more likely than males to report the impact, with 53 percent of the women in the research reporting it compared to only 19 percent of the men. However, this was a small-scale investigation.

When Do You Need to Poop?

Coffee, according to the study, only causes people to have a bowel movement in the morning for 52 percent of those who participated. Similarly, 58 percent of those polled indicated that coffee had this impact only if they hadn’t defecated earlier in the day. Those who were “moved” by coffee said that there was a time lapse of around 20 minutes between drinking coffee and going to the bathroom. Measurements were taken in a 2005 research, which revealed that coffee induced a response in the colon within 30 minutes of consumption.

Why Does Coffee Make You Poop?

The distal colon, which is positioned at the end of the colon and is the most well-documented reason for people defecating after drinking coffee has to do with a response in the colon. It is not completely understood why this is the case, but scientists believe it is due to the hormonal effects of the exorphins in coffee (which bind to opiate receptors in the gut and either slow down or speed up your digestion), as well as the presence of two naturally occurring chemicals in coffee called gastrin and cholecystokinin.

They have the potential to activate muscular spasms in the lower colon, resulting in increased bowel movements in the 20 minutes following coffee consumption.

Some believe that the caffeine is to blame, however studies have shown that decafcoffee is just as likely as normal coffee to induce people to have a bowel movement.

People who are sensitive to artificial sweeteners, cream, or milk in their coffee may have defecation as a result of drinking it.

Some people suffer from lactose intolerance, which manifests itself as symptoms such as loose stools after consuming dairy products. Some artificial sweeteners contain alcohol sugars such as mannitol, sorbitol, xylitol, and maltitol, which have a laxative effect and can induce diarrhea.

Coffee does make you poop, but it’s not because of caffeine

Kailey Proctor, MPH, RDN, CSO, a board-certified oncology dietitian at the Leonard Clinical Cancer Institute in partnership with Mission Hospital, provided medical review for this article.

  • Coffee has been shown to encourage bowel motions, however experts are unaware of the specific reason behind this. Since decaf coffee can have the same impact as regular coffee, it is not the caffeine that causes some individuals to defecate. Four cups of coffee is the maximum amount of coffee that should be consumed in a day, according to the experts. More information may be found in Insider’s Health Reference collection.

For many individuals, the day doesn’t begin until they’ve had their first cup of coffee. However, this morning ritual is frequently followed by a trip to the restroom. In a tiny 1990 research, 29 percent of individuals had a bowel movement as a result of drinking coffee. However, there is no conclusive explanation as to what it is about coffee that has a laxative impact on the stomach. The majority of individuals believe that caffeine is to blame. Despite the fact that caffeine has been demonstrated to promote an earlier need to defecate and is a recognized stimulant, decaffeinated coffee has been shown to accelerate bowel movements.

Jill Deutsch, head of the Yale Functional Gastrointestinal Disorders Program.

Why does coffee make you poop?

Even though the specific cause of coffee’s laxative action is unknown, experts believe that it is a mix of several elements. “The short answer is that we aren’t really certain! It appears that the general composition of coffee is responsible for our ability to defecate “Deutsch expresses himself. The amount of coffee required to trigger a bowel movement is not standardized since the amount required varies from person to person. “Drinking coffee does not provide the same laxative benefits to everyone who consumes it.

Is it healthy to drink coffee as a laxative?

According to Deutsch, if drinking coffee as a laxative works for you, it may be beneficial to your health. It is safe to consume up to 400 milligrams of caffeine per day without experiencing any negative side effects, which is approximately the amount found in four cups of coffee. However, long-term ingestion of large dosages of caffeine may result in dependence on the stimulant. In addition to coffee, other beverages such as sodas, teas (including kombucha), and energy drinks contain caffeine.

As Deutsch points out, “we don’t have any evidence to suggest that other caffeinated beverages are associated with more bowel movements.”

Insider’s takeaway

Some people report that both caffeinated and decaffeinated coffee help them to pass more stool, although there is no scientific evidence to support this claim. There is a possibility that the general digestive effects of coffee and milk, as well as the time you consume it, all contribute to the laxative impact. If it works for you, drinking coffee as a laxative might be beneficial. However, using more than 400 mg of caffeine in a day (approximately four cups of coffee) on a consistent basis may result in caffeine dependence.

Here’s why coffee makes you poop

So, yes, that’s all. After consuming their morning cup of coffee, around 30% of individuals feel the desire to defecate. If you’re one of the three lucky ones out of ten, you’ve undoubtedly wondered what the deal is with all of this. As tempting as it is to credit the impact to caffeine, which is the component you’re looking for when you slurp down a cup of coffee, this is not the case. But consider this: soda does not have the same impact as coffee. As well as decaf coffee (which some people drink for some reason, I think), studies have discovered that regular coffee can have a laxative effect.

As a result, the physical process is well recognized, but what causes it is not.

Coffee contains a chemical known as chlorogenic acid, which causes greater stomach acid levels as well as increased production of gastric acid in the stomach.

In addition, something in coffee may cause the production of hormones that help digestion, which would result in more frequent bowel movements.

Numerous people feel that drinking coffee causes them to defecate, and some physicians may advise patients who suffer from certain digestive disorders to avoid drinking coffee altogether. Despite this, studies have yet to find evidence to support the claim that coffee causes you to urinate. Despite the fact that some people claim that coffee causes them to defecate, others do not report having the same sensation. In this post, we will look at the reasons why some individuals experience feces after drinking coffee.

  • Despite the fact that studies are divided on the subject, many individuals assume that coffee causes them to poop.
  • At the same time, many persons who suffer from irritable bowel syndrome (IBS) believe that drinking coffee exacerbates their digestive symptoms.
  • Some research have found that coffee has a laxative effect, however other investigations have found that it does not.
  • The findings of each of these investigations are discussed in further detail in the following sections.

According to some research, coffee may stimulate several organs of the gastrointestinal tract, including the stomach, gallbladder, and colon. Researchers have attempted to corroborate these effects, but other research suggests that coffee may not have an influence on bowel motions at all.

1. Gut stimulation

An previous research conducted in 1998 discovered that caffeinated coffee, decaffeinated coffee, and a 1,000 kilocalorie (kcal) meal generated greater contractions in the colon than simply drinking water. Caffeinated coffee stimulated colonic movements 60 percent more strongly than water, while decaffeinated coffee stimulated colonic movements 23 percent more strongly than water, according to the findings. An 800-calorie breakfast had the same effect as consuming caffeinated coffee, according to the study.

According to the findings of another study with six individuals, drinking coffee after a meal may aid in the stomach’s ability to empty more rapidly.

The World Journal of Gastroenterology published a review that concluded that caffeinated coffee may enhance acid production in the stomach as well as movement in the colon in certain individuals.

It was discovered that coffee increased the strength of contractions in the anus and rectus muscles.

2. Hormones

Coffee may also cause the production of a hormone known as cholecystokinin from the colon, which is beneficial. Cholecystokinin has been demonstrated to be a stimulant of bowel motions, according to research. It is still unknown whatever component of coffee causes the release of this hormone to be stimulated in the first place.

3. Worsening IBS symptoms

Many patients who suffer from IBS claim that particular foods trigger their symptoms, and others have reported experiencing diarrhea after drinking coffee. In a 2016 study, researchers came to the conclusion that coffee was a trigger for IBS symptoms in certain patients, and that it might make their symptoms worse. The researchers, on the other hand, were unable to pinpoint the components of coffee that are responsible for these symptoms. One study conducted in 2015 looked into how persons suffering from inflammatory bowel disease (IBD) assessed the impact of coffee on their symptoms.

Sixty-two percent of individuals who do not drink coffee feel that coffee makes their digestive problems worse, according to the survey.

4. Milk and cream

After infancy, over 65 percent of the world’s population has difficulty digesting lactose completely. Lactose is a sugar that may be found in milk and other dairy products. Diarrhea can be caused by lactose intolerance. People who add dairy items to their coffee, such as milk, may have constipation as a result of the lactose that has been added to their beverage. The belief that coffee causes individuals to defecate has yet to be proven correct by researchers. Some people may be more sensitive to coffee than others, and some people may not notice any affects on their stomachs as a result of drinking coffee.

Continued research with bigger sample sizes will be required to determine whether or not coffee has an effect on bowel motions.

Researchers will need to figure out which component of coffee (for example, caffeine) is responsible for the laxative action if they establish that coffee induces bowel motions.


Coffee has been shown to have laxative properties in certain trials, but not all. A short research conducted in 2005 with 16 participants found that there were no variations in the force of contractions in the rectum 45 minutes after the people consumed coffee or water. The findings of another study, which was published in 2018, looked at the elements that determine how long food takes to transit through the digestive tract. In this study, the researchers discovered a link between consuming coffee and food moving more slowly through the stomach.

  1. In a brief research published in the European Journal of Gastroenterology and Hepatology in 1998, it was shown that decaffeinated coffee might help to promote bowel motions.
  2. However, according to the findings of this study, even when producers remove caffeine from coffee, people may still experience the need to urinate after drinking the decaffeinated version of the beverage.
  3. It is necessary to conduct more study to discover what these substances could be.
  4. Some people may be compelled to poop as a result of this, while others may not.

Is Coffee A Laxative?

However, despite the fact that this problem affects 30-40 percent of the population, little research has been done to determine what precisely is causing it to occur. It’s often attributed to coffee, with some stating it stimulates the intestines and makes them more active.

Nonetheless, some argue that more people have feces problems when they drink decaf rather than soda, implying that there is another cause of the problem. So, what precisely is the source of the problem?

Main Suspects

On one side of the debate, the acidity of coffee is being blamed as the source of the problem. Because both drugs have various affects on different people, your problem might be with one or both of these substances, to be completely honest. In order to figure it out, you must first notice what other factors are driving you scurrying to the restroom. Are you going to the bathroom because of the spaghetti sauce and fresh fruits, or are you going to the bathroom because of the dark chocolate and Excedrin?

Caffeine should be avoided if the latter is the case.

Other Possible Culprits

If that wasn’t enough to throw you off your game, just wait. If this is a problem that occurs every morning, it is possible that the problem is not with the coffee at all. The possibility exists that you’re simply triggering your gastrocolic reflex by pouring the drink into an empty stomach without realizing it. Simply put, it’s caused by a hormonal signal to your colon that tells it to “clear out, we’re getting more foodstuffs!” As a result, you’re essentially just making room for more things to digest.

Additionally, because all adults are at least a little lactose intolerant, it’s possible that the milk you use in your coffee is the source of the problem–especially if you use a lot of it.

What Exactly is Happening in There?

Regardless of what exactly is causing the reaction, we do have a general understanding of what is going on with you at this point. Coffee has been demonstrated to activate the distal colon, according to research. This is the section of your digestive system that aids in the more rapid elimination of waste. As a result, peristalsis might be triggered or at the very least encouraged. That is the coordinated contraction and relaxation of intestinal muscles, which is ultimately responsible for the production of stools.

However, at the end of the day, it is the stimulation of these muscles that is causing you to require the use of the bathroom.

Potential Solutions

When it comes to decreasing the acidity of your morning cup of coffee, you actually have a surprising amount of alternatives! If you just want to jump to some low-acid coffee recommendations,go here.

Buy a Low Acid Coffee

On this front you may go for treated or unintentional low acid coffee. The acid content of the treated ones has been reduced by the use of specific processing processes, either before or during roasting. Coffees that are accidentally low in acid are those that are naturally low in acid. Lower altitudes often imply less acidity, which is reflected in the lower acidity of darker roasts to some extent. Beans with low acid content are also naturally produced in several unique sources such as the Brazilian Amazon, the Indonesian island of Sumatra, Peru, Guatemala, and Mexico.

Also, it’s important to remember that arabica beans, in addition to having more complex flavor profiles, are often less acidic than other beans.

How to Brew to Reduce Acidity

Honestly, if you’re wanting to cut the acid,cold brewsare your new best buddy. A slow-steeped cold-brew will be about70 percent less acidicthan your regular, hot drip coffee, even if you’re using the exact same beans. If you really must have your coffee hot, don’t worry. You still have alternatives. When making hot coffee and wanting to prevent high-acid coffee, try to skip the fine grind and opt for something coarser. Basically, aFrench pressneeds to be in your house. You may create hot orcold brewswith it AND it demands a coarse grind.

So if you’re not allergic to dairy, you can use milk to help neutralize the acid in your cup.

Lastly, if none of these methods worked for you, try adding aneggshellto your coffee.

If It’s a Caffeine Problem…

Many people who argue that caffeine is not the cause of the disease because the trials were done using decaf are unaware that decaf contains caffeine as well as regular coffee. While far less caffeine than your regular cup, decaf coffee still includes around 7 mg of caffeine per cup, which implies that approximately 3 percent of the caffeine has been left behind. So, presuming that there isn’t any way to obtain your coffee fix without caffeine to some extent, you have a few of alternatives for minimizing the amount of caffeine you consume.

For those who don’t want to go all the way down to decaf, a half-caff is also an option to consider.

Additionally, increasing your coffee consumption on a daily basis helps you build a resilience to the adverse effects of caffeine.

If It’s a Milk Problem…

This is a simple one. Don’t bother adding milk to your coffee any longer. Most establishments have some form of non-dairy milk substitute, whether it’s coconut, almond, or another type of alternative. Simply request that the dairy items be substituted with the items that will not put you in the oval office within the next hour. Making coffee at home and becoming addicted to the flavor of your creamer? Try using non-dairy milk and a syrup instead of the regular stuff. There are so many possibilities available for additional flavoring that you should be able to discover something that is an acceptable replacement for your current favorite.
