3 Reasons Coffee Upsets Your Stomach (And How To Fix It)
If you find yourself running to the bathroom with the first sip of coffee, you're not alone. Many people have this after drinking coffee. While it wakes you up, it may also get your bowels moving because it can stimulate the digestive tract. But does your morning cup of joe cause coffee diarrhea?
VIDEO OF THE DAY
While the jury is still out on the effects coffee has on digestion, research links coffee with the urge to go. In fact, coffee is so notorious for prompting bathroom trips that some people try coffee cleanses and coffee enemas as a way to clean their colons.
A small study of 34 participants published in the July 14 issue of Clinical Nutrition Research even concludes that coffee enemas may be a way to effectively prepare for a colonoscopy.
Tip
Coffee does not directly cause diarrhea in most people. Instead, it may stimulate the digestive system, although others may react to added dairy products or artificial sweeteners.
What Causes Coffee Diarrhea?
Coffee contains caffeine, a stimulant that can help you stay awake and alert. However, according to a small study of 53 participants published in 2016 in the European Journal of Sports Science, caffeine can also stimulate active contractions in your colon and intestinal muscles.
In addition, coffee is also linked to stimulating hormones that the body uses to activate the colon. A small study of 40 healthy men and women published in March 2016 in the journal Nutrition showed that coffee can activate the sympathetic nervous system, which is responsible for the "fight or flight" response and can directly affect the intestines — and that can cause diarrhea and other GI issues.
Finally, people often add dairy products, which contains lactose, to their daily coffee. According to the U.S. Department of Health & Human Services, about 65 percent of the world population has difficulty digesting lactose. Diarrhea is a common symptom associated with lactose intolerance.

Causes of Morning Diarrhea
At times, diarrhea in the morning can coincide with having a cup of coffee. However, in most cases, the cause of diarrhea is not likely the cup of coffee. A 2017 study in Planta Medica says there is no correlation between coffee and stomach and digestive issues. Coffee may actually protect people from developing some forms of inflammatory bowel disease that can cause diarrhea.
According to the National Institute of Diabetes and Digestive and Kidney Diseases, some of the most common causes of acute diarrhea include viral, bacterial or parasitic infections, and medication side effects. In addition, the Institute identified common causes for chronic diarrhea. Digestive health issues including abdominal surgery and long-term medication use can all cause chronic diarrhea.

Quick Diarrhea Treatment
No matter the cause of the diarrhea, it's fairly easy to alleviate symptoms at home. Simple home remedies and over-the-counter medications can ease discomfort related to diarrhea.
If you are experiencing diarrhea, make sure you stay hydrated. You can lose a lot of water and become dehydrated quickly when you have multiple loose bowel movements. To combat this, drink water, juices and sports drinks to help rehydrate. Avoid drinks that contain caffeine, alcohol or carbonation, which can all irritate your bowels.
Additionally, you should eat a bland diet while you are experiencing or recovering from diarrhea. This typically consists of bananas, rice, bread and applesauce. Avoid heavy foods that contain a lot of grease, artificial sweeteners and fat.

To help alleviate symptoms, you can try an over-the-counter medication, such as those that contain loperamide. However, if you experience dizziness, abdominal pain, bloody diarrhea, signs of dehydration or a high fever, you should not take medication and instead seek immediate medical attention.

Coffee contains chlorogenic acids that speed up digestion and promote the production of stomach acid
First, know that if your morning cup of coffee makes you run to the bathroom, you're not alone. Caffeine, including caffeinated coffee, is actually a laxative. While not nearly as strong as a laxative you'd buy at the drugstore, your morning espresso or latte has the power to make you poop — fast.
Coffee triggers peristalsis — muscle contractions through the gut, helping your body to move things along. Your personal digestive tract determines how your body responds to caffeine. Some people notice the common laxative effect of caffeinated coffee, while others do not.
In addition to caffeine, coffee also contains chlorogenic acids. These acids speed up digestion and promote the production of stomach acid.
Coffee isn't the only thing to blame when it comes to pooping in the morning — the delicious additions you use to make your coffee taste fantastic can also be an issue. Dairy products, creamer, sweeteners (both natural and artificial) can all have a laxative effect on some people.
Sick Of Coffee-Induced-Pooping?
While a cup of joe can be an easy cure for constipation, many people prefer their morning cup of coffee without a trip to the bathroom.
Good news: there are a few things you can do to fix the problem.
First, you may want to consider switching to decaf coffee. If you still prefer a little bit of caffeine, switch to half-caff — a combination of decaf and regular coffee. You may need to play around with the ratio until you find the perfect balance of caffeine buzz and decaf mellow.
Prefer to stick with a standard brew instead of switching to decaffeinated coffee? Try switching to a darker roast. These beans are naturally less acidic and may have less of an effect on your digestive system.

Seek immediate consultation from your doctor if you are regularly having constipation
According to gastroenterologists, it's ok if you use your morning cup of coffee as a way to get your digestive system moving.
If you find that you're regularly constipated, however, it's worth mentioning to your doctor. Many people experience constipation as a result of dehydration. Since the caffeine in coffee acts as a diuretic, your doctor may recommend that you drink less caffeine and more water to keep your digestive system healthy.
Why Does Coffee Make You Poop?
If you find that you need more and more caffeine to poop, keep an eye out for side effects that indicate that your caffeine consumption is too high for your tolerance. If you feel shaky, experience regular stomach upset, or have trouble sleeping at night, it might be time to cut down.
The Final Word On How To Stop Coffee From Making You Poop
You love your morning cup of joe, but hate how it makes you run to the bathroom — we get it. Trying a darker roast, lessening the amount of caffeine in your coffee, and switching up your creamer or sweeteners can all stop the coffee from making you poop.
If coffee just gives your digestive system a small boost, you're in the clear — doctors say that this isn't a bad thing.
FAQs On How To Stop Coffee From Making You Poop
Why Does Coffee Make Me Poop In The Morning?
Coffee contains caffeine, which acts as a mild laxative and makes some people poop. Certain acids in coffee can also cause increase the amount of stomach acid in your body, which may make you poop.
Lastly, coffee additives — like sweeteners, dairy products, and creamer — may also be the root cause of what's making you run to the restroom after your morning cup of coffee.
Is There A Way To Stop Coffee From Making Me Poop?
Try a darker roast, which naturally is less acidic and has less caffeine. You can also try switching to decaffeinated coffee, or you can try a half-caff blend. You may also want to try different additives to your coffee, or try drinking it black.
Diarrhea occurs when a person has loose or watery stools. Many different conditions have diarrhea as a symptom.
Most people experience this common illness at some point in their lives, with short-term cases of diarrhea being the second most commonly reported illness in the United States.
A person with chronic diarrhea will typically experience runny stools for longer than 4 weeks, according to the American College of Gastroenterology.
Acute diarrhea should not be a cause for medical concern. However, chronic diarrhea may cause other problems if a person does not receive treatment for it.
In this article, we discuss chronic diarrhea, its causes, and the available treatment options.
Causes
There are many potential causes of chronic diarrhea. Some of the most common include:
Excessive alcohol or caffeine intake
Drinking large amounts of alcohol may cause chronic diarrhea.
Drinking large amounts of alcohol or beverages that contain caffeine, such as coffee or cola, can cause loose and watery stools.
When a person stops consuming these substances or starts to consume them in more moderate amounts, the symptoms should resolve.
Sugar and dairy
Certain sugars and artificial sweeteners may cause diarrhea. Consuming these sweet substances every day can even lead to chronic diarrhea.
Examples of such sugars and artificial sweeteners include:
Sorbitol: Manufacturers use this calorie-free sugar substitute in candies, chewing gums, and sugar-free items.
Mannitol: This sweetener can have a laxative effect similar to that of sorbitol.
Fructose: This naturally occurring sugar is present in fruit and honey. Eating large amounts of fruit can cause diarrhea due to its high fructose content. Food producers may also add fructose to candies and sodas.
Lactose: This is a natural sugar in dairy that can cause chronic diarrhea in people whose bodies cannot digest it. Around 65% of people around the world have problems digesting lactose.
Herbs and herbal remedies
Herbal remedies and herbal teas, such as senna, may contain natural laxatives.
If a person is using several herbal products at once, it may be a good idea to stop using them all, then reintroduce them one at a time. This may help the person work out which product is the cause of the chronic diarrhea.
8 Signs You Should Stop Drinking Coffee (If You Get 2 Symptoms You Need a Break)
Medication
Chronic diarrhea can be an adverse effect of several prescription and over-the-counter (OTC) medications.
Some common medications that can cause diarrhea include:
most antibiotics, including cefpodoxime, amoxicillin, and ampicillin
some antidepressants, such as selective serotonin reuptake inhibitors and serotonin-noradrenaline reuptake inhibitors
antacids that contain magnesium hydroxide
laxatives and stool softeners
proton pump inhibitors, including omeprazole and lansoprazole
chemotherapy drugs to treat cancer
Also, diarrhea may signal toxicity from some medications, such as lithium and digoxin.
Infection
In some cases, an intestinal parasite can give rise to chronic diarrhea. This is less common in the U.S. than in countries with less developed food and water sanitation.
A stool test is usually necessary to diagnose a parasitic infection. A doctor may also carry out a biopsy.
Inflammatory bowel disease
Inflammatory bowel disease (IBD) is an umbrella term for several chronic conditions involving inflammation of the gut. Two of the most common are Crohn’s disease and ulcerative colitis.
Some symptoms of IBD include:
blood in the stool
tiredness
fever
nausea
stomach pain and cramps
There is currently no cure for IBD. However, people can usually manage it using medications and by making lifestyle changes.
Other causes
These can include:
Irritable bowel syndrome (IBS): This is a functional disorder that can cause diarrhea, constipation, or both.
Gallbladder removal: Following this procedure, more bile may build up in the colon. This may lead to diarrhea.
Hormonal disorders: Some examples of hormonal disorders include overactive thyroid and diabetes.
Surgery: Diarrhea can be a complication of some types of abdominal or intestinal surgery.
Allergies: In rare cases, food allergies can lead to loose and watery stools.
Rare tumors: For example, carcinoid tumors produce hormones that cause diarrhea.
Symptoms
The American College of Gastroenterology define chronic diarrhea as a symptom that causes loose or watery stools for 4 weeks or longer.
Other symptoms may be present, including:
bloating
more frequent bowel movements
a sense of urgency to pass stool
stomach cramps
nausea
Sometimes, diarrhea can also cause a burning sensation. Learn more about what causes this, plus other symptoms, here.
Complications
The most serious complication of chronic diarrhea is dehydration. This can be life threatening if a person does not receive treatment or rehydrate.
Some signs of dehydration include:
dark urine
dizziness and shakiness
excessive thirst
tiredness
fever
Learn more about dehydration and how to treat it here.
Diagnosis
A doctor will carry out a physical examination to diagnose chronic diarrhea. Follow-up tests can help determine the underlying cause.
During the examination, the doctor will ask about any symptoms the person has experienced, as well as their family medical history. They will primarily focus on any history of digestive problems.
It can also be helpful for the person to disclose what they tend to eat and drink, any medications they are taking, whether or not they drink alcohol or take illicit drugs, and their recent travel history.
Coffee Causing Loose Bowels | Health Tip | Helena Davis
The doctor may then request:
blood tests
a stool sample to test for inflammation, bacteria, or parasites
an ultrasound or CT scan
If blood tests and stool samples do not reveal any reason for the chronic diarrhea, the doctor may order imaging tests to check for problems in the digestive system.
If the cause remains unknown despite these tests, the doctor may diagnose IBS. People with this condition have digestive systems that appear normal but do not function as they should.
Treatment
Treating chronic diarrhea depends on its underlying cause. Some potential treatment options include:
Managing any related conditions
Diarrhea that occurs due to a medical condition, such as IBD, might resolve with treatment of the underlying condition.
It is important to work with a doctor to develop a treatment plan that addresses the diarrhea as well as any underlying illness.
Taking or switching medications
Antidiarrheal medications are a short-term remedy. Although they tend to relieve symptoms, people should not use them on an ongoing basis.
Other medications that may help include:
antibiotics, for bacterial infections that cause diarrhea
codeine-containing medications, which can reduce watery and loose stools
OTC medications to slow down the passage of stool through the digestive tract, including bismuth (Pepto-Bismol) and loperamide (Imodium)
People taking medications that can cause chronic diarrhea should talk to their doctor about alternative drugs that do not have this side effect.
Hydrating
Diarrhea can cause extreme dehydration, especially when it continues over an extended period of time.
As a result, it is important to drink plenty of clear fluids throughout the day. Options include water, noncaffeinated teas, and low sodium broths. This can help people with chronic diarrhea stay hydrated.
Making dietary changes
If a specific dietary item is the cause of the chronic diarrhea, a person can try removing this food or beverage from the diet to see whether or not symptoms improve.
Once the diarrhea symptoms clear up, it may be possible to gradually start eating these foods again on an infrequent basis, or in moderate amounts.
Keeping a food diary can also help people spot trigger foods.
Other dietary changes that may help include:
achieving better portion control
limiting or avoiding caffeine
limiting or avoiding alcohol
Trying natural remedies
Some natural products may help relieve chronic diarrhea. Probiotics, for example, can restore a healthy balance of bacteria in the gut.
Some fiber supplements, such as psyllium, can also relieve chronic diarrhea. They may be especially helpful for those with IBS or other digestive conditions that cause loose stools.
However, people should avoid using psyllium products that also contain laxatives.

Prevention
Not all cases of chronic diarrhea are preventable. However, it is possible to reduce the risk of chronic diarrhea by:
keeping a food diary and seeing how cutting particular foods from the diet affect the diarrhea
discussing the side effects of any current medications with a doctor
requesting a change in medications if necessary
taking probiotic supplements regularly
drinking only clean or filtered water
washing the hands both before and after food preparation
cleaning and thoroughly cooking meat before eating it
washing fresh produce before eating it
cleaning kitchen surfaces regularly
washing the hands regularly, especially after using the bathroom or coming into contact with a person who is ill
When to see a doctor
A person should see a doctor if they have diarrhea that lasts longer than a few days or if other symptoms accompany it, such as fever or fatigue.
If a person notices any symptoms of dehydration, they should consult a doctor immediately.
Outlook
The underlying cause of the chronic diarrhea will determine its treatment options and outlook.
People with food intolerances or those experiencing substance-related diarrhea will usually find relief if they avoid or limit their intake of the substance in question.
For other people, changing medications under the supervision of their doctor will be enough to resolve the symptom.
Antibiotics are usually successful in treating bacterial infections that cause chronic diarrhea.
If a digestive condition or other medical concern causes loose or watery stools, symptoms should gradually resolve once the person has received treatment for it.
The most important step for recovery is to consult a doctor.
Q:
Does Clostridium difficile cause chronic diarrhea?
A:
If left untreated, C. difficile can cause chronic diarrhea. C. difficile, when laboratory testing confirms its presence, always requires treatment, especially if it is causing diarrhea.
However, even with proper treatment, up to 20% of people can get sick again. This is either because the initial infection never completely resolved or because there was a reinfection with a new strain of C. difficile bacteria.
Reinfection can happen multiple times in some people, even when treated appropriately each time.

Why do I get diarrhea after drinking coffee in the morning?
Morning diarrhea is when a person passes a loose, watery stool first thing in the morning. The need to go to the bathroom may wake someone with morning diarrhea up. They may also feel they need to go urgently when they first get up.
Most people experience morning diarrhea at some point. Occasional morning diarrhea may be a sign of a temporary illness or the result of lifestyle choices.
However, having morning diarrhea on a regular basis may be a sign of an underlying condition.
Lifestyle causes
Morning diarrhea may be caused by smoking.
Lifestyle choices that may cause morning diarrhea include some of the following common habits:
Smoking cigarettes: Nicotine can cause loose stools. Morning diarrhea may occur if a person smokes before they go to bed or first thing in the morning.
Drinking too much alcohol: Alcohol can also cause loose stools. Morning diarrhea may be caused by drinking too much alcohol the night before.
Midnight snacking: Morning diarrhea may be caused by getting up in the night to eat or snacking before bed.
Drinking too much coffee: Caffeine increases bowel movements. Too much coffee may cause morning diarrhea.
Eating a large breakfast: Having a big breakfast shortly after waking up may overstimulate the bowels, which may cause morning diarrhea.
Taking medication: Medications such as antibiotics can cause morning diarrhea.

Temporary conditions
Temporary conditions that may cause morning diarrhea include:
Food poisoning: Morning diarrhea may be caused by eating food that has passed its shelf life or been contaminated by bacteria.
Virus: A virus such as influenza may cause morning diarrhea.
Bacterial infection: A bacterial infection may cause morning diarrhea.
Pregnancy: Morning diarrhea may be a response to changing hormone levels caused by pregnancy. Changing hormones may also cause morning sickness to occur.
Psychological stress: The bowel can be stimulated when a person is stressed or anxious, which can cause morning diarrhea.
Dehydration: Dehydration affects electrolyte balance. Electrolyte imbalance can stimulate the gut and cause diarrhea, as electrolytes control how cell membranes work and transport electrical signals that cause muscles to contract.
Long-term conditions
IBD, IBS, and allergies may be causes of morning diarrhea.
Long-term conditions that may cause morning diarrhea include:
Why Some People Can't Handle Coffee - Sharp Science
Irritable bowel syndrome (IBS): One of the leading causes of morning diarrhea is IBS. Psychological stress and certain foods may be triggers, but the exact cause of IBS is unknown. Although a 2016 studyTrusted Source found links between anxiety, depression, and IBS.
Inflammatory bowel disease (IBD): IBD is an umbrella term for a variety of conditions which cause inflammation in the gut. Conditions include Crohn’s disease and ulcerative colitis.
Allergies: People who eat foods they are allergic or sensitive to may develop irritation of the gut, leading to morning diarrhea. Common food allergens include peanuts, wheat, egg, dairy, and fruit.
Treating morning diarrhea
When lifestyle factors cause morning diarrhea, a person can make some changes to try to reduce the irritants causing the problem.
If an allergy is responsible for causing morning diarrhea, then the best way to prevent the condition occurring is to cut any irritating foods out of the diet completely.
Anyone who thinks that IBS or IBD is causing the morning diarrhea must see a doctor for an accurate diagnosis. The first step in diagnosing the cause of the morning diarrhea is to identify the symptoms of each condition.
The symptoms of IBS, in addition to morning diarrhea, are:
bloating
stomach cramps
gas
constipation
mucus in stools
The symptoms of IBD, in addition to morning diarrhea, are:
stomach pain
weight loss
fatigue
blood in stool
A doctor can help determine whether a person has IBS or IBD. The treatments for each condition are as follows:
IBS treatments
IBS treatments include:
Antidepressants: Tricyclic antidepressants are an effective treatment for IBS symptoms, despite not being designed for this purpose, according to a 2009 studyTrusted Source. Examples include imipramine (Tofranil) and desipramine (Norpramin).
Anticholinergic medication: These medications may reduce spasms leading to diarrhea. An example of an anticholinergic medication is dicyclomine (Bentyl).
Anti-diarrheal medication: Non-prescription medications such as loperamide (Imodium) may also help. These are available to buy online or over the counter.
IBD treatments
Anti-inflammatory medications for IBD target inflammation in the gut that cause symptoms including:
corticosteroids
aminosalicylates
immunosuppressant drugs
Dietary changes also help to manage IBD. A 2017 studyTrusted Source found that following the autoimmune protocol diet (AIP), which involves eliminating certain foods, could help control IBD symptoms.

Prevention
Spicy foods should be limited as they may irritate the gut and cause morning diarrhea.
Similarly to many other conditions, morning diarrhea is less likely to affect people who lead a healthful lifestyle, eat well, and exercise regularly.
Making positive lifestyle changes to reduce gut irritation, such as stopping smoking or reducing drinking, are good ways of preventing morning diarrhea.
Taking steps to reduce the effects of psychological stress is another good way to promote healthful bowel movements.
Yoga, meditation, and running are all effective ways to reduce the impact stress has on the mind and body.
Limiting quantities of the foods that are likely to irritate the gut is also a good idea. Foods to limit, include:
carbonated drinks
spicy foods
raw fruit
starchy foods that contain gluten
foods that contain FODMAPSTrusted Source, fructose, or lactose, which are types of sugar
Complications
Having diarrhea can cause dehydration. This can affect older people, children, and those with underlying conditions more seriously.
Drinking plenty of fluids to help prevent dehydration is essential if someone has diarrhea.
Food poisoning results in a higher risk of becoming dehydrated.
When to see a doctor
Most causes of morning diarrhea are temporary and soon pass. People should speak to their doctor if the diarrhea does not go away.
The doctor can help diagnose the underlying condition causing morning diarrhea. Causes may include IBD or IBS. Once the doctor has diagnosed the cause, they can recommend appropriate treatment.
If the cause is food poisoning, people are at higher risk of dehydration. They should seek medical attention if they are unable to keep down any liquids and are unable to rehydrate.
Why is coffee suddenly upsetting my stomach?
Nathan loved coffee—he was a barista at a specialty coffee shop—but he started to notice something after a couple of months of work. His stomach was upset… a lot. The discomfort drove him to the doctor, who told him the terrible news:
“You need to stop drinking coffee.”
As my friend told me he’d have to quit working at the cafe, my gut dropped. It seemed like a nightmare. Little did I know how common this series of events is.
Coffee upsets the stomachs of millions of people in the country. If this is you… you’re not crazy. But you’re also not doomed.
There are ways to continue enjoying your daily coffee ritual without all the suffering.
Let’s walk through the reasons why coffee impacts you negatively and how you can fix it.
The 3 Big Reason Coffee Upsets Your Stomach
There are primarily three reasons coffee can make you feel meh down in the stomach. Each one requires a different approach to fixing the issue, so let’s make sure we can nail down which one it is for you.
You’re Body’s Not Fond Of The Caffeine (The Big Problem)
As you undoubtedly know, caffeine stimulates your digestive system (partially by irritating it), which… helps things flow. It’s a natural laxative, forcing your digestive system to work really hard, really fast. But the boost to bowel movement readiness often comes with a bit of discomfort.
And there’s more to caffeine’s dark side—it also triggers your body to produce more acid, which after a lot of caffeine, can lead to so much acid that you get a tummy ache. It’s not harmful. Just not very fun.
This is where most people get their coffee-related stomach discomfort from. The high caffeine levels lead to two issues, not just one. Thankfully, there’s a way to counteract them both (more on this later).
You Have An Acid Sensitivity (The Small Problem)
Coffee is an acidic drink, but it’s not that acidic. Here, we’ll prove it by looking at the pH levels of other common drinks:
Neutral pH: 7
Dasani Water: 6
Black Coffee: 5.7
Coca Cola: 2.5
Lime: 2.2
Here’s what it means: the acids found in coffee aren’t crazy, and unless you have a specific acid sensitivity, the acid is not the problem.
Best & Worst Foods to Eat with Irritable Bowel Syndrome (IBS) | Reduce Risk and Symptoms of IBS
Now, it’s possible that the caffeine is triggering you to produce too much acid—but that’s a bit different from having an acid sensitivity.
You Skipped Breakfast (The Biggest Problem)
Coffee is not a subtle drink. It’s strong, filled with caffeine, acid, oils, aromas—and it’s a lot for your stomach to handle without something else to spread out the impact.
If you drink coffee on an empty stomach, you’re bound to have tummy trouble. The natural laxative effects won’t feel good. Your stomach will probably over-produce acids. It’s just not a good time.
And here’s the thing… this can happen to anyone. Even if coffee’s caffeine never seems to impact you. Even if you have zero acid sensitivity. Coffee on an empty stomach is bad news.
4 Ways To Brew Without The Pain
Now that you know what the real issues are (and which ones aren’t as big of a deal as everyone says… *ehem acid*), let’s get into the easy fixes you can start trying out.
Stop Drinking Coffee On An Empty Stomach (Easy)
Okay seriously. Stop.
Bananas are alkaline and can cancel out some of the coffee’s acids. Milk is the same way. Sugary cereals don’t really do too much for you, so if you can go with something more substantial, like oatmeal or eggs, that’s better.
The goal is to spread the caffeine out among other foods so that you’re not digesting it all within a few minutes.
(Simply drinking your coffee more slowly can also help here.)
Try A Decaf Coffee (Hard)
Here’s a (not so fun) way to see if it’s the caffeine that’s bothering you: quit caffeine for two weeks. Awful, we know. Then add decaf coffee back for two weeks. The lack of caffeine (there’s still a tiny amount left) should leave you feeling much better.
Of course, then you’re not getting caffeine—that’s why we suggest trying the “eating food approach” first.
Give Cold Brewing A Go (Easy)
Cold brew coffee is this magic elixir with 66% less acid and caffeine. The cold water simply doesn’t extract as much as hot water—so the end result is quite different.
It tastes smoother, sweeter, and more aromatic. Not everyone likes that it doesn’t have the same acidic bite or bitter caffeine notes, but it’s absolutely worth trying.
Read the last guide you’ll ever need to make cold brew coffee right here.
And here’s why cold brew is almost a silver bullet when it comes to stomach pain from coffee…
It’s easy on the tummy. 66% less acid and caffeine—solves a lot of problems right there.
It can be drank both cold and hot. Most people add ice to make iced cold brew, but you can absolutely dilute the concentrate with hot water instead for a mostly-normal hot coffee.
You can get really creative with it. From cold brew lemonade to homemade iced cold brew lattes, you’ll never run out of fun ways to drink your cold brew.
It’s really easy to make at home. Just mix coarse coffee grounds and water, wait twelve hours, and strain. Easy! (Here’s that guide again.)
Getting an upset stomach from coffee is a bummer—we know the feeling—but there are several things you can try to fix before you give up on our liquid magic altogether.
You should obviously never drink coffee on an empty stomach, but if you’re looking for a more impactful fix, we’re big fans of the cold-brew route.

It’s so easy, but the trick isn’t in the technique—it’s in the beans.
Always start with freshly-roasted, specialty-grade coffee beans. Otherwise, you’ll end up with a bad-tasting cold brew you hate (and that’s a fast way to ditch cold brew and go back to the stomach aches).
Get the good beans, brew the good cold brew, and live the good life… upset stomach-free.
Can black coffee affect bowel movements?
Many people love their morning cup of joe.
Not only is this caffeine-fueled beverage a great pick-me-up, it’s also loaded with beneficial antioxidants and nutrients (1Trusted Source).
What’s more, some people find it can jump-start the other end of their body.
In fact, one study found that 29% of participants needed to use the bathroom within twenty minutes of drinking a cup of coffee (2Trusted Source).
This article helps explain why coffee can make you poop.
Caffeine Can Activate Your Colon
Coffee is one of the best sources of caffeine on the planet.
Caffeine is a natural stimulant that helps you stay alert.
A single brewed cup provides approximately 95 mg of caffeine (3Trusted Source).
Understanding IBS-D Webinar
While caffeine is a great energy booster, it may also stimulate the urge to poop. Several studies have shown that it can activate contractions in your colon and intestinal muscles (4Trusted Source, 5Trusted Source).
Contractions in the colon push contents towards the rectum, which is the final section of your digestive tract.
Research has shown that caffeine makes the colon 60% more active than water and 23% more active than decaf coffee (6Trusted Source).
However, studies have shown that decaf coffee can also stimulate the urge to poop. This indicates that other compounds or factors are responsible (2Trusted Source, 6Trusted Source).
SUMMARY
Coffee is a rich source of caffeine, which can make your colon and intestinal muscles more active. This helps your body push food quickly to the rectum.
Decaf Can Also Make You Poop
It was initially believed that the caffeine in coffee makes you poop.
However, studies show that decaf can also do the trick. This means there must be other factors at work (6Trusted Source).
Chlorogenic acids and N-alkanoyl-5-hydroxytryptamides are both compounds of interest.
Studies have found that they can stimulate the production of stomach acid. Stomach acid helps churn food and move it quickly through the gut (7Trusted Source, 8Trusted Source).
Several other factors may explain why your morning cup of java can make you poop.
For example, the act of drinking can make the colon more active. This is called the gastrocolic reflex. It’s the same reflex that activates the colon after you eat a meal (9Trusted Source).
While coffee isn’t considered a meal, it may have a similar impact on your bowels (6Trusted Source).
On the other hand, coffee-induced bowel movements may simply be a coincidence.
This is because the bowels are twice as active when you first wake up, compared to while you’re asleep, so they’re primed and ready to go (10Trusted Source).
Your body’s internal clock, also known as the circadian rhythm, helps regulate many processes, including bowel movements (11Trusted Source).
That said, it’s still not clear how much of an impact these other factors have on stimulating your colon. More research in this area would help determine their significance.
SUMMARY
Other compounds in coffee, such as chlorogenic acids and N-alkanoyl-5-hydroxytryptamides, may stimulate bowel activity. Additional factors include the gastrocolic reflex and your body’s internal clock.

Coffee Can Stimulate Hormones
Coffee has also been shown to stimulate hormones that help push food through the gut.
For example, it can increase levels of the hormone gastrin. Like caffeine, gastrin makes the colon more active (2Trusted Source).
One study found that drinking regular or decaf coffee raised gastrin levels by 2.3 and 1.7 times respectively, compared to drinking water (12Trusted Source).

What’s more, coffee may raise levels of the digestive hormone cholecystokinin (CCK) (13Trusted Source).
Not only can this hormone increase the movement of food through the colon, but it’s also linked to the gastrocolic reflex, which makes the colon more active (14Trusted Source).
SUMMARY
Coffee has been shown to raise levels of gastrin and cholecystokinin, two hormones linked to increased colon activity.
WERBUNG
Milk or Cream May Promote Bowel Movements
Freshly brewed coffee is naturally free of additives and preservatives.
However, over two-thirds of Americans stir in milk, cream, sweeteners, sugar or other additives (15).
In particular, milk and cream may promote bowel movements, as they contain lactose. Close to 65% of people worldwide cannot digest lactose properly (16).
People who are lactose intolerant experience symptoms such as bloating, stomach cramps or diarrhea soon after consuming dairy.
This means lactose can trigger the urge to poop in people with lactose intolerance (17Trusted Source).
SUMMARY
Coffee that contains milk or cream may trigger digestive issues in people with lactose intolerance. This may increase gut activity and stimulate the urge to poop.
Does Coffee Make Everybody Poop?
According to one leading study on this topic, 29% of participants experienced an increased urge to poop within twenty minutes of drinking coffee.
Surprisingly, 53% of all the women in the study were affected by this urge (2Trusted Source).
Women may be more prone to this symptom, as digestive conditions like irritable bowel syndrome (IBS) are more common in women than in men (18Trusted Source).
While the post-coffee urge to go appears to be common, it doesn’t affect everyone.
In addition, it’s not clear if this symptom fades away in regular drinkers.
People with IBS and older adults may be more prone to it because their bowels are more sensitive to the effects of coffee.
Those who are lactose intolerant may also be affected by this symptom if they add milk, cream or other dairy products to their coffee.
SUMMARY
Not everyone needs to visit the bathroom after a cup of coffee, but it may be quite common. People with digestive conditions, such as IBS, and those who are lactose intolerant may be more prone to this experience.
The Bottom Line
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.
However, it’s unclear which of these has the greatest impact.
If you struggle to go to the bathroom regularly, a cup of coffee may be the solution.
Can black coffee upset your stomach?
Coffee is one of the most popular beverages in the world.
It can not only make you feel more alert but also potentially offer many other benefits, including improved mood, mental performance, and exercise performance, as well as a lower risk of heart disease and Alzheimer’s (1Trusted Source, 2Trusted Source, 3Trusted Source, 4Trusted Source).
Cutting Caffeine Would Do This To Your Body
However, some people find that drinking coffee affects their digestive system.
This article explores the reasons why coffee may upset your stomach.
Compounds that may upset your stomach
Coffee contains various compounds that may upset your stomach.
Caffeine
Caffeine is a natural stimulant in coffee that helps you stay alert.
A single 8-ounce (240-mL) cup of coffee contains approximately 95 mg of caffeine (5Trusted Source).
Though caffeine is a potent mental stimulant, research suggests that it can increase the frequency of contractions throughout your digestive tract (6Trusted Source, 7Trusted Source, 8Trusted Source).
For example, an older study from 1998 found that caffeinated coffee stimulates the colon 23% more than decaf coffee, and 60% more than water. This indicates that caffeine significantly stimulates your lower gut (9Trusted Source).
Also, some research suggests that caffeine may increase the production of stomach acid, which could upset your stomach if it’s especially sensitive (10Trusted Source).
Coffee acids
While caffeine is often viewed as the reason why coffee may cause stomach issues, studies have shown that coffee acids may also play a role.
Coffee contains many acids, such as chlorogenic acid and N-alkanoyl-5-hydroxytryptamide, which have been shown to increase stomach acid production. Stomach acid helps break down food so it can move through your gut (11Trusted Source, 12).
That said, while some people have reported that coffee may aggravate heartburn symptoms, research is inconclusive and shows no significant connection (13Trusted Source, 14Trusted Source).
Other additives
In some cases, the coffee isn’t what makes your stomach upset.
In fact, stomach upset could be due to additives like milk, cream, sweeteners, or sugar, which more than two-thirds of Americans add to their coffee (15Trusted Source)
For example, approximately 65% of people worldwide cannot properly digest lactose, a sugar in milk, which may trigger symptoms like bloating, stomach cramps, or diarrhea soon after consuming dairy (16).
SUMMARY
Coffee has several compounds that may upset your stomach, such as caffeine and coffee acids. Plus, common additives like milk, cream, sugar, or sweeteners may upset your stomach as well.
Can decaf coffee upset your stomach?
In some instances, switching to decaf may help with an upset stomach.
This mainly applies if caffeine is the culprit of your stomach issues.
That said, decaf coffee still contains coffee acids, such as chlorogenic acid and N-alkanoyl-5-hydroxytryptamide, which have been linked to increased stomach acid production and gut contractions (11Trusted Source, 12).
Moreover, adding milk, cream, sugar, or sweeteners to decaf coffee may cause stomach issues in individuals who are sensitive to these additives.
SUMMARY
Despite being free of caffeine, decaf coffee still contains coffee acids and possibly additives, which could upset your stomach.
Tips to avoid an upset stomach
If you find that coffee upsets your stomach, several things can reduce its effects so you can enjoy your cup of joe.
For starters, drinking coffee slowly in sips may make it easier on your stomach.
Also, try to avoid drinking coffee on an empty stomach. Coffee is considered acidic, so sipping it alongside food could ease its digestion.
Here are several other ways to minimize coffee’s acidity:

Choose a darker roast. A study found that coffee beans that were roasted longer and at higher temperatures were less acidic, which means darker roasts tend to be less acidic than lighter roasts (17Trusted Source).
Try cold-brewed coffee. Research suggests that cold-brewed coffee is less acidic than hot coffee (18Trusted Source, 19Trusted Source).
Choose larger coffee grounds. One study found that smaller grounds of coffee may allow for more acid to be extracted during brewing. This means that coffee made from larger grounds may be less acidic (19Trusted Source).
Moreover, if you enjoy your cup of coffee with milk but are lactose intolerant or feel that milk upsets your stomach, try switching to a plant-based milk alternative, such as soy or almond milk.
SUMMARY
If you find that coffee upsets your stomach, try a few of the tips above. In many cases, reducing the acidity of coffee or avoiding additives may help combat coffee-related stomach issues.
The bottom line
Coffee has several compounds that may upset your stomach.
This includes caffeine, coffee acids, and often other additives, such as milk, cream, sugar, and sweeteners. Apart from caffeine, many of these compounds are also present in decaf coffee.
If you find that coffee upsets your stomach, there are several things you can do to minimize its unpleasant effects. These include drinking it with food, choosing a lower acidic roast, switching from regular milk to soy or almond milk, and cutting back on additives.
Should I stop drinking coffee if it gives me diarrhea?
Common Causes of Chronic Diarrhea
Chronic diarrhea has many causes. Some are caused by disease. This article focuses mostly upon those causes where you can make changes that may result in a rapid improvement in the diarrhea.
This type of diarrhea is usually painless and persistent, and there are no signs of disease such as bleeding, anemia, weight loss, or fatigue. Frequent loose stools are a daily occurrence. There may be occasional normal stools. Despite the need to stay within reach of a toilet, the person is otherwise well.
Very frequently, the diarrhea is due to something in the diet that is taken in excess. Usually this is an excess of a sugar or chemical substance. Common examples are alcohol and caffeine. An excess of alcohol, especially beer and wine, may cause loose stools the next day. The best test is to stop alcohol completely and see if the diarrhea stops. If it does, drinking may be cautiously resumed at a more modest level.
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. Most people can tolerate smaller amounts well.
Some sugars can cause diarrhea. For example, the artificial sugar sorbitol is used as a sweetener. It is often used in diet gums and candies or as a sugar substitute in coffee or tea. It has no calories, but is a known laxative if taken in sufficient amount. Mannitol is another sweet substance frequently found with sorbitol.
Fructose
is a natural calorie-containing sugar found in fruit. It is one reason why large amounts of fruit can cause diarrhea. It may also be found in candies, soft drinks, honey, and preservatives and, in sufficient amounts, can cause diarrhea. Many people notice that their bowel movements are looser and more frequent in the summer when fresh fruits and vegetables are freely available. Moderating intake should help.
Lactose intolerance
is the cause of chronic diarrhea in some people. Lactose is a sugar that is contained in cow’s milk. Its proper digestion requires the adequate presence of an enzyme (lactase) in the wall of the small intestine. Treatment of lactose intolerance initially involves the elimination of all lactose-containing products from the diet. Moderate amounts of dairy or modified dairy products may be gradually reintroduced into the diet as tolerated.
Laxatives
are frequently present in herbal medicines. Senna tea is an obvious example. But herbs with a laxative effect like senna can be found in many other popular remedies. The contents of an herbal remedy may not all appear on the package. Only by stopping the medicine for a trial period can one be confident that it is not the cause of chronic diarrhea.
Other possibilities
Medications
Many regular medicines can have diarrhea as an unwanted side effect.
Is Caffeine Bad For You? What The Science Says!
A list of suspects includes:
misoprostol
antacids containing magnesium hydroxide
laxatives
stool softeners
drugs for “regularity”
alcohol
caffeine
It pays to be cautious of any regularly consumed drug or “natural” remedy.
Allergies
True food allergies are rare as a cause of chronic diarrhea. If an elimination diet is embarked upon (they are very difficult), one must take care not to end up with a nutritionally deficient diet. Supervision by your doctor is important here.
Infections
Occasionally, chronic unexplained diarrhea may be due to an infection with an intestinal parasite. These are more common is some parts of the world. This may be detected in some cases by stool tests, or more accurately by a biopsy of the upper small intestine.
Surgeries
If one is suffering from chronic diarrhea, it is important to note if there have been previous intestinal operations. Diarrhea can sometimes be a complication. Inform your doctor of the precise nature of any previous abdominal surgery, since this type of diarrhea is often treatable.
Summary
If you have chronic diarrhea you should carefully review with your doctor all that you eat and drink, and your past surgical, drug, and travel history. This may disclose a cause that can be remedied.
Careful consideration of these everyday items may avoid extensive and costly tests and lead to earlier relief.
Why can drinking coffee trigger diarrhoea?
There are few things better than a cup of coffee in the morning to get you going for the day. However, coffee can be a wake-up call for both the mind and the gut - and can trigger a sudden urge to go to the toilet. But why does drinking coffee have this effect on our bowels?
Why coffee makes you need the toilet
Coffee is known to stimulate the digestive system, but researchers suggest there could be various different reasons for this reaction. One factor is believed to be the high caffeine content in coffee, compared to other hot drinks such as tea.
"Coffee is one of many food substances that is high in caffeine and the caffeine in the coffee can lead to the gut symptoms experienced," says Dr Bridgette Wilson, a registered dietitian from City Dietitians in London. "Other common foods that are also high in caffeine include tea, energy drinks, cola beverages and dark chocolate."

Various studies support the theory that caffeine has a laxative effect. In one study, researchers gave participants either water or caffeine powder dissolved in water and measured their anorectal function. The results suggested that ingesting caffeine led to stronger anal sphincter contractions and an increased desire to poo.
"Caffeine is a gastrointestinal stimulant which means that it speeds up peristalsis (muscle contractions that move food through the digestive tract)," says registered dietitian Caroline Bletcher. "Therefore it speeds up transit through the bowel, resulting in symptoms such as diarrhoea and stomach cramping."
However, research has suggested there may be other factors at play too. Both caffeinated and decaf coffee stimulate the production of a hormone called gastrin, which signals the stomach to release gastric acid. As gastrin promotes digestion, it may contribute to our urge to go to the toilet after drinking coffee.
Another reason why coffee impacts our bowels is the gastrocolic reflex - a physiological response in which the act of eating or drinking stimulates movement in the gastrointestinal tract. Therefore, the activity of drinking a cup of coffee with breakfast may be enough to trigger the need to 'go'. Additionally, this reflex is more reactive in the mornings, which is when many people reach for their cafetiere.
The acidic nature of coffee can also stimulate the bowels, which may explain why some people experience stomach trouble with decaffeinated coffee as well as regular coffee. Both decaf and caffeinated versions contain chlorogenic acid, which triggers higher stomach acid levels and higher production of gastric acid. In turn, this acid helps to move food through the gut.

Can coffee affect irritable bowel syndrome?
"People with irritable bowel syndrome (IBS) may have a more sensitive gut and therefore the effect of caffeine could be more pronounced," says Wilson. "Caffeine is what is known as a stimulant, meaning that it can lead to over-excitation of the nervous system, including the nervous system attached to our gut.
"When the gut nervous system is overstimulated, it can lead to increased contractions within the large bowel, leading to cramping sensations and looser and more urgent stools. Some people with IBS already experience symptoms associated with over-stimulation of the gut nervous system. So, coffee and other sources of caffeine could make this worse."
However, Wilson adds, it is worth remembering that there are many causes of IBS and people react differently to substances like coffee. "Not everyone with IBS will have an over-excited gut nervous system, so for those people caffeine is no more likely to lead to gut issues than in people without IBS," she says.

What can you do to negate the negative effects of coffee?
Of course, getting things moving along isn't always a bad thing. It is generally advised that people limit their caffeine intake to 400 mg a day, which is between three to five cups. Pregnant women should consume no more than 200 mg of caffeine a day. However, some people may be more sensitive than others to the effects of a flat white.
Cut down your coffee intake
Those who struggle with stomach problems after drinking coffee may find it useful to cut down their caffeine intake. Decaf or half-caffeinated coffee may help and there is some research to suggest that the type of coffee consumed could have an impact too. In 2014, a study suggested that dark roast coffee produced less stomach acids than a medium roast, due to its different balance of chemicals.

Don't drink coffee on an empty stomach
Although many people reach for the coffee machine before breakfast, drinking a fresh brew on an empty stomach may exacerbate negative effects like diarrhoea and stomach cramps. Having a coffee with or after food may help.
Be wary of extras
Sometimes, how coffee is taken can have an effect too. Some may find that adding cow's milk, cream, syrups, sugar or sweeteners can trigger stomach discomfort.
However, coffee sensitivity is personal and it may be a case of trial and error to find out what works best.
