I'm not yet convinced


NatalieCO

Recommended Posts

Hello everyone. Looking for some opinions! I'm 43f, overweight by 70lb, have had loose stools for many years now and many other symptoms that fit with Celiac, as well as other conditions, inc bloating, fatigue, lethargy at times, etc. Hashimoto's confirmed as teenager. 

I went to new GI in June to establish care to get routine colonoscopy due to family hx of colon cancer. The NP tested me for Celiac (surprised as none of my family have but somewhat limited info as my mom's parents died in their 40s and 60s and mostly estranged from dad's)

tTGa was weak positive at 8.03 (normal 0-5)

tTGg neg <0.82 (0-4.99)

IgA normal 189 (70-400)

Endoscopy showed mild lymphocytosis. No blunting or atrophy. Neg H pylori. Rare NSAID use. Report said unknown significance but possible treated or latent Celiac sprue or other cause. I have been eating a lot more carbs so tests would be accurate.

Stool culture negative.

GI said I likely have Celiac but I wanted more proof. Saw NP the other day who said since my tTGa was pos and lymphocytes present, then those 2 criteria say I have Celiac. She ordered more bloodwork per my request as I'm still not convinced:

TTGA normal 4.62 (0-4.99)

DGP IgA normal <0.72 (0-4.99)

DGP IgG normal 1.06 (0-4.99)

EMA and genetic tests are pending.

I'll do what I need to be healthy, but I'd like to know for sure before changing so much of my life and possibly seeing insurance rate increases with Celiac on my medical record... We have 4 young kids (2-12) so life is already quite busy!

I welcome any thoughts!

Welcome to the forum, @NatalieCO!

So, you have conflicting results from two different tTG-IGA tests, one at 8.03 and the other at 4.62, i.e. one a weal positive and the other a negative.

When they did the endoscopy, did they also biopsy the small bowel lining to have it checked microscopically by a lab for signs of the damage that would be caused by celiac disease's inflammation? 

You say you were eating lots of carbs at the time testing was done. Did that include plenty of wheat products?

If not celiac, you could have NCGS (Non Celiac Gluten Sensitivity). NCGS shares many of the same symptoms of celiac disease but does not damage the lining of the small bowel as does celiac disease. There is no test for it. It is 10x more common than celiac disease. Some experts feel it can be a precursor to the development of celiac disease. Eliminating gluten from your life is the antidote for both.

NatalieCO Newbie

Thanks so much for the response!

Yes the endoscopy had multiple samples taken of the duodenum which showed 'mild duodenal intraepithelial lymphocytosis with preservation of the villous structure.' The NP told me this shows damage consistent with Celiac but the histology report says there could be other causes inc H. pylori, Nsaid use, infection (all ruled out) and autoimmune disease (I have Hashimoto's). That's why I'm not yet convinced it is Celiac

And yes by lots of carbs, I do mean lots of gluten containing products

trents Grand Master

Celiac disease is an autoimmune disorder. Hashimotos would not affect the villous lining of the small bowel. So, all things considered, it makes me wonder if you are on the cusp of celiac disease. 

I think you are at the point where you need to trial a gluten free diet for a few months and see if some of your symptoms improve. You have had both the blood testing and the endoscopy done so there is no concern about invalidating testing by trialing the gluten free diet.

I don't believe in the "weak positive" classification--it is a positive test, and your immune system is likely reacting to gluten in an abnormal way. 

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.

Just to point out Hashimoto is also an autoimmune disease like Celiac so you most likely have very low 25(OH)D vitamin D blood plasma.  Low vitamin D plasma is is a compromised immune system and leaves you open to more autoimmune diseases in the future not to mention osteoporosis.

Personally, although the experts deny that osteoporosis is autoimmune, it makes sense to me that it is the first one to be affected by low vitamin D, then comes Hashimoto, Celiac and the rest.  Vitamin D at 80 ng/ml keeps the immune system from out of control B and T cells.

This article may clarify your test results and your resistance.

Are You Confused About Your Celiac Disease Lab Results?

 

NatalieCO Newbie

Thank you all for the helpful comments and articles! I am highly considering going gluten free just to see if I would feel better overall, whether or not I get an official diagnosis of Celiac.

And EMA just came back negative!

Genetic test results hopefully within the next week.

I assume you know that having one or more of the "celiac genes" does not equate to having celiac disease. Almost 40% of the population has one or more of the genes but only about 1% will develop active celiac disease. It's more of a rule out diagnostic measure in the sense that if you don't have one or more of the genes associated with celiac disease it is very unlikely you can develop celiac disease.

NatalieCO Newbie

Yes, I am aware having the 1 or more of the Celiac genes does not mean I would necessarily get the disease but I do appreciate the reminder.

My hope was just to rule Celiac out if I do not have the gene(s) and show the initial positive ttga was likely due to something else.

trents Grand Master

Don't forget about NCGS.

NatalieCO Newbie

So, DQ2.5 was detected (DQ2 heterozygous)

trents Grand Master

DQ2 has the strongest single gene association with the development of active celiac disease. DQ8 is next. Having both is even stronger and having homozygous celaic genes is also stronger.

      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!

      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.

      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:

      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.
