Spicy food gets blamed for reflux constantly, but the evidence is more mixed than the reputation suggests. Capsaicin, the compound that makes food spicy, doesn't relax the LES the way caffeine or alcohol does, and some research suggests it may even speed up stomach emptying, which could theoretically help rather than hurt. What does seem to matter is direct irritation: capsaicin can aggravate an esophagus that's already inflamed from reflux, making existing symptoms feel more intense even if the spicy food didn't cause the reflux episode itself. This explains why some people with reflux tolerate spicy food fine, while others feel a clear flare-up. If spicy food seems to correlate with your symptoms, it's worth treating as a personal trigger — but it's not a universal one the way caffeine or fatty food tends to be.
