Not all doctors treat SIBO. That sounds bizarre, but it's true. Ask the office if they do treat SIBO before making an appointment. After going to traditional doctors, we finally went to a functional medicine doctor for my daughter. I was hesitant at first, but it's a whole new refreshing perspective. She did the breath test and was found to be really high for both hydrogen and methane gases. He prescribed Xifaxan (some insurances cover it, some don't) and it did help. SIBO is hard to get rid of so we'll see how it goes. There are also natural antimicrobials that can help if you can't get the antibiotic. Look into Atantril. There's a lot of info online, but also try reading a book called Sibo Made Simple. It's like an encyclopedia for SIBO. Best wishes.

Are you taking any NSAIDs like ibuprofen or aspirin because I discovered I had an allergy to NSAIDs which caused diarrhea. My GI figured that one out fast. Take a bag and put everything you take like OTC meds, vitamins, pills, prescribed meds, herbal teas, etc and a list of what you eat and drink to that GI appointment. My father and my brother both MDs always had their patients do this. The GI may figure out your problem.
