Another great post from the Paleo Mom
She has Hashimotos and is a scientist.
For those with celiac disease, one study showed that only 66% of patients had a normal intestinal biopsy after 5 years on a gluten-free diet 6. This means that even after 5 years, 34% of Celiac Disease sufferers had not recovered. There are no good similar studies evaluating intestinal repair in people with non-celiac gluten-sensitivity, but medical professionals who specialize in treating gluten-sensitivity report time frames of approximately 1½-2 years 7.
