Gluten Challenge - Accurate?

Hi!

 

I've been gluten-free for nearly 2 years - with the first 6ish months a learning experience about cross-contamination.  I've also been diagnosed with endometriosis, and allergies to casein and egg white (skin prick testing).  I'm considering doing a real a gluten-challenge and getting tested for celiac and I'm looking for advice/opinions.  I have an appointment with my (new) primary care doctor on Monday to talk about this, among other things.

 

Long story short - I suffered years with severe abdominal pain.  In a single year I had 6 ovarian cysts rupture, and I was finally surgically diagnosed with endometroisis in September 2011.  They removed the adhesions and scar tissue and about 80% of my pain was relieved - it was amazing!  

 

By the following September I was still having GI issues (soft stool, gas, abdominal pain, painful BM, etc.) that was originally attributed to the endo, so my old primary care doctor suggested I try going gluten-free to see if that helped.  Well, it did help - a lot, but not completely, so in February 2013 I was tested for food allergies and learned about the casein and egg allergy as well.  When it comes to my abdominal area, I'm a wreck, and it's really hard to figure out where the endo pain ends and the food allergies begin.

 

After eliminating all three - gluten, casein and egg completely from my diet I felt better than I knew I could feel.  I had no idea how sick I really was.  I had normal BM, almost no gas, it was wonderful!  After about 6 months of feeling awesome (with occasional cross contamination issues with the learning curve), I decided to do a small gluten challenge of my own.  I was hoping that it was just the casein and egg causing the problems and that maybe gluten wasn't so bad after all, so I ate a sandwich with regular (casein and egg free of course) wheat bread.  I felt okay immediately after, but within 24 hours I was doubled over in severe gas and abdominal pain that reminded me of the ruptured ovarian cysts I used to get.  So, I decided then that a real gluten challenge and eating like that every day for weeks was totally not worth it and decided to just be gluten-free.

 

Since then, I have had occasional bouts of severe gas and pain like I had with the sandwich, and each time I've been able to look back at the food I've eaten and find something that I ate where I didn't check a label closely enough that turned out to have gluten in it (like the bacon that had barley malt syrup in it for example, ugh!).

 

Now, over the past 6 months, my abdominal pain and GI symptoms are returning.  I honestly can't tell if it's endo or food allergy/intolerances or what - hence the appointment coming up.  I've been extra careful to avoid gluten and my allergens, so I don't think that's causing it but I'm back to thinking about doing the gluten challenge and getting a diagnosis.  I'm thinking now might be a good time because I'm already hurting again anyways, so why not?  My reason for wanting to rule out or in celiac are mainly because I'm tired of having to justify my gluten-free diet, but I do have things like colon cancer in my family so I want to know if I'm going to have an even greater risk of it than I would otherwise.  My current doctor doesn't seem to think it's necessary for me to be gluten-free, many of my friends and family think it's just a fad but I'd really like to know whether the occasional contamination is causing actual damage and risk.

 

I'm hesitant to do the challenge, not just because of the pain it will cause, but I'm also worried that after 2 years of being gluten-free that the test results may not be accurate.  I'm curious about diagnoses - false positives and false negatives after being gluten-free for so long and doing a challenge.

 

Does anyone have any information about celiac testing after being gluten free for so long?  Is it accurate enough to be worth it?

Have you tried doing antibody testing anyway to see what your levels are? There is one member here who got a positive result on a blood test after 3 years gluten free!

 

As far as the gluten challenge, keep in mind that you have to eat a lot of gluten to complete a gluten challenge. (1-2 slices of bread per day for 8-12 weeks) If your symptoms are severe, then it may not be worth it. I was hospitalized with neurological complications on day 10 of my gluten challenge. Though I wonder if I have celiac, it's not worth risking a stroke to nail down a diagnosis. Therefore I'm firmly in the "can't get tested" camp. Keep in mind that my complications are RARE. Most people who gluten challenge will not have those problems. 

 

But for my kids, the benefits of getting a DX (or not, but either way knowing what was going on and getting out of limboland) were so overwhelming that I made the decision to gluten challenge them. They have been doing their gluten challenges since July and are doing okay. I'm pretty certain that they will have no trouble completing a full 12 weeks on gluten.

 

Only you can decide for sure what the risk/benefit ratio for you is, when it comes to gluten challenges. 

 

However, keep in mind that if you decide to continue gluten free and forgo a DX, you have to assume that you have celiac and treat it as such with a 100% strict gluten free diet. No cross contamination and no cheating. I know that celiac is a definite possibility for me and I really, really don't want to suffer the complications of untreated celiac, so I just live like I have confirmed celiac. Then if science ever advances and I get a confirmed DX, I don't have to live in regret for having a lax approach to my diet and worry about health complications.

Why do you want the testing?  From your description you are either gluten sensitive or have Celiac.  Unless you need the official diagnosis for something at work or whatever, I would not do the challenge for testing.  There really is no point and why suffer for 2 months just to learn what you already know?

Thanks BlessedMommy!  That's really interesting that someone tested positive after being gluten free!  I plan to ask my doctor about testing and I'll ask him if I can have the antibody testing done first without the gluten challenge - I'm also going to ask about whether I can/should have the genetic test to rule out Celiac as well (I know it won't give me a diagnosis but it will at least tell me if it's even a possiblity or not).

 

And you're right about just assuming the worst and staying gluten free!  I have no intentions of going back to eating gluten full-time or cheating and I'm very nervous about how I'll react to a challenge and whether I can even stick it out for long enough to get results.  :(

 

SMRI - I want a diagnosis because I'm tired of not being taken seriously.  It seems like I'm treated (by doctors, pharmacists, family, friends, etc.) like my gluten-free requirement is just a preference and it's just all in my head because I can't say that I have a medical diagnosis of anything.  You're right that I know that I'm at the very least sensitive/intolerant, but I'm looking for some kind of medical documentation I can point to when talking to medical professionals about ingredients in meds, my diet/meal planning/nutritional needs, etc.  And family and friends.. well a diagnosis won't help me with anything other than being able to tell them the doctor agrees with me I guess.  :/

Hi Jen, about the gluten challenge.. Mostly GI recommend the Gluten challenge so they can see whether you have celiac disease or dont.. The 2 year diet doesnt matter , it takes like 2 weeks to go on the Gluten challenge and if u do have celiac disease, the tests will be positive , i know that the gluten challenge can be unconfortable since i have already taken it so.. I think thats the only way to answer your questions that are messing around in your had... Im looking forward into hearing the results . :)

" For a gluten challenge we recommend eating 1/2 slice of bread or a cracker each day for the duration of the challenge.

  • Prior to blood testing we recommend 12 weeks of eating gluten.
  • Prior to an endoscopic biopsy we recommend 2 weeks of eating gluten."

I disagree with the two week challenge being all it takes.  While it is true that the gluten challenge for the endoscopic biopsy usually only requires 2-4 weeks of gluten, if you have blood tests done most doctors will recommend 8-12 weeks of about 1-2 slices of bread per day.  If you are eating more gluten than that you may be able to do a shorter challenge (4-8 weeks) but it doesn't work for everyone.  If you test early and get a negative, you may want to retest after the 12 week gluten challenge to see if that changes anything.

 

If you do decide to do the gluten challenge, I wish you good luck!

I'm just learning about all of this.  I was tested at my doctor's office and yesterday when my doctor's office called and said I was not gluten intolerant, I  was blown away.  So I came online and found this thread.  The gluten challenge was new information to me.  When I learned I'd have to eat gluten food for 4-12 weeks.  I said no way.  My hubby was the one who insisted I do the blood test at my doctors.  But when he found out I'd have to go back on gluten for the gluten challenge to get the antibodies built up again..... he backed down.  He says as long as I stay gluten free and am not in pain that is good enough for him.  There is just no way I can go back on gluten.

Most celiacs will test as normal after eating gluten-free for weeks, months (usually), or years - that means we're treating ourselves correctly!  ;)

I've heard that before and that's exactly why I'm worried that doing a gluten challenge may not be conclusive.

 

Thanks to everyone for your responses!  I have a lot of great information to think about and to talk to my doctor about on Monday.  :)

I'm in the same predicament. People don't believe me. I would love to know if I have Celiac but am afraid to do the gluten challenge. I don't want to worry if cross contamination is hurting me but mostly I want to have a diagnosis so family and friends don't mock me and treat my problem:health with respect. It is all so frustrating. I'll be interested in hearing what your doctor says. Mine said to remain gluten free and is not encouraging the challenge.

My doctor said basically the same thing.  He doesn't recommend trying the gluten challenge because of the severity of my reaction to gluten. :(

 

While doing research, I found some news that a new Celiac test is being developed that only requires a 3 DAY gluten challenge.  It's still in research phase, but it's looking hopeful.  I'm keeping my fingers crossed for this test to prove to be accurate.  I wouldn't hesitate to do the challenge if I only had to do it for 3 days.  Here's info:

I'm also considering waiting for a few years for improved testing. I was quite encouraged by that report of the 3-day gluten challenge!

Thank you for sending me the link to this article. I am really excited to hear about this new test! I can do 3 days too. I just don't think I'm every going to make it through 3 months on gluten!

I think the 3-day test is only in the developmental stage, and it could be several years before it's actually available.

That would be a wonderful thing for so many people. I also hold out hopes that they will make an option that requires no gluten consumption at all. (but I suppose that those of us who can't eat gluten for any reason, kind of have our answer anyways)

Thanks for the link. I knew this information but was thinking it might still be worthwhile. I'm thinking I might just wait for the new test that will hopefully be available in a few years.

My blood test went from positive to negative after only two weeks being gluten free.  The doctor wanted me to do a challenge and then be re-tested.  He said the challenge needed to be 4-6 MONTHS long to be certain.  I was already feeling fantastic so I was skeptical about returning to my previous symptom-filled life for 6 months just to get an official diagnosis.  I already knew I would be gluten free regardless of the results.  I ended up starting the challenge but giving up after about a month.  The doctor did the endoscopy anyway and it came back negative.  Doesn't really matter, I went back to being gluten free and once again, the symptoms disappeared.  

 

My son, on the other hand, was still testing positive after 6 months of being gluten free.  

 

It is different for everyone.

 

What will you do differently if you get a positive or negative test result?  Sounds like you already know you should be gluten free.  How will an "official" diagnosis change anything. What happens if you test (falsely) negative?   The biopsy only confirms Celiac, it cannot rule it out.

4-6 months for a challenge? 

 

I thought that 3 months was enough.

 

I'm almost to the 3 month mark of challenge with DD and was going to take her in for bloodwork next week.

That is what the U of C recommends:

A gluten challenge is the period of time when gluten is added back into a person’s diet to assist in the diagnosis of celiac disease. Antibodies take time to build into the blood stream before they can be detected through blood analysis. For a gluten challenge we recommend eating 1/2 slice of bread or a cracker each day for the duration of the challenge.

  • Prior to blood testing we recommend 12 weeks of eating gluten.
  • Prior to an endoscopic biopsy we recommend 2 weeks of eating gluten.

I am new to this. I Have been learning a lot and just found out about the gluten challenge. Iam not going to do it. I know I have a problem with gluten and both celiac and gluten intolerance run in my family. But, just eating corn bread made with spelt was horrible and that was one meal. I can't live that way for a couple months.

I would like to know if it is celiac or gluten intolerance, but I don't think knowing for sure is worth all the pain.

I am just now learning how careful I need to be.

      Taken Seriously

      By Scott Adams · Posted

      Your post demonstrates the profound frustration and isolation that so many in the Celiac community feel, and I want to thank you for channeling that experience into advocacy. The medical gaslighting you endured for decades is an unacceptable and, sadly, a common story, and the fact that you now have to "school" your own GI specialist speaks volumes about the critical lack of consistent and updated education. Your idea to make Celiac Disease a reportable condition to public health authorities is a compelling and strategic one. This single action would force the system to formally acknowledge the prevalence and seriousness of the disease, creating a concrete dataset that could drive better research funding, shape medical school curricula, and validate the patient experience in a way that individual stories alone often cannot. It is an uphill battle, but contacting representatives, as you have done with Adam Gray, is exactly how change begins. By framing it as a public health necessity—a matter of patient safety and protection from misdiagnosis and neglect—you are building a powerful case. Your voice and your perseverance, forged through thirty years of struggle, are exactly what this community needs to ensure that no one else has to fight so hard just to be believed and properly cared for.

      Allergy medication: cetirizine by the HealthA2Z is it gluten free?

      By Scott Adams · Posted

      Navigating medication safety with Celiac disease can be incredibly stressful, especially when dealing with asthma and severe allergies on top of it. While I don't have personal experience with the HealthA2Z brand of cetirizine, your caution is absolutely warranted. The inactive ingredients in pills, known as excipients, are often where gluten can be hidden, and since the FDA does not require gluten-free labeling for prescription or over-the-counter drugs, the manufacturer's word is essential. The fact that you cannot get a clear answer from Allegiant Health is a significant red flag; a company that is confident its product is gluten-free will typically have a customer service protocol to answer that exact question. In situations like this, the safest course of action is to consider this product "guilty until proven innocent" and avoid it. A better alternative would be to ask your pharmacist or doctor to help you identify a major national brand of cetirizine (like Zyrtec) whose manufacturer has a verified, publicly stated gluten-free policy for that specific medication. It's not worth the risk to your health when reliable, verifiable options are almost certainly available to you. You can search this site for USA prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/

      Protein or fat?

      By Scott Adams · Posted

      What you're describing is indeed familiar to many in the Celiac community, especially in the early stages of healing. When the intestinal villi are damaged from Celiac disease, they struggle to properly digest and absorb fats, a condition known as bile acid malabsorption. This can cause exactly the kind of cramping and spasms you're seeing, as undigested fats can irritate the sensitive gut lining. It is highly plausible that her reactions to dairy and eggs are linked to their higher fat content rather than the proteins, especially since she tolerates lean chicken breast. The great news is that for many, this does improve with time. As her gut continues to heal on a strict gluten-free diet, her ability to produce the necessary enzymes and bile to break down fats should gradually return, allowing her to slowly tolerate a wider variety of foods. It's a slow process of healing, but your careful approach of focusing on low-fat, nutrient-dense foods like seeds and avocado is providing her system the best possible environment to recover. Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal. This article may be helpful: Thank you for sharing your story—it's a valuable insight for other parents navigating similar challenges.

      Diagnosed celiac for 1-2 months ago and everything makes me bloated.

      By Beverage · Posted

      I had a very rough month after diagnosis. No exaggeration, lost so much inflammatory weight, I looked like a bag of bones, underneath i had been literally starving to death. I did start feeling noticeably better after a month of very strict control of my kitchen and home. What are you eating for breakfast and lunch? I ignored my doc and ate oats, yes they were gluten free, but some brands are at the higher end of gluten free. Lots of celics can eat Bob's Red Mill gluten-free oats, but not me. I can now eat them, but they have to be grown and processed according to the "purity protocol" methods. I mail order them, Montana Gluten-Free brand. A food and symptoms and activities log can be helpful in tracking down issues. You might be totally aware, but I have to mention about the risk of airborne gluten. As the doc that diagnosed me warned . . Remember eyes, ears, nose, and mouth all lead to your stomach and intestines.  Are you getting any cross contamination? Airborne gluten? Any pets eating gluten (they eat it, lick themselves, you pet them...)? Any house remodeling? We live in an older home, always fixing something. I've gotten glutened from the dust from cutting into plaster walls, possibly also plywood (glues). The suggestions by many here on vitamin supplements also really helped me. I had some lingering allergies and asthma, which are now 99% gone. I was taking Albuterol inhaler every hour just to breathe, but thiamine in form of benfotiamine kicked that down to 1-2 times a day within a few days of starting it. Also, since cutting out inflammatory seed oils (canola, sunflower, grapeseed, etc) and cooking with real olive oil, avocado oil, ghee, and coconut oil, I have noticed even greater improvement overall and haven't used the inhaler in months! It takes time to weed out everything in your life that contains gluten, and it takes awhile to heal and rebuild your health. At first it's mentally exhausting, overwhelming, even obsessive, but it gets better and second nature.
