Can A Colonoscopy Diagnose Celiac?


glut'nfree

Recommended Posts

So a brief background on my husband:

-Plagued with anxiety issues since childhood.

-Prone to nose bleeds as a kid

-Developed tinnitus after working at a feed-mill (teenage years) in Alberta, Canada

-Surgery for fungal ball in sinuses 10 years ago (AFTER 5 rounds of antibiotics due to misdiagnosis of sinus infection).

-major headaches for approx. 10 years (didn't resolve after surgery - ENT thought they found it by accident and had nothing to do with his headaches).

-nummular ezcema?? I know this is not a sign of celiac but it's a type of exzema that both he and my son have.

-blood test showed low levels of calcium and B12

- We have three kids with digestive issues (one with chronic diarrhea, distended belly, hard to fall asleep, moody, long eyelashes and the other with Autism (resolved on Specific Carbohydrate Diet (SCD), which has no gluten, etc).

About a year ago, we all went on the SCD. My husband's issues did not resolve, but he seemed to "cope" better with it all. Then, my husband went OFF the SCD in June and all craziness broke loose. He began having anxiety 'attacks' which he's never had before and gut issues (which also occured when eating almonds). Then he went off the gluten, and the gut pain and attacks went away. Again, it happened the second time. We then went out to a restaurant where there was a language barrier and he decided to do it anyway, despite asking and the waitress saying it was okay. The next day and for a couple of days after that, he was just "checked out". Barely spoke and just couldn't "handle life". Mentioned his thoughts were hard to stop from racing.

Here's where I'm confused. We suspected gluten awhile ago. The blood tests came back negative for celiac but we wonder if he was eating enough gluten. After finding out our son had autism, we removed all gluten from our home. My husband managed to have some everyday but, I can't remember how much. So, I wonder if he really had enough for any test to be positive.

In addition to this, his GI specialist did a colonoscopy to diagnose whether or not he had celiac? He did say he managed to get into the small intestine. I don't know if he did a biopsy of the small or the large intestine but although the biopsy came back slightly damaged, the GI specialist said it was IBS and NOT celiac.

After eliminating gluten (which we plan to continue, although we're wondering to go through with another test unless it is agreed that a colonoscopy can, indeed, diagnose celiac), my husband is able to cope so well. He no longer feels like life is overwhelming (although he has his moments - whereas before it was the opposite). He no longer feels the need to be a workaholic and can simply "be" with us without "checking out". His headaches are also lessening more and more and we're both a bit confused.

I'm thrilled that things are getting better. And I don't necessarily care about whether or not he has some sort of diagnosis. But, as some of you may know, some people just aren't taking his illness seriously at all. It might also help our children and his father (as his father struggles with similar issues).

Anyways, I've rambled on long enough. Thanks if you made it this far!! Please someone help us make sense of this GI specialist as I heard you need an endoscopy.

Welcome!

The intestinal damage caused by celiac disease is to the villi that line the small intestine. A colonoscopy cannot detect that.

It is common to do an endoscopy at the same time if celiac is suspected. The preparation for a colonoscopy is a pain, but it is more than enough for the endoscopy, so there is no extra prep. A colonoscopy is prudent to ensure that there are no other issues besides celiac disease present.

But in cases where the patient is not eating gluten in quantity on a regular basis, test results for both blood and biopsy may be negative.

I was diagnosed in 2000 with major damage to the villi. Five years later, a repeat colonoscopy/endoscopy showed healthy villi. Because of my age, a colonoscopy every five years is indicated--I'm a bit overdue.

Really?? So, no matter what, a colonoscopy (even if the so-called GI "specialist" went IN to the small intestine and grabbed a biopsy) could not have tested for celiac? Why on Earth???...

Hi,

If they took biopsy samples from the small intestine then they must have done an endoscopy. An endoscopy is done by going through the mouth, vs a colonoscopy going through the nether end. It is good to do both at the same time, and it sounds like the GI did that.

The tests for celiac are not perfectly 100% accurate, so even if he got a negative he could still have celiac disease.

glut'nfree Newbie

Thanks for the reply. :) No, they *only* did a colonoscopy. They did not go through the mouth. Unless my husband's confused as to which way is up. Ha!

The GI specialist said they went through the large intestine and that he was "able" to reach the small intestine.

Not very much of it then :unsure: There are over 30 feet of small intestine and he may have got the 'tail' end ( :P sorry), but there's no way he could have seen very much of it, and the upper part is the most important end, i.e., the duodenum downwards. And you need to take five or six biopsies from different areas to have any chance of a positive result because the damage is not continuous but often rather just in certain areas. I would be extremely surprised if he was able to get far enough to get a proper result.

Ugh... how infuriating then. My husband specifically WENT to the GI Specialist to test for Celiac. I remember discussing with my husband about the endoscopy and feeling that the GI specialist should do one. The "specialist" insisted that he didn't need one to test for celiac. What a waste of precious time and possible side effects from a procedure that may not have told us anything. *sigh* So much for "specialist". :(

It sounds to me like you got your diagnosis by response to diet. It might harm your husband to eat enough gluten to get positive test results.

      If there were stains or particles on a drink can in an area that would either contact the drink or my lips, I would wash that can whether or not I had celiac disease.

      You are on the money, but I should also add that Italian, French and other countries research shows exactly what I have said. Our FDA is behind the ball when it comes to this research and I am hopeful that Kennedy can straighten this out soon, albeit he is giving the food companies too long to just remove food dyes from our foods when in fact they have to remove all that in order to sell for example, in the UK as they aren't allowed such things. The food companies and the cola companies have also changed their formulas to have just sugar in them instead of corn gluten aka high fructose corn syrup and corn starch in them. Misinformation here in America is a very dangerous thing. I also have been grain free for a long time now and at no time can I even have the smallest amount of corn gluten -I recently got glutened from a supplement that claimed to be grain free yet upon further research I found that it had erythritol (corn sugar) in it and that is what got me sick for 7 days straight. I am not hopeful to ever be able to add back into my diet any of the grain glutens, but perhaps those who were only gluten intolerant might be able to, but for me being celiac, I have no hope in that. Thank you for the article, I will add it to my collection of research as I am collecting everything I can find on this subject and posting it on X as well as other places.  I also don't use psuedo grains i.e. quinoa as that also reacts negatively with my gut, so I am 100% a cassava/tapioca/arrow root girl and that is my go to bread replacement. There are some new items made with chicpea/green peas that are sold as rice alternatives, i bought one to try but haven't yet. So food companies are getting creative, but like you said, I am fresh whole foods and don't buy many processed foods, I make my own cheese, ketchup, pickles, jams, etc.

      There were small spots (stains) on the drinking area at the top of the energy drinks can from the store that looked as the same color as milk — maybe oat milk (Hafermilch) or a wheat-based drink (Weizendrink), but I’m not sure what it was. There were also some particles that looked like either flour or dust, but not many. Could it have been a gluten-containing drink spilled onto the can or just regular small stains which I shouldn‘t worry about? Do you watch out for stuff like that or am I overthinking? Would it cause damage to a celiac?

      This is such an important discussion! While corn gluten (zein) is structurally different from wheat gluten, emerging research suggests some celiac and gluten-sensitive individuals may still react to it, whether due to cross-reactivity, inflammation, or other factors. For those with non-responsive celiac disease or ongoing symptoms, eliminating corn—especially processed derivatives like corn syrup—might be worth exploring under medical guidance. That said, corn’s broader health impact (GMOs, digestibility, nutritional profile) is a separate but valid concern. Like you mentioned, ‘gluten-free’ doesn’t automatically mean ‘healthy,’ and whole, unprocessed foods are often the safest bet. For those sensitive to corn, alternatives like quinoa, rice, or nutrient-dense starches (e.g., sweet potatoes) can help fill the gap. Always fascinating (and frustrating) how individualized this journey is—thanks for highlighting these nuances! Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal.

      I’m so sorry your little one is going through this. Celiac recovery can take time (sometimes months for gut healing), but the ongoing leg pain is concerning. Since his anemia was severe, have his doctors checked his other nutrient levels? Deficiencies in magnesium, vitamin D, or B12 could contribute to muscle/joint pain. A pediatric GI or rheumatologist might also explore if there’s concurrent inflammation or autoimmune involvement (like juvenile arthritis, which sometimes overlaps with celiac). Gentle massage, Epsom salt baths (for magnesium absorption), or low-impact activities like swimming could help ease discomfort while he heals. Keep advocating for him—you’re doing an amazing job!
