Now, sugar. Soda is packed with it—or high-fructose corn syrup. That stuff slows down digestion. Your stomach has to work overtime, and a full, slow stomach is a reflux machine.
Plus, soda is incredibly acidic on its own. Some sodas have a pH around 2.5—that’s basically battery acid territory (okay, slight exaggeration, but you get the point). Your stomach acid is already strong; why add more acid to the party?
Oh, and the caffeine? Yep, it relaxes that same valve between your stomach and throat. So you’re getting acid and a loose door. Great combo, right?
But wait—does everyone get reflux from soda?
Here’s the thing: your mileage may vary. Some people can chug a can of Coke and feel fine. Others have one sip and feel like a dragon is breathing fire up their throat. Lucky them, right?

If you already have a weak lower esophageal sphincter—or a hiatal hernia—soda is like throwing gasoline on a campfire. If you don’t? You might get away with it for a while. But habit matters.
Drink soda every day for years, and you’re basically training your stomach to be a reflux volcano. Your body adapts, and not in a good way.
