Does Decaf Coffee Make You Poop?

According to online data, it has been found that decaf coffee can also have a stimulating effect on bowel movements. While the name suggests that decaf coffee is completely caffeine-free, it still contains some caffeine. A 2022 study indicated that regular coffee may have a stronger impact on the colon compared to decaf coffee.

Why Does Decaf Coffee Make You Poop?

Why Does Decaf Coffee Make You Poop

Gut Stimulation

One of the main reasons decaf coffee can make you poop is because it stimulates your gut. The warm liquid can help to relax the muscles in your digestive tract, which can help to move things along. Additionally, the acidity of coffee can irritate the lining of your stomach and intestines, leading to an increased need to go to the bathroom.

Coffee Can Stimulate Hormones

Another reason decaf coffee can make you poop is that it stimulates the release of hormones. Coffee contains caffeine, which is a central nervous system stimulant. When you drink coffee, it increases the production of hormones like adrenaline and cortisol. These hormones can help speed up your digestion, leading to a trip to the bathroom.

Additionally, coffee can stimulate the production of gastrin, a hormone that helps regulate the production of stomach acid. When there is too much acid in your stomach, it can cause discomfort and lead to diarrhea. So, while decaf coffee may not have caffeine, it can still stimulate the release of hormones affecting your digestive system.

Worsening IBS symptoms

Decaf coffee can make you poop because it can worsen symptoms of irritable bowel syndrome (IBS). IBS is a common disorder that affects the large intestine and can cause various digestive symptoms, including diarrhea, constipation, and abdominal pain. Many people with IBS find that even decaf coffee can trigger their symptoms.

The reason coffee can worsen IBS symptoms is not entirely clear, but it may have to do with certain compounds in coffee that can irritate the digestive system. For example, coffee contains caffeine, a stimulant that can increase bowel movements. Even decaf coffee contains small amounts of caffeine, which may be enough to trigger symptoms in some people.

In addition to caffeine, coffee contains other compounds that can irritate the digestive system, such as chlorogenic acid and N-alkanoyl-5-hydroxytryptamides. These compounds can stimulate the release of gastric acid and increase the motility of the digestive system, leading to diarrhea and other digestive symptoms.

Milk or Cream May Promote Bowel Movements

Another reason why decaf coffee can make you poop is that many people add milk or cream to their coffee, which can promote bowel movements. Milk and cream contain lactose, a type of sugar that can be difficult for some people to digest. When lactose is not properly digested, it can pass through the digestive system and ferment in the colon, leading to gas, bloating, and diarrhea.

In addition to lactose, milk and cream contain fat, which can stimulate the release of bile acids and promote bowel movements. This is because bile acids help to break down fat in the small intestine, but when they reach the colon, they can have a laxative effect.

What Role Does Gastrin Play In The Relationship Between Decaf Coffee And Bowel Movements

Gastrin is a hormone that plays a significant role in regulating bowel movements. Decaffeinated coffee can increase gastrin production, which, in turn, prompts the stomach to produce more acid. This acid production helps to facilitate digestion and aid in bowel movements. While the effect is less with decaf coffee, it is still present. Therefore, if someone experiences constipation or irritable bowel syndrome, drinking decaf coffee may help promote regular bowel movements.

However, it is important to note that too much coffee or caffeine can also lead to digestive issues, so one should consume it in moderation.
