That fizz you love is actually carbon dioxide gas under pressure. When you drink it, that gas expands in your stomach like a tiny, invisible balloon. Your stomach doesn’t appreciate being turned into a party blimp.
This expansion stretches your stomach walls, which can trigger pain and bloating almost instantly. Think of it as your gut sending you a very clear memo: “Stop inflating me, I’m not a pool float.”
If you chug it quickly (we’ve all been there), you’re basically giving your belly a pressurized bubble bath. No wonder it protests.
