It takes 6-8 weeks for the gluten to fully leave your gut tissues, and another 6-8 weeks for damage to heal. If you notice symptom relief within that time frame, then you have your answer. If you don't, but then do a gluten challenge (i.e., add gluten back to your diet) and get symptoms or current issues become worse, then you also have your answer. Sometimes it takes up to a year or more gluten-free for people to really have noticeable changes, and other times the change is noticed within a few days. It depends on the individual.
