Coffee not only makes us wake up in the morning, for many of us it is what causes our bowel movements in the early morning. Some of us can’t even have our daily poop without having our coffee first. How and why does coffee cause us to have a bowel movement when we drink it?
Typically, it’s the caffeine in coffee that does the trick in urging you to poop. The high amounts of caffeine, in addition to the acidic oils in coffee, encourage the muscles in your digestive tract to contract, causing your sphincter muscles to contract right along with them. This pushes the wastes in your digestive tract into your colon, and soon you feel the urge to poop after a cup or two of your favorite brew. The oils in the coffee also can cause stomach upset, which is why sometimes when we defecate it comes out more runny, and oily instant coffees can cause diarrhea like none other. The stronger the brew, the oilier the concoction, the more caffeine and oils you have upsetting your digestive tract, and the sooner you better find a toilet before you blow.
So if you rely on your daily cup of joe to have a decent bowel movement in the morning, it’s not a surprise. As a diuretic as well, though, coffee isn’t the best remedy for constipation, since it actually leeches more water from the body and can make constipation even worse. A cup or two of coffee can get your bowels moving though, and to really get you moving, try a cup of instant coffee, and I bet you can’t get through a whole cup before you need to go to the john.
