Re: Non celiac gluten intolerance
So glad to hear that you are taking your health into your own hands! I have celiac and have been gluten free for 2 years. Prior to that I was in kidney failure and I also have IC (Interstitial Cystitis). IC, Celiac and Hoshimoto are all Auto-immune disease-- so it's likely that gluten free diet will help you either way.
Have you ever been tested for a simple wheat allergy? Some people have gluten intolerance and/or Celiac in combination with a Wheat Allergy.
A few things to remember about gluten:
1) The longer its out of your system, the more sensitive you will be
2.) the smallest speck of gluten can cause a reaction--- since you don't have celiac, of course it is not as detrimental to your health, but I bet after a while you will become so sensitive, that anything with gluten/contact with gluten will start to bother you.
3) Symptoms of gluten intolerance/problems tend to first be anxiety, mania, sleeplessness, irritability, mental health issues, fatigue, etc. The stomach stuff comes years and years later for a lot of people. Just because you didn't test positive and your endoscopy came back normal, doesn't exactly mean you don't have Celiac. I would definitely adhere to a more strict gluten free diet, especially given your thyroid condition. If you happen to eat something with gluten, you are the only person to gauge how sensitive or sick you feel.
Does that make sense?
I just posted a crazy-long post about gluten in the (Urinary, Kidney, bladder) Interstitial Cystitis section in a thread called: Elmiron. I have 2 posts that talk about Celiac and autoimmune. It's just my story/ experience, but you may find it helpful!
Good Luck (and remember that with every autoimmune issues, stress is the biggest factor in staying healthy!).
