Question: Is hydrogen sulfide produced in the gut a bad thing, and what to do about it?I agree that most people that have this problem have some kind of deranged sulfur metabolism, but I don't see why that makes it a physiological adaptation rather than a pathological condition. The correlation is probably a direct result of the predominance of sulfur-metabolizing bacteria in the gut, which is a bad thing that is actually causing the derangement of sulfur metabolism. Well, you could go the antibiotic route. And I think metronidozole, and let me see if I can dig this up quickly because I have done a lot of research on this issue for one of my clients. Okay. So from the research I was looking at, metronidozole is very effective against sulfur-metabolizing bacteria. But isn't that reliably delivered to the stool and maybe could be used as an enema. But I think generally, it is used. And then I think there's one other one that's sometimes used. I forgot what the other one is. I think it's... Okay. I can't find it. Anyway, you can go the antibiotic route under the guidance of a prescribing specialist. This Q&A can also be found as part of a much longer episode, here.
