To talk about an input of coffee and an output poop in the same phrase conjures up two images that generally shouldn't be associated with each other. However, there is a real connection between these two topics and finding out why coffee makes you poop speaks to a major health benefit of drinking one of the world's most popular beverages.
Coffee has long been linked to many health benefits from increased mental focus to extra boosts of energy. One of the lesser known health benefits of coffee is that it effectively stimulates movement and activity in the colon. What this means in blunt terms is that coffee makes you poop.
For those wondering why they always feel the need to poop after drinking coffee, there's a reason. And it's not because you're weird.
One might suspect that it's the caffeine that's responsible for all of this. However, other caffeinated products such as soda don't have that #2 effect. Studies have also shown that decaffeinated coffee is also known to prompt a post-coffee visit to the bathroom. While scientists say they don't the precise reason for why this happens, they say coffee affects the epithelial tissue which is the lining of the small intestine and stomach. Coffee of any kind will stimulate a number of chemical processes that result in higher acidity in the stomach. This acidity boost can cause the stomach to empty out faster than normal. Additionally, coffee promotes the release of a peptide hormone called Gastrin which activates the colon. It can get a lot more technical than this but ultimately, coffee can play a similar role as a laxative. Within as little as 4 minutes of drinking coffee, you can experience the near immediate effects of one of the world's most effective and best tasting laxatives.
Interestingly enough, this effect is said to happen in only 30% of coffee drinkers. So if you're one of these lucky 3 out of 10 drinkers you have a most enjoyable way of maintaining regular bowel movements. Getting rid of waste is a cornerstone to health and coffee used in moderation can be an integral tool to keeping your body cleansed.
