Celiac Disease
While celiac disease used to be rare, the chronic autoimmune disorder is becoming even more common. It comes about when eating gluten causes an immune reaction, resulting in diarrhea, bloating, gas, fatigue, or no symptoms at all.
Because of those symptoms, a 2016 study published in the journal Clinical and Translational Gastroenterology found many people get wrongfully diagnosed—especially due to everyone thinking poorly of gluten thanks to the gluten-free trend. Plenty of people end up being diagnosed without going through the whole process to ensure it’s actually a gluten sensitivity.
