Caffeine and Your Colon

Why Does Coffee Make You Poop

One cup of a brewed coffee has about 95 milligrams of caffeine(source).

While this amount is enough to give you an energy boost, it is also enough to stimulate your colon causing it to contract and push your digestive system’s contents down towards your intestinal muscles and rectum.

This digestive process will give that urge to poop. Well, pooping is done best every morning anyway and you take your first cup of brew as the sun rises so this can be healthy for you.

After all, coffee is considered a promotility agent.

Acid and Bile

Brewed beverages are usually acidic in nature and coffee is no exemption to this. Apart from caffeine, coffee is also acidic and this one will lead your body to create more bile.

Bile is the alkaline-y and bitter substance that helps in making your tummy churn(source). The bile that is being produced can cause a build-up inside your gut thus causing you an upset stomach and dose of diarrhea.


Coffee and Your Hormones

Studies show that coffee also stimulates hormones that help push food down.

It specifically increases the level of gastrin and this hormone makes your colon very active. Compared to water, coffee can push your gastrin level up by 2.3%.

Aside from increasing your gastrin hormone level, coffee also affects your digestive hormone named cholecystokinin.

This promotes the movement of your food through your colon and makes the colon more on the go.

Coffee and your Cream

This is one plausible reason why after drinking coffee, you’d want to sit on your bathroom throne. Coffee that is freshly brewed contains zero preservatives and additives but most coffee drinkers have their preferences when it comes to their coffee.

So a probable culprit on why you get the urge to poop will be the milk or creamer that you add into your coffee.

These two elements encourage bowel movement because of their lactose content. Almost 65% of people are unable to fully digest lactose and if you have lactose intolerance, you’ll be familiar with that feeling of being bloated. Stomach cramps and diarrhea is also expected after your dairy consumption.

If you are fond of adding milk or creamer to your coffee and that is the only time that you get that call to the bathroom, then you might want to check if your digestive system can process dairy. Try not to add dairy and see if there will be any different.

Coffee and Coincidence

Meanwhile, drinking coffee and having the urge to poop can also be completely a coincidence.

Upon waking up, your bowels that were also resting become twice as active. It doesn’t automatically go to your rectum after getting out of bed but will take some time before it wants to be released.

As your gastrointestinal tract wakes up after being inactive during the night, it begins its process and by the time you’re done with your morning coffee return, so is the food you ate yesterday ready to be flushed out.

You can also blame it on your internal body clock or a circadian rhythm that is responsible for making every process – pooping included – to be right on schedule.

So, if your post-coffee poop happens only in the morning, then don’t blame it all on the coffee.
