Yes. It can appear at any age, even in people who previously tolerated gluten. Environmental triggers and gut infections can activate genetic susceptibility.

You may have non-celiac gluten sensitivity. Your doctor can help differentiate this condition through elimination diets and specialized tests.

In children with very high antibody levels, yes  but most adults still require biopsy for confirmation.

No. You must continue eating gluten before testing, or your antibody levels may normalize, giving a false-negative result.

It involves antibody blood tests (tTG-IgA, EMA) followed by a small intestine biopsy to confirm villi damage. Genetic testing may also support the diagnosis.
