Based on the existing literature that IBD is associated with impaired mucus barrier function, and with high concentrations of sulfide-producing bacteria and sulfide itself in the gut of both human and animal IBD models, we argue that this novel mechanism of sulfide-mediated mucus barrier-breakage could contribute to the pathogenesis of IBD. I think that this is due to the fact that it isn’t screened for in most of the advanced functional gut testing options. A reader ping me about Hydrogen Sulfide(H2S) breath tests and Small Intestinal Bacterial Overgrowth. First, test for SIBO using a breath test Note: If the cause of the problem is associated with the presence of Iron Reducing Bacteria, Sulfate Reducing Bacteria, and elevated levels of hydrogen sulfide, iron, manganese and other problems.
