Here’s the science-y part, but I promise I’ll keep it fun. Coffee is naturally acidic. It’s basically a tiny, delicious science experiment swimming around in a mug.
That acidity can irritate the lining of your stomach, especially if you drink it on an empty stomach. Your stomach then goes, “Whoa, buddy! What’s the big idea?” and starts producing extra acid to deal with the invasion.
And then there’s caffeine. It’s not just a pick-me-up; it’s a “get-everything-moving” kind of chemical. It stimulates your colon, which is great if you’re constipated, but less great if you have plans that don’t involve sprinting to the bathroom.
The “Caffeine Jitters” Meets the “Gut Gurgle”
It’s a double whammy. You get the jitters in your hands, and the gurgles in your gut. It’s like your body is having a tiny, internal house party without your permission.
Some people are just more sensitive to these effects. I, apparently, have a stomach that acts like a grumpy librarian—“Shhh! No fun allowed!”—every time I try to enjoy a latte.
But don’t throw your favorite mug against the wall just yet. There are ways to make peace with your beloved bean water.
