I do have Hashimoto's but not Sjogren's disease. I do have Celiac disease. Both of these diseases can be related to Celiac.I also have dermatitis and irritable bowel symptoms. After getting off of gluten, bowel and dermatitis cleared up. Thyroid medication had to be changed...I didn't need as much!
We were tested by Enterolab, last year. My son was tested by an allergist (blood) and we were told he didn't have Celiac...Enterolab confirmed what we already intuitively knew with a stool test and genetic testing....two main Celiac genes and intestinal damage...Hmmmmm.
Better trust your intuition...something is up.
