Many sodas contain caffeine, which is a natural stimulant. Caffeine tells your colon, “Hey, let’s get moving!” and speeds up digestion—sometimes way too fast. That can lead to urgent trips to the bathroom and cramping.
If you’re not a regular coffee drinker, even a little cola can act like a laxative with a party hat. Your stomach might say, “Nope, we’re not doing this today,” and send everything into express delivery mode.
Combine caffeine with sugar and carbonation, and you’ve got a trifecta of tummy trouble. It’s like a fireworks show in your gut, but without the pretty colors.
