Does Decaf Coffee Make You Poop Like Regular Coffee?

I must admit, I am an avid coffee drinker. I start each day with a steaming cup of joe, savoring the rich aroma and the energizing effect it has on my body. However, like many coffee lovers, I have experienced the occasional discomfort that comes along with my favorite beverage – the urgent need to use the restroom. It got me wondering, does decaf coffee have the same effect on the bowels as regular coffee? In this article, I will explore the relationship between decaf coffee and bowel movements and try to answer this burning question.

Understanding the Basics:

Before we dive into the depths of decaf coffee and its effect on our digestive system, it’s essential to understand the basics. Coffee, whether regular or decaf, contains a compound called caffeine. This stimulant is known to have a laxative effect on the body, meaning it can increase bowel movements and potentially lead to the urge to poop.

The Role of Caffeine:

Caffeine stimulates the muscles in the digestive tract, particularly the colon, which is responsible for moving waste through the body. When the colon muscles are stimulated, they contract more frequently, expediting the transit time of waste material. Thus, the bowels may become more active, resulting in the urgency to use the restroom.

Decaf and Caffeine Content:

Decaf coffee, as the name suggests, is coffee that has had the majority of its caffeine content removed. However, it is essential to note that even decaf coffee is not entirely caffeine-free. The decaffeination process typically removes about 97% of the caffeine, leaving behind a trace amount. So, while decaf coffee has significantly less caffeine compared to regular coffee, it still contains a small quantity that can influence bowel movements.

The Debate:

Now that we have a basic understanding of the role of caffeine in regular and decaf coffee, let’s address the question at hand – does decaf coffee make you poop like regular coffee?

Research Studies:

Numerous scientific studies have investigated the effects of caffeine on bowel movements, but fewer studies have specifically examined the impact of decaf coffee. One study published in the Journal of Clinical Gastroenterology found that both caffeinated and decaffeinated coffee had a laxative effect compared to water. The study concluded that decaffeinated coffee had a slightly smaller effect, but it was still significant when compared to a control group.

Individual Variations:

It’s important to consider that individual variations can play a significant role in how our bodies react to decaf coffee. Some people may be more sensitive to small amounts of caffeine, while others may experience no difference between regular and decaf coffee. Factors like age, overall health, and gut microbiota can all contribute to these individual variations.

Psychological Factors:

Another aspect to consider is the potential psychological influence of coffee consumption. Many of us associate coffee with that morning ritual, an opportunity to relax and enjoy a moment of peace. This anticipation and experience of drinking coffee can trigger the body’s “rest and digest” response, leading to increased gut activity and potentially resulting in the urge to use the restroom.


After delving into the topic, it’s safe to say that decaf coffee can indeed have a laxative effect, although it may be milder compared to regular coffee due to its lower caffeine content. The trace amounts of caffeine found in decaf coffee can stimulate the colon muscles and facilitate bowel movements. However, individual variations, psychological factors, and other ingredients present in coffee may also contribute to the overall effect on bowel movements.

So, if you find yourself feeling the need to use the restroom after enjoying a cup of decaf coffee, rest assured that you are not alone. Just know that the impact may be slightly different compared to its caffeinated counterpart. As always, it’s essential to listen to your body and make adjustments based on your personal preferences and tolerance. So, raise your mugs, whether filled with regular or decaf, and enjoy your favorite beverage without the fear of an unexpected trip to the bathroom!
