First, let’s talk about the bubbles. Those tiny, happy bubbles? They’re actually expanding gas in your stomach. Your belly gets bloated, pressure builds, and suddenly the door to your stomach (the lower esophageal sphincter) gets a little loose.
Think of it like a shaken soda bottle. When you burp, you’re releasing that pressure—but sometimes, you release a little stomach acid along for the ride. Classic reflux move. Not so fun when it’s your own stomach doing the shaking, right?
