Mark Pimentel developed a breath test called TrioSmart that detects hydrogen sulfide producing bacterial overgrowth. He promotes the use of Xifaxan plus Pepto Bismol to treat these patients who tend to have problems with diarrhea and abdominal pain. It seems that about a quarter of H2S producing patients are constipated, instead of having diarrhea. I have found that a low carb diet corrects this H2S bacterial overgrowth even if you don’t treat with antibiotics and Pepto Bismol. But then again, a low carb diet corrects insulin resistance. Maybe it works because it causes the H2S producing bacteria to wither away.

Thanks Nick! So how much Pepto Bismol a day to treat the presence of hydrogen sulfide?

(While also eating a low carb diet)
