"Either way, such an immune response is never good for a person with Hashimoto’s or other autoimmune disease. The immune system is already imbalanced and overactive during an active autoimmune condition. A consistent immune reaction to a regular food in the diet only makes the immune system more volatile, further exacerbating the autoimmune condition.
This overall activation of the immune system creates inflammation and explains why symptoms of gluten sensitivity vary. For some the inflammation may target the joints, creating pain and swelling. For others skin rashes and skin disorders ensue. Many others suffer inflammation in the brain, resulting in brain fog, mood and anxiety disorders, or memory loss.
The list of inflammation-induced symptoms brought on by a gluten sensitivity goes on and depends upon the person’s genetic makeup. Needless to say such systemic inflammation also flares up an autoimmune condition.
Experience shows a gluten-free diet is a must
In my experience, most Hashimoto’s patients fall somewhere between gluten sensitivity and celiac disease. Nevertheless, almost all patients with Hashimoto’s improve on a strict gluten-free diet, even if they do not fit the established criteria of celiac disease. By strict I mean you are 100 percent gluten-free. Because the immune reaction to gluten has been shown to last up to six months after exposure, cheat days or occasionally eating gluten will derail the therapeutic benefits of a gluten-free diet."
