Well I've got confirmed dysbiosis (GBT) from overprescribed antibiotics and from my experience, and reading up in those communities you're so contemptuous about, I get the sense that gut dysfunction manifests in seemingly random ways, a whole constellation of weird symptoms. You just feel horrible, sometimes there's no clear cause and effect, it seems random.

I agree there is a lot of just blatant nonsense and maybe they do misuse leaky gut but I think the medical community has a habit of vilifying people who are suffering real problems. I can't tell you how many times I've had a real medical issue (be it a bacterial infection, virus, or most recently, gut dysbiosis) and my doctor blames it on anxiety and offers me lexapro.
