The real secret to seltzer’s power isn’t the bubbles themselves—it’s the burp. When you drink plain seltzer, those CO₂ bubbles accumulate in your stomach, creating pressure. That pressure triggers your lower esophageal sphincter (fancy name for the burp door) to open wide.
Think of it like shaking a soda can and then cracking it open. You’re forcing a burp, which relieves trapped gas that might have been causing that lower, painful pressure in your intestines. One big, satisfying belch, and you’ve evacuated the enemy. Feels good, right?
In fact, a 2002 study in the journal Digestive Diseases and Sciences found that carbonated beverages can increase the frequency of burping by up to 50%. That’s like having a small, fizzy car mechanic for your digestive system.

Here’s where the joke gets a little dark. If you’re the type who can’t burp (yes, that’s a real condition called retrograde cricopharyngeal dysfunction, or R-CPD), seltzer is your worst enemy. You’ll just fill your stomach with foam, and that foam has to go somewhere—usually south, into your intestines.
Once those bubbles leave your stomach, they travel to your colon, where bacteria have a party. That party creates methane, hydrogen, and sometimes--spectacularly--sulfur. In other words, seltzer can turn a mild bloat into a stinky, gurgling symphony.

So the rule is simple: if you can burp like a champion, seltzer helps. If you’re a silent but deadly type, seltzer adds fuel to the fire.
