Some people swear that burping helps nausea. They’re not wrong. A big, loud belch can temporarily relieve pressure.
But that carbonation is also carbonic acid. It can irritate an already inflamed stomach lining. Think opening a shaken soda on a fresh wound—same vibe.
And don’t get me started on the caffeine. Caffeine is a mild diuretic. It makes you pee. And it can stimulate your bowels. That’s the last thing you need when you’re already running to the bathroom every twenty minutes.
But… What About the “Flat Coke” Trick?
Ah, the wisdom of letting it go flat! The idea is that leaving the soda out kills the bubbles, making it gentler. You’re just left with sugar water.
But here’s the kicker: flat soda still has tons of sugar. That sugar still does its osmotic water-pulling magic. You’re just drinking sad, warm, syrupy chaos.
Studies have actually shown that flat cola is worse than plain water for rehydration. The World Health Organization does not recommend it for diarrhea. And they know their poop.
