I can’t remember, did you have a negative breath test for sibo? Mine was negative, yet even the gastrologist is convinced that I have overgrowth. As you said, there must be other factors that have not yet been discovered.e been trying to find out what is driving the Overgrowth; but there are so many possible factors, even diverticular pockets could allow for some of the Bacteria to be protected or even Biofilms, where bacteria act together to produce a protective layer around colonies of sometimes different Bacteria, which is another method or antibiotic resistance.
In another post, there is discussion on temporary relief from colonoscopy prep, which further suggests this.
Have you tried to take herb/ supplement, anti microbial/ biofilm breakers? I am trying several things, but my stomach/ reflux is not cooperating. So far I’ve only been able to take tiny amounts of colostrum. Berberine and allicin are too harsh. Cistus tea is a powerful biofilm breaker, but again, I cannot tolerate tea.
Someone I’ve recently met suggested fructose malabsorption. Not fructose intolerance, which is a hereditary condition. Fructose malabsorption would be a gradual build up of fructose in the gut, due to a lack of enzymes to break them down. I would think, that in turn would create a food supply for opportunistic bacteria. I wouldn’t necessarily consider this a root cause, but possibly a secondary issue from dysbiosis.
My question would be, although I do not eat anything that obviously contains fructose, do wheat, corn, vegetables, things that I am eating, contain enough fructose to be a problem? If so, this could explain how the no-carb diet reduces symptoms. There is an enzyme product, xylose isomerase, that aids with breaking down fructose.
