celiac disease is caused by dysbiosis and leaky gut, it does not cause dysbiosis or leaky gut.
It is a bi-product of dysbiosis.
Not everyone suffering from dysbiosis develops celiac disease, but most of the people who developed celiac disease, are actually suffering from severe dysbiosis and have been suffering from dysbiosis before they developed celiac.
I remember reading a case where gluten intolerance was cured by fecal transplant.
Fecal transplant, so far, is the most powerful treatment for severe forms of dysbiosis, and diseases caused by severe forms of dysbiosis like UC, Crohn's, Alzheimer's, Parkinson's, MS, ALS, Candidiasis, etc.
If you read moderna medical books or modern medical sites written by modern doctors, you will find hundreds of places where they got it all upside down.
