Well the more correct term is increased or decreased intestinal permeability. Which very much is a thing.

But yeah you’re not completely wrong to be skeptic about the so called “leaky gut syndrome”, but that’s why you have to remember what syndrome means; just a collection or symptoms. People could have a collection of symptoms from different sources which still amount to the same syndrome. (Usually not though, but technically.)

Is the Gulf War - syndrome “woo bullshit” or real? Because if we apply the same standard as I presume you’re applying to the leaky gut syndrome, I presume you’d say it’s BS as well. Yet I bet there’s quite a lot of nasty vets who you wouldn’t dare to say that to their faces.

So just to reiterate; leaky gut syndrome, highly dubious en.m.wikipedia.org/wiki/Leaky_gut_syndrome

But increased intestinal permeability, also known as “leaky gut”: very much real but distinct from the other one en.m.wikipedia.org/wiki/Intestinal_permeability#C…
