Many people think that the need to poop comes from caffeine in coffee, but decaffeinated coffee has the same effect without caffeine.

Also, no one feels the need to relieve themselves after drinking a soda, so what is the problem?

Thus, scientists have found that coffee stimulates the distal colon, which is the last part of the colon.

This means that when the distal colon is stimulated, it pushes the waste out of the body more quickly – which gives it the urge to poop.

But why does coffee stimulate the distal colon? According to Men’s Health , coffee can also stimulate the production of hormones.

Motilin (a hormone that stimulates intestinal contractions), as well as gastrin (a hormone that causes the secretion of acid in the stomach) can both perform functions that have the effect of having to go to the bathroom after coffee.


The Washington Post reports that chlorogenic acid in coffee can also increase the production of gastric acid in the stomach.

When the levels of gastric acid increase, the stomach needs to return its contents more quickly, pushing it towards the intestines, and then, finally, towards the outside.

Scientists also speculate that some of the other chemicals in coffee may speed up bowel movements, but it is not entirely clear which chemicals are responsible.

Although caffeine may not be the main culprit, The Huffington Post reports that caffeine can have a laxative effect due to the way it stimulates muscle contractions in the large intestine, especially in more sensitive people.

Are you part of the 30 percent of people who discover that they regularly have to poop after drinking a cup of coffee?
