Why Do I Poop After Drinking My Morning Coffee?
Many people experience the urge to poop after drinking coffee in the morning. Does coffee really act as a laxative? Well, maybe. There could be a few different reasons coffee triggers bowel movements.
First, caffeine is a stimulant. Just as it stimulates your nervous system, it can stimulate your digestive system. Second, drinking hot coffee can be stimulating on the colon because hot beverages tend to move the digestive process along.
Third, one study of coffee consumption showed that coffee can activate the release of cholecystokinin, a hormone in the intestines linked to bowel stimulation.
Why Does Pooping Sometimes Feel So Good?
Pleasurable sensations when pooping can be caused by one major nerve. The vagus nerve connects the digestive tract all the way up to the brain. When having a large BM, the rectum can press against the vagus nerve and stimulate it.
Dr. Anish Sheth, a gastroenterologist and co-author of What’s Your Poo Telling You?, explains how it works. “The net effect of this is a drop in your heart rate and blood pressure, which in turn decreases blood flow to the brain. When mild, the lightheadedness can lead to a sense of sublime relation — the high.” That high is what Dr. Sheth calls poo-phoria.
Why Does Pooping Hurt Sometimes After Eating Spicy Foods?
You’d think those chili spices would go in hot but come out mild, right? Unfortunately, that’s often not the case. Spicy foods can retain their heat as they move through your digestive tract. Keep that in mind before you eat painfully hot foods. It’s not just your mouth that could burn as they pass through.
The science behind burning BMs has to do with the effect of a chili pepper extract called capsaicin, which many spicy foods contain. Capsaicin that moves through the colon can attach to and stimulate pain receptors in the anus when you poop.
