Can A Colonoscopy Show Celiac?


Leslie-FL

Recommended Posts

Leslie-FL Rookie

I was never tested for Celiac because I felt so much better after going gluten-free that I couldn't bear the thought of going back to how I had felt before in order to have a test done. I am overdue, though, for my every-five-year colonoscopy (colon cancer runs in my family, so my doctor recommends having them done). I was wondering if there would be any films or anything like that on file from my last one, that maybe my doctor could use as comparison to check the status of the villi. Does anyone know if Celiac can be diagnosed this way, without having to go back on gluten? My last colonoscopy was probaby 8 years ago, long before I realized that my problem was gluten.

Celiac is classically diagnosed by flattening of the villi in the small intestines, scalloping and by biopsy. None of this can be viewed or sampled during a colonoscopy.

Anytime there is a strong history of digestive issues, it's wise to have annual testing of the colon. Testing of the large intestines can look for Crohn's Disease and other issues.

If I were in your shoes (and I know what I know now), if you feel better on the gluten free diet, I see no reason to return to gluten, testing or no testing.

No, a colonoscopy won't show anything celiac-related. If you're itching for a diagnosis at this point, your best bet is probably the gene test. You won't have to go back on gluten for it. Of course, you may or may not have the known celiac genes. If you don't, I'm guessing you still won't start eating gluten so it's probably not worth it.

EDIT: Actually, based on your joining date here, have you been gluten-free for less than a year? If so, enterolab can still do a stool test for gluten intolerance without you having to go back on gluten.

I think I read that Dr. Fine of enterolab had researched microscopic colitis for years and discovered that it really comes from gluten intolerance, and that is why he invented the Enterolab stool test for gluten sensitivity.

One would have to mail him or his nurse to get an answer.

The previous poster wrote that enterolab can detect the antigliadin antibodies is a stool test for a while after going gluten-free. But not celiac.

There migh be something about microscopic colitis and gluten on the enterolab website and in the patent application that is online somewhere.

I actually went gluten free in April of 2007, but it took me awhile to join the forums.

Thank you to everyone for your input. It's true that I'm less interested in a diagnosis than in going back on gluten to get one. lol. Too many years of feeling awful - don't want to go back to that. :-)

      You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/  When I looked this one up I didn't see any gluten ingredients.

      Your situation is actually more common than many realize, and while confusing, there are logical explanations for your test results. The key points are that your biopsy showing villous blunting and increased lymphocytes does indicate intestinal damage typically seen in celiac disease, despite your negative blood tests. This phenomenon is known as seronegative celiac disease, which affects about 10% of celiac patients. Your partial HLA-DQ2 genetic result doesn't rule out celiac either, as a small percentage of celiac patients don't have the complete genetic markers. The fact that you've responded so dramatically to a gluten-free diet is another strong indicator that this is likely celiac disease rather than NCGS, since NCGS doesn't usually cause intestinal damage. Your doctor might consider ordering additional tests like IgG-based celiac tests (tTG-IgG or DGP-IgG), or repeating the endoscopy after you've been gluten-free for a longer period to check for healing. Many celiac specialists would actually diagnose you with celiac disease based on your biopsy results combined with your positive response to the gluten-free diet, regardless of the blood test results. It may be worth consulting with a gastroenterologist who specializes in celiac disease for further evaluation. Your experience highlights why celiac disease can be so challenging to diagnose and why doctors need to look at the whole clinical picture rather than relying on any single test.

      Hi all, I have to have gum surgery tomorrow and was wondering if I should ask for this new drug, Journavx, instead of Vicodin.  I tried looking it up online and got, Not gluten free.  There is no gluten in the ingredients for this drug.  ????  Has anyone else had experience with Journavx?  Advice?   Many thanks, Charlotte

      Hi Faye,  Sorry I didn't see your post sooner.  I suffered from ataxia as well.  None of my drs. thought it was dairy.  They were wrong.  Turns out lactose intolerance was the cause.  Pancreas just isn't making the enzymes like it used to.  I now drink lactose free milk for the calcium and eat lactose free yogurt by Green Valley, when I can find it.  My ataxia problems vanished.  Hope this helps.

      This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.
