Okay, ya ready? You have 3 possibilities here:
- celiac disease
- non-celiac gluten intolerance
- wheat allergy.
It gets complicated because many studies and scholarly texts use "celiac disease" and "gluten intolerance" interchangably...they're not the same thing.
Celiac is an autoimmune disease. Once you have one autoimmune (Hashi's), you're more prone to developing another (celiac). So, yes, there is a connection.
Celiac can be tested for...blood antibody test, just like Hashi's. However, though a positive celiac antibody test is considered adequate for a diagnosis of celiac, a negative test is inconclusive. Endoscopy and small intestine biopsy is necessary to rule it out. You can NOT be on a g/f diet during this testing as that can return a false negative.
Non-celiac gluten intolerance is not an autoimmune disease...it's just that...a sensitivity to gluten. If you feel better after removing gluten from your diet, then perhaps you are just intolerant. Of course, celiac must be ruled out first.
Wheat allergy presents like any other allergy...it's usually swift and definitive.
With any intolerance or allergy, the AMOUNT of the substance you are allergic to is a significant factor in the reaction. How much gluten (not even sure there is gluten in Synthroid) is there in that little, teeny pill? However, Tirosint has no fillers, except water, so if you're worried, do some research on that.
Sounds like you need to have some testing done to see exactly what's going on...
Urgh. More tests...:P Thanks for the feedback! ~MM
