> To be clear, I pretty much ruled out celiac long ago, because my symptoms are not _that_ serious.
My symptoms were less than yours (constipation once in a while) but I am 100% confirmed celiac. I had positives on the anti-tissue transglutaminase IgG, IgA tests and endoscopy confirmed extensive damage consistent with years of celiac disease. You should rule out celiac disease with the IgG, IgA tests, followed by endoscopy if positive.
