I am having RAST testing tomorrow. Having had IBS for 10 years and 3 days after going gluten-free I was fine, I am wondering something.

If my RAST test does NOT show allergy to wheat, does that confirm Celiac? Thanks, Karen

No, it just confirms that you don't have an allergic IgE response to wheat.

It does suggest an intolerance, at least, if you feel better on the diet.

Hi Karen--No, if the RAST dosen't show an allergy to wheat, that does not tell you anything regarding Celiac. Since Celiac Disease is an autoimmune disease and not an allergy, the only tests that will confirm it are the Celiac blood panel and/or the biopsy of the small intestine. It is possible to have Celiac *and* a wheat allergy--I was allergy-tested for foods recently and was negative to wheat--but have diagnosed Celiac.

Allergy testing does not pick up celiac. Celiac has its own panel that is done. I have a wheat allergy in addition to celiac so if you had a true allergy to wheat in addition then that would show up.

Thanks, but I already know I have at least a wheat intolerance. What I want to know is if the Allergy test is negative (and I don't have a wheat allergy) does that make the likelihood of celiac greater?

No, they aren't mutually exclusive. Celiac disease and wheat allergy aren't related. Celiac is an autoimmune disease like diabetes and a wheat allergy is well, an allergy. For example, a diabetic is intolerant to sugar and the body reacts to it, but the diabetic is not allergic to sugar. It's a poor analogy, but that's basically how it is with celiacs.

There are some people on here with both a wheat allergy and celiac, but most aren't allergic. There are plenty of people out there with a wheat allergy that aren't celiac, as well.

Maybe I am not communicating well.

If I am gluten intolerant (I am definitely) and it isn't allergy.....is it celiac?

I'm not communicating well either :)

You can be gluten intolerant without being celiac.

A wheat allergy doesn't usually cause the same symptoms as an intolerance. If your RAST test comes back negative (and they aren't *that* accurate anyway) all it means is that you aren't allergic to wheat and that you are either gluten intolerant or celiac.

To medically rule in celiac, you have to have celiac blood tests done and/or have the biopsy.

Basically, regardless of the outcome of the allergy test, you could be celiac.

I think I understand.

Wheat bothers you, if you test neg. for an allergy then you want to know if that means (or means it's more likely) that the reason it bothers you is that your are intolerant or have celiac.

I however don't know the answer. I can say if wheat bothers you, then you probably shouldn't eat it LOL but you already know that.

It is possible for wheat to bother you and not to be gluten intolerant (I have a friend who can't eat wheat but does fine on barley) I think the only real way to see if you have celiac is to take the blood test, and go from there. Sorry if I am not much help.

If wheat is causing you a problem and you are not allergic to wheat and you feel better not eating wheat, then you most likely are intolerant to it. The absence of an allergy does not fit the requirements for diagnosis of celiac. However, if you get sick when you eat it and you are not allergic to it, then it's pretty clear you are intolerant of it.

Same with gluten.

If you want a diagnosis, you have to do the testing before going gluten-free. If you are comfortable enough just knowing it makes you ill, then just stop eating it! You will find all types around here, those who are confirmed by biopsy to those who were responsive to diet and never had the test. You just need to figure out whether you personally need the diagnosis.

Personally, I have an autoimmune response to gluten. I had an inconclusive biopsy. Therefore, I am not technically celiac. In my opinion, if I had waited longer and continued to eat gluten, I believe I would have eventually had damage they could find. I consider finding damage to the villi to be a pretty progressed stage considering how sick I was without it (or maybe they just didn't find it) and considering how sick some here were when it was eventually discovered. Many people develop a lot of other problems by the time the doctor diagnosis celiac.

You can be allergic to wheat as well as gluten intolerant. You can be gluten intolerant and not allergic to wheat, or allergic to wheat and not gluten intolerant. I am allergic to wheat and oats as well as gluten intolerant. If I eat wheat I get hives, asthma, throat swelling, and then later stomach aches and bowel problems.

Oh boy, I guess that answers my question but not my problem.

I had IBS that got progressively worse over 10 years until I went gluten free, to the point where I became dehydrated and needed IV's. Three days after being gluten-free I had no IBS and have been fine since then. Unfortunately, I saw a Celiac specialist months after going gluten-free so it was too late to test for it. He agreed with me that I would have to remain gluten-free forever and that it didn't make sense to go back on gluten in order to be tested.

So I guess I will never really know. Thanks for your information!! Karen

a lot of people say that dietary response is the only way to go. My 3 year old has an official diagnosis (blood work and biopsy) my 4 year old (will be 5 in July) had inconclusive blood tests and pos. dietary response, and I had a pos. blood test and am just starting on the diet.

There are all kinds of celiacs, I don't have any problem saying that my 5 year old "has it" because looking at her blood tests, I don't see how they were "inconclusive" and since she got sick and then got better gluten free, I think it's safe to say she has a problem with gluten.

I think if you feel better that's great, and that's all anyone really needs to know.

but, that's just my own opinion.

Saw my PCP yesterday and asked for Rast testing. He wanted to know why. I told him I probably have celiac and he said, "yes but you haven't been diagnosed". (I have been seen by a Celiac specialist in Boston who told me I probably did and shouldn't go back on gluten for a challenge). I told him to just write down gluten intolerance if he wasn't comfortable with celiac dx and that many people who are gluten intolerant have problems with other foods. After shrugging his shoulders like he doubted it, he did order it, but then wrote "patient requested" so I will probably end up paying instead of insurance. Why is it necessary to fight healthcare providers as well as one's disease? (rhetorical question). Karen

errrrrrr :angry:

That makes me so mad. Doctors should realize that you know more about your body than they do. And if he is not a specialist you probably are more educated on your disease then he is. My sister is an RN and they taught her at school that the patient usually knows more abour their disease and their bodys than you do, so listen to them! I hate it when they act like know-it-alls. I went years with know-it-all doctors who would not test me for anything and insisted that my asthma, hives and eczema were not allergy related. Finally a smart doctor tested me and it turns out I am very allergic. Avoidance and immunotherapy have made my quality of life a lot better because of him. All these others docs would rather have me suffer an suffer and keep coming back to them, shelling out my money to treat the symptoms but not the cause. Don't let it phase you. If it comes back positive shove it in his face.

That is what I couldn't understand. I am suffering with CFS and gluten intolerance, am disabled and home-bound. What happened to Drs. being diagnosticians and finding out what is wrong?

Honestly, I haven't had positive intolerance tests, but I have had a positive allergy skin test. I consider this a minor thing, but it's generally what I tell people I have because they can understand it without a ton of explanation. I'm sure most of my problem is intolerance. I'm not about to eat wheat again with a confirmed allergy in order to test positive for an intolerance. I just decided not to get nitpicky. Either way I can't really eat wheat. My general doctor hasn't been very helpful, but my other specialists (allergist, dermatologist, psychiatrist) all acknowledge that the diet experiment should be enough evidence because it is a legitimate diagnostic tool.

I justed wanted to say that I am one of those people with Non-celiac Gluten intolerance. The antibody test was negative and the biopsy taken 1 month after I went gluten free was negative (except for lymphocyte agregates). I was positive for both DQ2 and DQ8 and when I don't eat it I am fine and when I eat it I am sick. If you feel better then just keep doing it. My gastroenterologist said I could eat it for a month and try again, but why get sick again. Do you need the diagnosis for any special purpose or just to feel sure? If it won't change your insurance, disability, or help you in any way then don't make yourself sick just to get the doctor on board with the fact that you can't tolerate gluten. My doctors were not really on board but the genetic testing and the elimination diet experience got them to list it as Non-Celiac Gluten intolerance. It isn't easy to stick to the diet, but it sure feels great to stick to the diet. Hope you continue to have good health with the diet. J.P.

      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.
