How long does brain fog last after eating gluten?
It takes approximately 48 hours on average for brain fog symptoms to resolve after accidentally eating gluten. This study found that neurological symptoms are common in non-celiac gluten sensitivity (NCGS). The most common neurological symptoms were headaches, brain fog, balance issues, and tingling. The onset time of these symptoms was similar to that in celiac disease, with symptoms typically resolving within 48 hours.
