You would need to take the breath test to find H. Plylori. The scope probably wouldn’t find it. It measures gases, hydrogen and methane, I believe. You will have to blow into a bag, then drink a liquid, wait 15 minutes, and blow in the bag again. For SIBO, you need to take a breath test as well. I didn’t even have most of the symptoms of H. Plylori. I would get occasional abdomen pain, and the fart odor coming from my mouth. If it wasn’t for the odor, I could tolerate the occasional pain.
