Been Tested - Negative But... ?

I have done the blood work for Celiac - and it came back negative. But, somehow, I think that the results could be a false negative. I still continue to have diarrhea and soft stools (since early September) when I eat any sort of bread or crackers and no longer can eat cookies, pasta, oatmeal, potatoes, rice, etc. Now I know potatoes do not have gluten but it seems that once this all started, it was not just the gluten sensitivity that evolved but also a sensitivity to high fructose. I also have this skin problem(sort of dry spot that sometimes gets inflamed) on a small portion of my butt (had it for years but never really thought much of it until I read more about celiac symptoms). I had been diagnosed with IBS, but somehow, after this really bad bout of either a virus or food poisoning - the actual gluten/wheat intolerance and high fructose intolerance appeared. It almost seems as though that was the target for all these problems. Instead of IBS, could this have been celiac or wheat intolerance all along? I am now going to try going gluten free as well as avoiding high fructose as well.

Could the results of the blood work be wrong? Should I pursue this further or just try an avoidance diet first?

False negatives in both blood and biopsy are all too common so yes your blood test could be a false negative. If you are going to pursue further testing you need to keep eating gluten until it is done. You do have the option of doing a dietary trial, which is IMHO the best test there is, but if you decide later that you want to have the endo done you would need to do a gluten challenge for about 3 months. If you need to be gluten free that challenge can make you very ill.

I too have been told I have IBS. I really don't think IBS is a valid diagnosis. There has got to be some underlying condition cause your tummy to be upset. I had the bloodwork come back as negative too. I was told by my immunologist that the false negative rate is very high. He suggested I get and endoscopy and colonoscopy done. I had them done Monday 11/29 and am currently waiting for the biopsy results.

The dry skin patch you described sounds like eczema. I have had that since I was a baby. I get several patches of dry scaly skin, usually on my trunk or butt area. It is worse when the weather gets cold. Eczema can be a symptom of celiac disease.

Good luck on your search for an answer. You can try a gluten free diet to see if it helps, but if you are considering getting the endoscopy and colonoscopy, you should wait until afterwards. Not consuming gluten regularly can cause false results on the celiac biopsy if your intestines have begun to heal.

Tested negative here as well. As to potatoes, they are a night shade and can cause inflammatory problems with RA. My RA has responded positively to strict gluten free. I can't touch potatoes, though, without becoming immobile for days. I miss them. If you have the option of getting an endoscope done I would proceed. My GP ordered one in spite of the negative blood test in light of anecdotal evidence of reaction to gluten. Scope was positive. Make sure your GI doctor knows to sample from multiple sites if you get the scope done.

thanks for your answers. Funny, my gastroenteroloist thinks because my tests came back "normal" everything is okay. He is pushing for a colonoscopy without ever mentioning endoscopy. Now I do realize that an endoscopy is necessary but even that might not always show positive if I have not been ingesting gluten. I would hate to have to forgo all my hard work and have to make myself sick - and I am hoping my Gastroenterologist is more astute than he seems to be - I guess I should call him and talk to him...huh? He certainly has not given me any insight into how to solve my problem - he never suggested trying to stop eating gluten - his line was you need to be the detective. Are most gastroenterolists this detached or is this the norm?

In my experience, the doctors seem to want to test for everything else fist. It's as if they don't believe celiac exists, but they will diagnose you with IBS in a heartbeat :huh: You may have to stand up for yourself and really push the doc to do more testing. That's what I had to do. Good luck!

      Draft gluten-free ciders… can they be trusted ?

      Your suspicion is almost certainly correct, and you are wise to be cautious. Draft cider is a very common and often overlooked source of cross-contact because the same tap lines are frequently used for both beer and cider; unless a bar has a dedicated line for gluten-free beverages, which is rare, the cider will run through tubing that has previously contained...

      While it's always important to approach internal use of essential oils with caution and ideally under the guidance of a qualified professional, your experience highlights the potential of complementary approaches when traditional medicine falls short. Many in the community are also interested in the intersection of natural wellness and gluten-free living, particularly for managing systemic inflammation and its various symptoms, so sharing your story is valuable. Your observation that it may also be helping with bloating is fascinating, as that could point to an overall reduction in inflammation. Thank you for sharing what is working for you!

      Gluten and short-term memory.

      By Scott Adams · Posted

      It's interesting how a single, clear moment—like struggling during a game—can suddenly connect all the dots and reveal the hidden impact of gluten exposure. Your experience with short-term memory fog is a very real and documented symptom for many individuals with gluten sensitivity, often occurring alongside the other issues you mentioned like mood disturbances, sleep disruption, and digestive irregularity. It's a frustrating and often invisible effect that can make you feel unlike yourself, so that moment of clarity, though born from a tough dominoes match, is actually a powerful piece of self-knowledge. Identifying a specific culprit like that steak strip is a huge win, as it arms you with the information needed to avoid similar pitfalls in the future and protect your cognitive clarity. You are definitely not alone in experiencing this particular set of neurological and physical symptoms; it's a strong reminder of gluten's profound impact on the entire body, not just the digestive system. Supplementation may help you as well.  The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium.  Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend that those just diagnosed with celiac disease take a broad spectrum vitamin/mineral supplement, which would greatly benefit most, if not all, newly diagnosed celiacs. Because of this it took me decades to overcome a few long-standing issues I had that were associated with gluten ataxia, for example numbness and tingling in my feet, and muscle knots--especially in my shoulders an neck. Only long term extensive supplementation has helped me to resolve these issues.

      Reintroduction of Gluten

      By Scott Adams · Posted

      Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS. What you're describing is a very common and frustrating experience when reintroducing gluten after a period of avoidance, and your timeline is perfectly consistent with a non-celiac gluten sensitivity. While a celiac reaction can be more immediate, a sensitivity reaction is often delayed, sometimes taking several days to manifest as your body's inflammatory response builds up; the fact that your symptoms returned a few days after reintroduction is a strong indicator that gluten is indeed the culprit, not a coincidence. Your doctor's advice to reintroduce it was necessary to confirm the diagnosis, as the initial negative celiac test and subsequent improvement on a gluten-free diet pointed strongly towards sensitivity. Many in this community have gone through this exact same process of elimination and challenging, and it's wise to reintroduce gently as you did. Given your clear reaction, the best course of action is likely to resume a strict gluten-free diet, as managing a sensitivity is the primary way to control those debilitating symptoms and allow your body to heal fully.

      Your suspicion is almost certainly correct, and you are wise to be cautious. Draft cider is a very common and often overlooked source of cross-contact because the same tap lines are frequently used for both beer and cider; unless a bar has a dedicated line for gluten-free beverages, which is rare, the cider will run through tubing that has previously contained gluten-containing beer, contaminating your drink. The fact that you didn't react at a clean brewery suggests they may have had more meticulous practices or separate lines, but this is the exception, not the rule. Many in the community have had identical experiences, leading them to strictly avoid draft cider and opt for bottled or canned versions, which are poured directly from their sealed container and bypass the contaminated tap system entirely. Switching to bottles or cans is the safest strategy, and your plan to do so is a smart move to protect your health. PS - here are some articles on the topic:

      High Cost of Gluten-Free Foods

      By Scott Adams · Posted

      Your post really highlights the financial and emotional struggle so many families face. You are not alone in feeling frustrated by the high cost of gluten-free specialty items and the frustrating waste when your daughter can't tolerate them. A great place to start is by focusing on naturally gluten-free whole foods that are often more affordable and less processed, like rice, potatoes, beans, lentils, corn, eggs, and frozen fruits and vegetables—these are nutritional powerhouses that can form the basis of her meals. For the specialty items like bread and pasta, see if your local stores carry smaller, single-serving packages or allow returns if a product causes a reaction, as some companies understand this challenge. Regarding vitamins, that is an excellent next step; please ask her doctor to prescribe a high-quality gluten-free multivitamin, as insurance will often cover prescribed vitamins, making them much more affordable. Finally, connecting with a local celiac support group online can be a treasure trove of location-specific advice for finding the best and most affordable products in your area, saving you both time and money on the trial-and-error process.
