It sounds like celiac

I lost 30% of my weight in a year with out trying. After a ton of tests were done, all negative, it occurred to me, that I was diagnosed with celiac as a child, but a doctor a few years ago told me I did not have it. Before that, in my adult life, I have eaten very little gluten. But, when I continued to lose weight I started eating pastas, pastries and other things full of gluten trying to gain. The more I ate, the more I lost. Then one day it dawned on me, what if that doctor was wrong? I told my endocrinologist and she ordered a tt IgA. It came back 39.0. I am seeing a different GI dr. I also have the celiac genes. I was so physically ill when I saw her, I elected to just go on a strict gluten free diet. That was 4 months ago. I have gained back 15% of my weight and feel great. My tt IgA this time was <1 !  They can not say I have celiac, because I did not have an endoscopy. I am 73 yrs old. Should I chance gluten again and get the endoscopy? My PCP doesn’t believe I have celiac and rolls her eyes. She said the tt IgA  is not reliable. What do you think? Should I have the endoscopy to clarify?

Your PCP is not well informed. The tTG-IGA is a very reliable celiac blood antibody test. There are some other foods, medications and diseases that can cause elevated tTG-IGA but the chances of the elevated tTG-IGA count being due to some other cause than celiac disease is not very great. This is especially true given your symptoms, your genetic profile and the fact that you have improved on a gluten free diet.

Is there any particular reason you need an official diagnosis?

I am attaching an article which outlines the various antibody tests for celiac disease and their reliability:

Thank you. I just get tired of my PCP acting like I’m an idiot. My GI feels I have it, but cannot officially give me the diagnosis without an endoscopy. So, I’m officially gluten sensitive, without the endoscopy.

Well, you have some decisions to make. If you want an endoscopy, you must start the "gluten challenge" and daily eat the gluten equivalent of 4-6 slices of bread for several weeks.

If you are doing great on a gluten-free diet and see no reason to get a formal diagnosis of celiac disease, then it's perfectly fine for you to just stay gluten-free. 

In the Europe the current protocol for making a celiac disease diagnosis in children is if their tTg-IgA (tissue transglutaminase IgA) levels are 10 times or above the positive level for celiac disease.

According to the latest research, if the blood test results are at certain high levels that range between 5-10 times the reference range for a positive celiac disease diagnosis, it may not be necessary to confirm the results using an endoscopy/biopsy:

      Diagnosis and further testing Celiac

      By Redanafs · Posted

      Hi everyone. Back in 2022 I had blood work drawn for iga ext gliadin. Since then I’ve developed worse stomach issues and all other health issues. My doctor just said cut out gluten. He did no further testing. Please see my test results attached. I just need some direction cause I feel so ill and the stomach pain is becoming worse. Can this test show indications for other gastrointestinal diseases?

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.

      To evaluate the TTG antibody result we’d need to know the normal range for that lab.  Labs don’t all use the same units.  However, based on any normal ranges that I’ve seen and the listed result being greater than a number rather than a specific number, I’d say yes, that is high! Higher than the range where the test can give a quantitative result. You got good advice not to change your diet yet.  If you went gluten free your intestines would start to heal, confusing any further testing,

      By Bev in Milw · Posted

      Scott is correct….Thank you for catching that!      Direct link for info  of fillers.    http://www.glutenfreedrugs.com/Excipients.htm Link is on 2nd page  of www.glutenfreedrugs.com   Site was started by a pharmacist (or 2) maybe 15-20 yrs ago with LAST updated in  2017.  This makes it’s Drug List so old that it’s no longer relevant. Companies & contacts, along with suppliers &  sources would need to be referenced, same amount effort  as starting with current data on DailyMed      That being said, Excipient List is still be relevant since major changes to product labeling occurred prior ’17.           List is the dictionary that sources the ‘foreign-to-us’ terms used on pharmaceutical labels, terms we need to rule out gluten.    Note on DailyMed INFO— When you look for a specific drug on DailyMed, notice that nearly all of companies (brands/labels) are flagged as a ‘Repackager’… This would seem to suggest the actual ‘pills’ are being mass produced by a limited number of wholesaler suppliers (esp for older meds out of  patent protection.).      If so, multiple repackager-get  bulk shipments  from same supplier will all  be selling identical meds —same formula/fillers. Others repackager-could be switching suppliers  frequently based on cost, or runs both gluten-free & non- items on same lines.  No way to know  without contacting company.     While some I know have  searched pharmacies chasing a specific brand, long-term  solution is to find (or teach) pharmacy staff who’s willing help.    When I got 1st Rx ~8 years ago, I went to Walgreens & said I needed gluten-free.  Walked  out when pharmacist said  ‘How am I supposed  to know…’  (ar least he as honest… ). Walmart pharmacists down the block were ‘No problem!’—Once, they wouldn’t release my Rx, still waiting on gluten-free status from a new supplier. Re: Timeliness of DailyMed info?   A serendipitous conversation with cousin in Mi was unexpectedly reassuring.  She works in office of Perrigo, major products of OTC meds (was 1st to add gluten-free labels).  I TOTALLY lucked out when I asked about her job: “TODAY I trained a new full-time employee to make entries to Daily Med.’  Task had grown to hours a day, time she needed for tasks that couldn’t be delegated….We can only hope majorities of companies are as  conscientious!   For the Newbies…. SOLE  purpose of  fillers (possible gluten) in meds is to  hold the active ingredients together in a doseable form.  Drugs  given by injection or as IV are always gluten-free!  (Sometimes drs can do antibiotics w/ one-time injection rather than 7-10 days of  pills .) Liquid meds (typically for kids)—still read labels, but  could be an a simpler option for some products…
