Hashimoto's Testing While Gluten-Free?


Irishgirl76

Recommended Posts

Irishgirl76 Apprentice

Hello,

I was diagnosed with Celiac just over a year ago. I have adopted a strict gluten-free (and grain-free) diet. I eat very clean, no processed foods, no soy, no dairy etc. yet I am still not feeling better. Very fatigued all the time. I am starting to suspect my thyroid. They checked my TSH when I was diagnosed and it was fine, but in my research I see that TSH is a poor test for Hashimoto's, and what they should be looking for is antibodies. My question is this: since Hashimoto's has a clear link to gluten sensitivity/Celiac, if I get tested for it now, will it come up negative since I have been gluten-free for a year? This week I took my cousin for Celiac testing, as she has many symptoms of Celiac. Come to find out she was diagnosed with Hashimoto's and Graves Disease as a child. So there is a family history. I have booked a doctor's appointment but would like to know what the odds are of a false negative.

Thanks so much!

Alissa

I was strictly gluten free for about two years when I got my hashimotos diagnoses .Being gluten free will not cause a false negative when being tested for hashimotos .

Irishgirl76 Apprentice

Thank you!!! I have been searching the Internet for 2 days. Lol

Irishgirl76 Apprentice

Are these the correct tests I should ask for?

TPOAb - Thyroid Peroxidase Antibodies

TgAb - Thyroglobulin Antibodies

Free-T3

Free-T4

Should I ask for Graves testing as well?

Thanks!!

Those tests will give you a good idea if it's graves too, but by the sounds of it, you seem to have more hypo symptoms rather than hyper.

 

You'll want your Free T4 and FreeT3 to be in the upper 50-75% range of your lab's normal reference range (ideally). Those antibody tests should basically be at zero.  You might as well get your TSH checked too; that should be close to a one. Make sure you get your results and don't accept "you're normal" as an answer. If your numbers are at the edges of the normal range, that can be a problem for people... it is for me.  LOL

 

Good luck.

yes those are the tests you will want to ask  your doc to run.

After being gluten free for almost 2 years my  testing results were;

TG AB was 36.94 normal range is <28.70

my TPO AB was 998.76 normal range being  < 10.10

Thank you both very much. That will be very helpful. My TSH results were 1.6.

Oh and I ALWAYS ask for test results, especially since my sister had her whole family tested for Celiac after I was dx'd and she was told her results were "fine". One year later her daughter had a SEVERE DH breakout, went back to the doc. He pulled up their bloodwork result and oops, 2 do the kids were actually positive.

Your TSH is not a good indicator of whether or not you have hashmoitos ,, but unfortunately most doc do JUST  a TSH and go no further . Ask for  the TG AB and the TPO AB  ( stomp your feet a bit if you have too  to get the testing you need :D)

Irishgirl76 Apprentice

Thank you. I have gotten very good at stomping my foot. :D I was the one who demanded Celiac testing and my daughter and I both came back positive. I have been right on a few other self-diagnoses as well (ie - my daughter's asperger's), so I think my doc has learned to listen to my instincts. Thank goodness!! :)

I was strictly gluten free for about two years when I got my hashimotos diagnoses .Being gluten free will not cause a false negative when being tested for hashimotos .

Then why do so many suggest going gluten-free to control Hashimoto's?

I just had to do my thyroid panels today because they are thinking I have Hypothyroidism, along with the Prolactinoma (pituitary tumor) and low cortisol, and I have been gluten free for almost a year now.

I've never heard that before.  Daughter has Hashimoto's.  Gluten used to be an issue for her but is not now.  She does not now and neger had celiac but an intolerance to it.

cahill Collaborator

I have seen it suggested but fail to  find any evidence to support the suggestion.that going gluten free will control hashimotos.

 

I have been STRICTLY gluten free for 3 1/2 years and my hashimotos still progresses.

 

The suggestion may come about  because so many celiacs ( an autoimmune disease )  also have hashimotos ( an autoimmune disease ) just as many of us also develop  diabetes (an autoimmune disease ) and other autoimmune diseases .

 

 

 ** on a side note ** I have found being grain free does help me manage my blood sugar levels.

This video is long but it explains how gluten affects autoimmunity (including thyroid).

Interesting... Would you mind posting your results here when you get them?

 While you are always dispense top notch advice on this forum, especially with regards to thyroid disease, I have to add a comment on thyroid antibody testing.  There is a range that is normal for antibodies and like Celiac antibody testing, you will be hard pressed to test for a zero, unless you have no thyroid problems at all.  The lab I use is normal for anything under 40.  You do want the number to be as low as possible but for anyone with Hashi's and huge antibody numbers at diagnosis, getting that number below what is considered normal is great and should be considered a success.  Mine were 1200 the year before I was diagnosed with celiac.  I had already been diagnosed with Hashi's 15 years prior.  Fast forward 8 years gluten-free, and my latest testing showed a 32...the lowest it's ever been.  At those levels, there is still some random activity but it's considered so low that it isn't a threat to your thyroid.

 

Things I have learned.....the gluten-free diet most definitely helped stop the attack on my thyroid.  I still have to take hormone replacement as I went so long undiagnosed for Celiac BUT my thyroid is much happier and stable now.  Being gluten-free will not affect thyroid testing at all, at least not for diagnostic purposes.  Turning things around can take many years so don't give up if you have been gluten-free for 3 years and there isn't much change.....it still may come.

 

The reasons for developing more AI diseases when you need to be gluten-free and aren't is mainly because your AI system does not just stop at destroying your small intestine.  If you go long enough, it turns on other body tissue and the thyroid and pancreas, plus the joints, are the ones that are largely attacked following the small intestine.  I have no idea why these are the favorites and neither does the medical profession but maybe that will be uncovered one day.  It's all about inflammation.

Thank you Gemini. I have read lots of anecdotal stories about people going gluten-free and their thyroid antibodies plummeting. I just want to be sure that if the tests come back negative that it means I do not have Hashimoto's. Not that I have just stopped producing antibodies because going gluten-free has calmed my immune system. Some people are saying this can happen in as little as 3-6 months of being gluten free.

The more I read, the more I realize I have many symptoms of both hypo and hyper (or Graves??) - including Mitral Valve Prolapse, which I was diagnosed with last year. I've read some studies that say as many as 40-50% of those with autoimmune thyroid disease have this! I have written down all of my symptoms and rush factors, along with what tests I should ask for, to show my GP. Any advice or suggestions would be welcome.

Thanks,

Alissa

About a year after I got diagnosed with celiac disease I was diagnosed with hashimoto's.  They tested my thyroid at the same time they gave me the celiac test and my thyroid was fine.  A year later all my thyroid tests were severly bad.  I think this is no coincidence.  In fact I've read there are proteins in your thyroid that are very similar to gluten.  It makes me wonder if when you remove gluten from your body, those antibodies you have go attack your thyroid.  I have no idea if it works like this, but just makes me wonder . . .

I've had several tpo tests after going gluten-free. They are all over the place. Once almost normal, once out of the ballpark, once somewhere in between.

Levels vary. If you come up negative perhaps ask to be retested later to be sure. I've never tested "normal", but it may not be impossible. Someday :)?

I've been dismayed at the lack of harded evidence for it, too. And it's becoming an automatic recommendation from just about everyone to try gluten-free...and for AT LEAST a year. Seems like it stems from the folks over at stopthethyroidmadness.com who report people finding lots of success with it?

Hashi's is so common with celiac anyway, and when you go gluten free and all that inflammation starts to subside, thyroid antibodies may go down....way, way down.  There isn't always hard evidence of stuff from the AMA because they tend to study diseases that get a lot of press or will kill your faster than Celiac will.  I find it best to talk to others and try what they try because following a gluten-free diet for a year to see if that might be the problem certainly does not hurt anyone and you might end up finding that you have a problem with gluten.  If you do the diet correctly, that is, by eating healthy.

 

The stopthethyroidmadness people know what works best and they know how to diagnose and treat hypothyroidism.....much better than the AMA.  The AMA does not recognize sub clinical thyroid disease or they won't treat elevated antibodies until they get really bad.  They test your TSH and that's their way of doing things.  NOT!

 This is common for Hashi's...it can be all over the map until you get it under control but you still can pop "bad" from time to time.  It is much harder work for me to control my thyroid than the Celiac.  More maintenance involved.My antibodies are continually stable or coming down but my T3/T4 can become wonky sometimes. Doesn't happen often but once in a while it'll dip low and I feel it.

 Thanks.  :)  You are right. I should say that your TPO Ab should be very low and closer to a zero than the upper end of the range. It really is the bigger picture when it comes to thyroid testing isn't it... I guess it's the same with celiac.

 

My TPO Ab was only tested once and it was considered "normal" at 33.8 with a range of 0-34. I just assumed it was "normal" because my thyroid was pretty burned out after untreated hypo symptoms for 15 years. My TSH was my only abnormal test at the time (14something?) and my T's were considered normal too although they had almost bottomed out. 7 months later I'm on 112mcg of synthroid, and I'm still hypo with low T's and a TSH that is "within range" at about a 5. I don't think my thyroid works much since I'm getting close to full replacement amounts of T4 (synthroid) for my size.

 

I too hope that as i get my celiac undercontrol, I'll have less inflammation and maybe my TPO ab will come down further and the attack on my thyroid will stop before my thyroid is completely killed off.

      EDIT: I did find a monthly Zoom meeting for Celiacs through the Celiac Disease Foundation, so I'll be able to talk with some other people on January 15. And I also found a Celiac Living podcast on Spotify made by a celiac. I feel a little bit better now and I am still hoping I will find some more personal connections in my area.

      Welcome to the celiac.com community, @mamaof7! It means for the one celiac disease antibody test that was ordered, she tested negative. However, other tests should have been ordered, especially for someone so young who would have an immature immune system where there would be a high probability of being IGA deficient.  The one test that was ordered was an IGA-based antibody test. It is not the only IGA antibody test for celiac disease that can be run. The most common one ordered by physicians is the TTG-IGA. Whenever IGA antibody tests are ordered, a "total IGA" test should be included to check for IGA deficiency. In the case of IGA deficiency, all other IGA tests results will be inaccurate. There is another category of celiac disease antibody tests that can be used in the case of IGA deficiency. They are known as IGG tests. I will attach an article that gives an overview of celiac disease antibody tests. All this to say, I would not trust the results of the testing you have had done and I would not rule out your daughter having celiac disease. I would seek further testing at some point but it would require your daughter to have been eating normal amounts of gluten for weeks/months in order for the testing to be valid. It is also possible she does not have celiac disease (aka, "gluten intolerance") but that she has NCGS (Non Celiac Gluten Sensitivity, or just "gluten sensitivity" for short) which is more common. The difference is that celiac disease is an autoimmune disorder that damages the lining of the small bowel whereas NCGS does not autoimmune in nature and does not damage the lining of the small bowel, though the two conditions share many of the same symptoms. We have testing to diagnose celiac disease but there are no tests for NCGS. To arrive at a diagnosis of NCGS, celiac disease must first be ruled out. A gluten free diet is the solution to both maladies.

      For reference, daughter is 18 mths old. Was having painful severe constipation with pale stool and blood also bloating (tight extended belly.) Liver and gallbladder are normal. Ultrasound was normal. Dr ordered celiac blood test. We took her off gluten after blood draw. She is sleeping better, no longer bloated and stools are still off color but not painful.    "GLIADIN (DEAMID) AB, IGA FLU Value  0.84 Reference Range: 0.00-4.99 No further celiac disease serology testing to be performed. INTERPRETIVE INFORMATION: Deamidated Gliadin Peptide (DGP) Ab, IgA A positive deamidated gliadin (DGP) IgA antibody result is associated with celiac disease but is not to be used as an initial screening test due to its low specificity and only occasional positivity in celiac disease patients who are negative for tissue transglutaminase (tTG) IgA antibody."   Anyone know what in the world this means. She isn't scheduled to see GI until late April.

      Hi Trent and Cristiana, thank you so much for taking the time out to reply to me.  My daughters GP requested bloods, they came back as showing a possibility of celiac disease, she advised me to continue feeding gluten as normal and wait on a hospital appointment. When we got that the doctor was quite annoyed that the gp hadn’t advised to go gluten free immediately as she explained that her numbers were so high that celiac disease was fairly evident. That doctor advised to switch to a gluten-free diet immediately which we did but she also got her bloods taken again that day as it made sense to double check considering she was maintaining a normal diet and they came back with a result of 128. The hospital doctor was so confident of celiac disease that she didn’t bother with any further testing. Cristiana, thank you for the information on the coeliac UK site however I am in the Rrpublic of Ireland so I’ll have to try to link in with supports there. I appreciate your replies I guess I’ll figure things as we go I just feel so bad for her, her skin is so sore around her mouth  and it looks bad at an age when looks are becoming important. Also her anxiety is affecting her sleep so I may have to look into some kind of therapy to help as I don’t think I am enough to help. thanks once again, it’s great to be able to reach out xx

      I have been feeling so lonely in this celiac disease journey (which I've only been on for over 4 months). I have one friend who is celiac, and she has been a great help to me. I got diagnosed at the beginning of October 2025, so I got hit with all the major food holidays. I think I navigated them well, but I did make a couple mistakes along the way regarding CC. I have been Googling "celiac support groups" for the last couple days and there is nothing in the Northern Illinois area. I might reach out to my GI and dietician, who are through NW Medicine, to see if there are any groups near me. I cannot join any social media groups because I deleted my FB and IG last year and I have no desire to have them back (although I almost made a FB because I'm desperate to connect with more celiacs). I'm glad I have this forum. I am praying God will lead me to more people to relate to. In my opinion, celiac disease is like the only food- related autoimmune disease and it's so isolating. Thanks for walking alongside of me! I'm glad I know how to help my body but it's still not easy to deal with.
