Can you tell the difference between Celiac and Intolerance


Nisha29

Recommended Posts

Hi, I’ve labelled myself as intolerant since the few test I can back negative. Recently I went on a delusion where I thought I was having problems with gluten due to exam stress. As a result I’m feeling very unwell at the moment. Can gluten intolerances be severe? I’ve experienced cramping and sore stomach aches constantly, always tired, loss of appetite (which is very unusual as I love food), dizziness and I think a swollen lymph nodes in one armpit. I have another doctors appointment but I’m a bit insecure wether I should ask them to do further testing.

Hello Nisha and welcome to the forum.

I wonder if you can tell us a bit more about the testing you have already had?  Were there tests blood tests, an endoscopy, etc?  Were you eating roughly two pieces of normal gluten containing bread or the equivalent up until the testing for about 6-8 weeks?

If you can tell us a bit more this it would be helpful.

Regarding exam stress, I know several people who have had gastric issues around the times of great exam stress but they weren't coeliacs so it could be partly down to stress that you have worsening symptoms - but then again, it might not, so I am glad you are going to see your doctor again.

The difference between gluten intolerance and coeliac disease is the latter condition means gluten causes actual damage to your small intestine known as villous blunting.   Testing allows doctors to tell the difference because otherwise the two conditions can be quite hard to tell apart.

Nisha, when you had the testing done, had you been trying to eat gluten free? As Christiana explained, going gluten free before celiac testing will invalidate the tests and may result in negative test values even if you do have celiac disease. I also would like to know exactly what tests were administered. Celiac disease diagnosis requires very specific tests to be run to check for antibodies in the blood produced by inflammation to the small bowel lining that ingesting gluten causes for those with celiac disease.

Do you have access to your test results in your medical record and can you post them here, along with reference ranges for what is negative and positive?

Also, many doctors are not very knowledgeable about gluten disorders like NCGS (Non Celiac Gluten Sensitivity) and celiac disease and do not inform their patients not to go gluten free in the weeks leading up to testing and they may not run enough tests to account for variable immune system responses.

NCGS can give quite severe reactions in some people and cause damage to other body systems besides the small bowel lining. Neurological problems are one of those.

I’ve not had much testing but a blood test where Serum creatinine was lower than normal. I’ve only just realised the other test I had was for something else. I’m going back to the doctor for further testing. I was undertaking the assumption they were for this out it seems they were normal blood tests and I was told not to stop eating gluten which I did. I think I forgot due to the stress. I do have a chance I have the genes for it since my grandad was diabetic.

I think I had been gluten free. I was under a lot of stress and forgot about it. I also checked my results and it looks like a normal blood test. I had another test but it doesn’t seem to be related to celiac. The only thing that came out low was Serum creatinine. I’m a bit worried about it being celiac since my Grandad had type 1 diabetes.

As Cristiana mentioned, the Mayo Clinic guidelines for a pretest gluten challenge for serum antibody testing are the daily consumption of two slices of wheat bread daily (or the gluten equivalent) for 6-8 weeks leading up to the test. If you are going for an endoscopy with biopsy then the same amount of gluten for at least two weeks leading up to the procedure.

Request: 1. Total IgA, 2. tTG-IGA and 3. Deamidated gliadin peptide (DGP IgA and IgG) if you decide to engage with the pretest gluten challenge and seek antibody testing.

Creatinine level is a measure of kidney function and would not be related to celiac disease or NCGS.

There is some statistical correlation between type 1 diabetes and celiac disease.

Thanks for the advice. I did search online and it said lower creatinine is found in celiac but I decided to play it off as inactivity and stress due to exams. I’ll make sure to ask for those test and see if I can put this to rest.

      I only notice recently every time I eat green beans the roof of my mouth gets slightly itchy and I get extreme dizziness.     I get shaky and sweaty and it last for an hour or two before it goes away. I’ve been allergy tested in the past for food allergens only two came back positive (both in the tree-nut family) nothing in the legumes.   (I do have a celiac disease diagnosis, the reason I was food allergy tested was because I ate a walnut and my lips swelled up)  I decided to test this out to be sure so I ate a couple of cooked green beans last night within 15 minutes I was spinning, my shirt drenched in sweat. My heart racing.   I’m not sure what this is, I do have issues with others vegetables  as my stomach doesn’t seem to tolerate them. Even when they’re cooked I just can’t digest them but they never made me as dizzy and sweaty as the green beans.    anyone else experience this?

      I have found that in addition to gluten, I am sensitive to inulin/chicory root fiber. I wondered why I had gastrointestinal symptoms after drinking a Chobani yogurt drink - much like being glutened. Happened at least twice before I figured out that it was that chicory root fiber additive. I do not react to ordinary dairy, yogurt, etc.  For the holidays, I will only be baking gluten-free treats. I got rid of all gluten-containing flours, mixes and pastas in my kitchen. Much easier to avoid cross-contamination that way!

      It's great to hear that your gluten-free journey has been going well overall, and it's smart to be a detective when a reaction occurs. Distinguishing between a gluten cross-contamination issue and a reaction to high fiber can be tricky, as symptoms can sometimes overlap. The sudden, intense, food poisoning-like hour you experienced does sound more consistent with a specific intolerance or contamination, as a high-fiber reaction typically involves more digestive discomfort like bloating or gas that lasts longer. Since the protein bar was the only new variable, it’s a strong suspect; it's worth checking if it contains ingredients like sugar alcohols (e.g., maltitol, sorbitol) or certain fibers (inulin/chicory root) that are notorious for causing acute digestive upset, even in gluten-free products. For your holiday baking, your plan is solid: bake the gluten-free items first, use entirely separate utensils and pans (not just washed), and consider color-coding tools to avoid mix-ups. Additionally, store your gluten-free flours and ingredients well away from any airborne wheat flour, which can stay in the air for hours and settle on surfaces. Keep listening to your body and introducing new packaged foods one at a time—it’s the best way to navigate and pinpoint triggers on your journey.
