Getting diagnosed

Hello all. I'm new to all this. Here's my problem. I suspect I might be coeliac or ncgs. I have been going  to the doctors for years with really bad indigestion, fatigue, joint pain etc. More recently chronic constipation and bloating which I have to take epsom salt for every day. I have had the blood test for coeliac and it came back negative. Had a blood test that came back with low vitamin D (doctor said it wasn't that low though) in my mind deficiency is deficiency. Beer absolutely plays havoc with me guts(really painful heartburn and stich) I had a gluten free beer and I was fine. I have cut gluten out all together for the last week and the indigestion seems to of gone but I'm still constipated. My questions are 1-Do people think all of this could still be coeliac despite the blood test 2- how long does it take to feel better after stopping gluten 3- how long can a biopsy (which I haven't been offered) still diagnose coeliac after cutting out gluten?

Welcome to the forum, Dale!

Yes, despite negative blood antibody tests, you still could have celiac disease. 20% of whites and 80% of blacks who test positive through biopsy have a negative tTG-IGA score. Can you be more specific about what antibody tests were run by the doctor? There are a number of tests that can be run to detect celiac disease but many doctors will only run the tTG-IGA. And if your total IGA is low it can generate false negatives. Here is a primer: https://celiac.org/about-celiac-disease/screening-and-diagnosis/screening/

The symptoms you describe could also be related to SIBO (Small Intestine Bacterial Overgrowth) or possibly histamine intolerance. And both of those conditions are common with celiac disease.

After cutting out gluten you should start to feel better within a few weeks to a few months. It can take two years or more for the villi that line the small bowel completely heal.

If you begin a gluten free diet within weeks or more before either serum antibody testing or biopsy it will invalidate the results. Both kinds of tests are designed to detect damage caused by inflammation in the lining of t he small bowel caused by gluten ingestion and if you stop gluten the inflammation subsides and healing of the villi begin. Stay on regular amounts of gluten (defined by the Mayo Clinic as being the daily consumption of two pieces of wheat bread or the gluten equivalent) until all testing is complete.

Thank you so much for your reply. I am having serious trouble even getting an appointment with the doctors let alone being believed when I get there. No follow up appointments when testing comes back negative so I have to go through the recurring nightmare of ring up at 8am pot luck appointments nonsense. I have seen 5 different doctors now in 2 months. Even if they do end up referring me for biopsy I am not confident it will be a short wait. I have been really ill and I don't know if I can keep making myself ill on purpose while the NHS sorts itself out. Is there any real benefit to getting officially diagnosed or should I just give up at the doctors and carry on gluten free. I'm in the uk by the way. And in answer to your question I'm pretty sure it was the tTG-IGA test you mentioned. It's hard even getting that sort of information out if them, they don't tell you anything 😕

Thank you so much for your help I will look into the other conditions you mentioned also.

Dale, I understand that in the UK there is some kind of government subsidy to help offset the extra cost of gluten free food if you have an official diagnosis of celiac disease. Other than that, the antidote is the same for both NCGS and celiac disease, namely, adopting a gluten free diet for life.

In Scotland, Wales and Northern Ireland you can get all sorts of gluten free food on prescription but for some reason in England you can only get bread and flour

      Gluten free thyroid medications

      By Scott Adams · Posted

      The pharmaceutical industry (including BIG PHARMA! 😉) is very good about cleaning procedures before different drugs might be made using the same machinery. I don't believe cross contamination would be something to worry about, otherwise people with serious allergies, for example to antibiotics, would have serious issues with prescriptions drugs.

      Thanks for sharing that site! Do you know if that site has any information about manufacturing/possible cross contact on it? I can't find it. When I have called manufacturers, most of them say they can't guarantee no cross contact in manufacturing (except Lannett, Mylan and possible Amneal, which aren't available near me).

      Possible cross-contamination – concerned about symptoms

      By Dora77 · Posted

      Hi everyone, I have celiac disease and I’m asymptomatic, which makes things more stressful because I don’t know when I’ve been glutened. That’s why I try to be really careful with cross-contamination. For almost a year, I’ve been having yellow/orange floating stools consistently. I’m not sure if it’s related to gluten exposure or something else going on. I’ve been trying to identify any possible mistakes in my routine. Today, I made myself some gluten-free bread with cheese. Normally, I’m very careful: I use one hand to handle the cheese packaging (which could be contaminated, since it’s from the supermarket and was probably sitting on a checkout belt that had flour residue), and the other hand to touch my gluten-free bread and plate. But today I accidentally touched the bread with the same hand I used to grab the cheese pack from the fridge. The fridge handle might also have traces of gluten since I live in a shared household where gluten is used. I’m worried this mistake could have contaminated my bread. There were no visible crumbs or flour, but I know even trace amounts can be a problem. Has anyone had similar experiences or symptoms from this level of contact? Could this kind of exposure be enough to trigger symptoms or cause intestinal damage? Thanks for reading.

      Lubriderm-gluten-free?

      By Mswena · Posted

      So eight days in a row of gluten on top of gluten on top of gluten, I just had to resort to the EpiPen. I wish I could post a picture because you wouldn’t believe how enormous my gut is! It makes my head look like a pinhead.Ahhhgggsahhhhh!!!! I have discovered that I have to read the ingredients when I use a product up that I’ve been able to use without getting a reaction, because they can change the ingredients and bam my toothpaste now has gluten!!! my doctor told me gluten free means it has 20 ppm which someone with a severe a celiac as I’ve got that thing there kills me. I try to find certified gluten-free in everything. I can’t eat any oats unless it’s Bob’s red mill certified gluten-free. Good luck everybody this autoimmune disease is wicked wicked
