gluten-free For Only Three Weeks. Will Biopsy Still Show Accurate Results?

I have had severe abdominal pain for a couple months. So I tried gluten-free one day and two days later felt a change. I had blood work done about 10 days in and it showed positive for gluten intolerance. So the GI is now doing colonoscopy and endoscopy. I will be one day shy of 3 weeks gluten-free, with day 3 I have non gluten-free crackers. Other than that, gluten-free to the best of my knowledge. Can I still test positive for Celiacs if indeed I do have it? I have never eaten gluten-free in my life prior to these 3 weeks. I am imagining I still have plenty of gluten or damage to be seen in my system if that's the case.

I would love to hear back from people on this!!

P.S. I also rotate between constipation and loose bowels, I have the chicken skin arms they call it, borderline anemic, infertility issues.

If it were me, I would want to be sure I get an accurate biopsy result and start eating a little gluten everyday. The superficial damage can heal quickly. Sure, you might have enough damage to get an accurate result. Make sure he plans to take at least 6 biopsies to increase the chances that he finds some damage. The intestines are around 20 feet long and a biopsy is tiny.

While it is recommended to continue to be consuming gluten when you get tested, the inflammation is spotty and can come-and-go so even while you're eating gluten you can potentially get a false negative result.  However, I think a false negative is less likely if you're eating gluten.  In my case, my blood test came back positive and I stopped eating gluten right away.  My biopsy was 3 weeks later and it showed visible inflammation and the biopsy came back with moderate to severe villi damage.  But everyone is different and I think it really depends on the timing and getting lucky enough to catch it during a flare up.  But in general, the antibodies do not go away immediately and it is the antibodies that are causing the damage.  It can take months or even a year or two for all of the antibodies to die off.  On the other hand, many people see a very noticeable improvement in symptoms just a week or two into a gluten free diet, which would suggest that the inflammation in the intestine is likely already starting to improve - which would effect the outcome of the tests.

 

I hope I didn't confuse you even further... the short answer is that it depends.  Hopefully now you have an idea of what it can depend on...

      Issues before diagnosis

      I agree, it so often overlooked! I live in the UK and I have often wondered why doctors are so reluctant to at least exclude it - my thoughts are perhaps the particular tests are expensive for the NHS, so therefore saved for people with 'obvious' symptoms. I was diagnosed in 2013 and was told immediately that my parents, sibling and children should...

      Celiac Disease and Skin Disorders: Exploring a Genetic Connection

      Maybe they can attribute certain skin conditions to either being susceptible to getting Celiac......or the other way around....but I have to ask if certain people are prone to Celiac because of genetics and some people aren't. It's kind of the same thing as what came first.....the chicken or the egg.?

      My journey is it gluten or fiber?

      @xxnonamexx, There's labeling on those Trubar gluten free high fiber protein bars that say: "Manufactured in a facility that also processes peanuts, milk, soy, fish, WHEAT, sesame, and other tree nuts." You may want to avoid products made in shared facilities. If you are trying to add more fiber to your diet to ease constipation, considering...

      Welcome to celiac.com @sha1091a! Your experience is a very common one. Celiac disease is one the most underdiagnosed and misdiagnosed medical conditions out there. The reasons are numerous. One key one is that its symptoms mimic so many other diseases. Another is ignorance on the part of the medical community with regard to the range of symptoms that celiac...

      Celiac Disease Patients Face Higher Risk of Systemic Lupus

      What kind of practitioner did the blood test? Was this a medical doctor, a naturopathic doctor, a GI doc? I would certainly follow up with them and ask why they advised you not to eat red meat. I mean, it could be something like they, themselves, are a vegetarian and give that advice to everyone. Have you had an endoscopy with biopsy of the small bowel...

      I agree, it so often overlooked! I live in the UK and I have often wondered why doctors are so reluctant to at least exclude it - my thoughts are perhaps the particular tests are expensive for the NHS, so therefore saved for people with 'obvious' symptoms.  I was diagnosed in 2013 and was told immediately that my parents, sibling and children should be checked.  My parents' GP to this day has not put forward my father for testing, and my mother was never tested in her lifetime, despite the fact that they both have some interesting symptoms/family history that reflect they might have coeliac disease (Dad - extreme bloating, and his Mum clearly had autoimmune issues, albeit undiagnosed as such; Mum - osteoporosis, anxiety).  I am now my father' legal guardian and suspecting my parents may have forgotten to ask their GP for a test (which is entirely possible!) I put it to his last GP that he ought to be tested.  He looked at Dad's blood results and purely because he was not anemic said he wasn't a coeliac. (This was the same GP who said Dad didn't have dementia, when months before one of his colleagues suspected it and told me Dad must be diagnosed).  Hopefully as the awareness of Coeliac Disease spreads among the general public, people will be able to advocate for themselves.  It is hard because in the UK the NHS is very stretched, but the fallout from not being diagnosed in a timely fashion will only cost the NHS more money. Interestingly, a complete aside, I met someone recently whose son was diagnosed (I think she said he was 8).  At a recent birthday party with 8 guests, 4 boys out of the 8 had received diagnosis of Coeliac Disease, which is an astounding statistic  As far as I know, though, they had all had obvious gastric symptoms leading to their NHS diagnosis.  In my own case I had  acute onset anxiety, hypnopompic hallucinations (vivid hallucinations upon waking),  odd liver function, anxiety, headaches, ulcers and low iron but it wasn't until the gastric symptoms hit me that a GP thought to do coeliac testing, and my numbers were through the roof.  As @trents says, by the grace of God I was diagnosed, and the diet has pretty much dealt with most of those symptoms.  I have much to be grateful for.

You may want to avoid products made in shared facilities.   If you are trying to add more fiber to your diet to ease constipation, considering eating more leafy green vegetables and cruciferous vegetables.  Not only are these high in fiber, they also are good sources of magnesium.  Many newly diagnosed are low in magnesium and B vitamins and suffer with constipation.  Thiamine Vitamin B1 and magnesium work together.  Thiamine in the form Benfotiamine has been shown to improve intestinal health.  Thiamine and magnesium are important to gastrointestinal health and function.

      Welcome to celiac.com @sha1091a! Your experience is a very common one. Celiac disease is one the most underdiagnosed and misdiagnosed medical conditions out there. The reasons are numerous. One key one is that its symptoms mimic so many other diseases. Another is ignorance on the part of the medical community with regard to the range of symptoms that celiac disease can produce. Clinicians often are only looking for classic GI symptoms and are unaware of the many other subsystems in the body that can be damaged before classic GI symptoms manifest, if ever they do. Many celiacs are of the "silent" variety and have few if any GI symptoms while all along, damage is being done to their bodies. In my case, the original symptoms were elevated liver enzymes which I endured for 13 years before I was diagnosed with celiac disease. By the grace of God my liver was not destroyed. It is common for the onset of the disease to happen 10 years before you ever get a diagnosis. Thankfully, that is slowly changing as there has developed more awareness on the part of both the medical community and the public in the past 20 years or so. Blessings!

      Dizziness after eating green beans?

      By knitty kitty · Posted

      @EndlessSummer, You said you had an allergy to trees.  People with Birch Allergy can react to green beans (in the legume family) and other vegetables, as well as some fruits.  Look into Oral Allergy Syndrome which can occur at a higher rate in Celiac Disease.   Switching to a low histamine diet for a while can give your body time to rid itself of the extra histamine the body makes with Celiac disease and histamine consumed in the diet.   Vitamin C and the eight B vitamins are needed to help the body clear histamine.   Have you been checked for nutritional deficiencies?

      I found out the age of 68 that I am a celiac. When I was 16, I had my gallbladder removed when I was 24 I was put on a medication because I was told I had fibromyalgia.   going to Doctor’s over many years, not one of them thought to check me out for celiac disease. I am aware that it only started being tested by bloodwork I believe in the late 90s, but still I’m kind of confused why my gallbladder my joint pain flatulent that I complained of constantly was totally ignored. Is it not something that is taught to our medical system? It wasn’t a Doctor Who asked for the test to be done. I asked for it because of something I had read and my test came back positive. My number was quite high.Are there other people out here that had this kind of problems and they were ignored?
