I feel like I could have written this all myself — the embarrassment of intermittent fart breath has caused me to dread social interactions.

I have diagnosed celiac for 10 years, but don’t have any symptoms if I eat gluten. I suspect I might have h2s sibo but my GI doesn’t think it’s a clinically valid diagnosis, so have been doing my own testing.

I have a few things that have definitely helped me (partnering with ChatGPT for ideas)

1) Pepto Bismol / Devrom (key ingredient is bismuth). This doesn’t solve the root cause but bismuth binds with hydrogen sulfide and neutralizes the bad smell. I don’t take it always since it’s bad on kidneys but for social events I typically take every few hours (up to max recommended daily dose). Important to start a day or 2 before you need it. Most recently was at a 4 day wedding trip, eating and drinking and nobody pulled back from talking to me (usually it would happen with 1 alcoholic drink).

2) Molybdenum supplements — this also binds with hydrogen sulfide, generally safe to use. This isn’t perfect but my breath feels less harsh (hard to explain) and definitely reduces frequency of smell but still have it. Added benefit of significantly reduced hangovers and for me lower heart rate while drinking (not sure if related symptom but my heart rate typically elevates when drinking)

3) Metamucil tablets (5x 3x / day). Not sure why this helps, but psyllium husk apparently combines with water and can help turn into a gel which can prevent leaky gut I suppose. This is recent for me in past week but have not had anyone complain so far since I’ve been on it so fingers crossed.

No idea what will work for you but haven’t seen these mentioned recently in this thread (besides someone mentioning metamucil also helped them).

Wishing everyone the best with their symptoms, it’s an awful disease
