It is a widespread infection across the world, but for most people there are no symptoms. It is not usually the cause for reflux symptoms.

Has anybody here had false negative results on an H. Pylori test? My breath and stool tests came back negative, but I'm wondering if it makes sense to give it another look, since infection/overgrowth still seems like a reasonable guess for my current woes.

I have bloating and heartburn that has come on very rapidly after taking a mild antibiotic, and persisted for months after stopping. I'm 19 BMI, don't drink, and mostly cook veg-heavy meals at home. Almost no fast food and the like. Never had this problem in my life beforehand. It seems like there's a clear cause and effect at play, but nothing's showed up in the tests so far. Kind of stumped how to follow it up without sounding like a crazy person to the doc.

Do you remember what the antibiotic was called?
