I went gluten-free three years ago without any celiac testing at the recommendation of an (obviously ill-informed) doctor when I was experiencing severe GI distress with no known cause after the birth of our first son. My GI symptoms disappeared (until a few months ago, but more on that in a moment). I always just assumed I was gluten-intolerant and told people so, and I assumed that having celiac disease was very unlikely due to the low incidence rate. Additionally, I knew I'd have to consume gluten to get tested for celiac disease, and I wasn't willing to put myself through that. Then within the last six months I started having recurring GI problems again. I thought I was on a decent gluten-free diet so assumed that something else must be going on, such as a soy issue.
Last week an allergist requested to run the celiac tests on my blood, and I said ok despite telling him that I knew it would come back negative regardless of my disease status since I had been on a gluten-free diet for years. Shockingly, the DGP IgA came back positive.
My question is, should I just assume that I have celiac disease, or should I go through with a gluten challenge and getting an endoscopy? I get SO sick from consuming gluten, and as a result of last week's blood tests I've realized that I was obviously consuming hidden gluten and that it was likely the cause of my recent GI distress. However, I doubt it's been enough gluten to result in a positive biopsy. And I just can't imagine consuming large amounts of gluten for the biopsy considering how sick I've been lately with only consuming trace amounts of gluten. Prior to starting the gluten-free diet three years ago, I was having severe bloating and cramping and diarrhea 4 to 5 times per day alternated with days of constipation. I would imagine that my reaction would be even worse now that I've been (attempting) gluten-free for three years.
What are everyone's thoughts? Label myself as celiac or try to do a gluten challenge?
