After I get the endoscopy done, I’ll try to be in gluten-free diet even if I test negative for celiac disease or NCGS to avoid any complications. It does suck because I love wheat breads and Indian breads like rotis and naans, lol. I guess I have to jump to gluten-free options for those. Again, thanks for all your help.

@Jack Common, You could do a DNA test to see if you have any of the known genes for Celiac Disease.  If you don't have any genes for celiac disease, look to another source for your health problems.  If you do have celiac disease genes and have improvement on the gluten free diet, you probably have active Celiac.  Further testing would be beneficial. Keep in mind that different gluten containing breads have different amounts of gluten.  Think thick chewy pizza crust and artisan breads, and whole wheat breads for the gluten challenge.  Cookies and pastries do not contain as much gluten.   Since your blood tests were inconclusive, continuing with the gluten challenge may be needed to provoke a stronger autoimmune reaction sufficient for antibodies to get into the blood stream.      

I found out I had celiac because of eye problems. I developed an eye irritation that was sensitive to light, pressure, and red. My eye doctor said I had iritis, an inflammation of the iris. The treatment was prednisone drops. This is a common symptom related to ankylosing spondylitis, a form of arthritis that runs in my family. My doctor wanted to start me on immunosuppressants, but I refused due to side effects. I tried a few anti-inflammatory diets and found the specific carb diet helped, which led my doctor to test me for celiac, which was positive. Now I know when I get glutened because I have a flare up of my iritis. I call it my canary in a coal mine. First the eye, then the arthritis flare up begins.  

Soap, water and scrubbing won’t “kill” gluten, but it will physically remove it if done well if you also add a thorough rinse step.

Thank you for your help!
