My son was just diagnosed with Celiac disease via full panel blood work up. I had previously suspected that he had a milk allergy (Celiac symptoms?), but it turns out that he has no other allergies. I read that many people with Celiac disease are also lactose intolerant. How do I know if my son is lactose intolerant? :huh: I want to be sure that I remove all irritants.

If your son's blood work was positive for celiac disease, his villi will be quite damaged at this point. The tips of the villi are supposed to produce lactase, the enzyme that helps us digest dairy. If there are no villi tips, you will have a lactose intolerance as a result.

That is why all people diagnosed with celiac disease should eliminate dairy for at least six months, giving the villi a chance to regenerate, before trying dairy again.

Thanks! There is so much to learn!!! I am very grateful for this great resource and all of the people who participate in this message board.

So its possible to recover from a dairy lactose problem ? Is it the same for dairy casein or is that life long like Celiac ?

Casein and whey are milk proteins that cause an allergic reaction if you are allergic to them. It is similar to other allergies, but if it's a food allergy your body tries to rid itself of the allergen by vomiting or diarrhea. Lactose intolerance exists when you lack the lactase enzyme, so your body cannot digest lactose, causing discomfort. Two different problems. If you are lactose intolerant then you must avoid classic dairy foods. If you are allergic to milk proteins, then your diet restrictions must be much more broad, similar to gluten!

Some Celiacs are "temporarily" (short term) lactose intolerance, until they heal. After this, they can re-introduce dairy and generally do well with it. Some can't handle dairy very well after being glutened.

Others are lactose intolerant permanently, just like there are people with LI who aren't Celiac.

Some people never have any problems at all.

Keeping a detailed food journal, along with the type of day/symptoms, can help.

I am currently on a self-imposed 2 week dairy free diet to try to figure out if I am dairy-intolerant. I was diagnosed with Celiac last June, and have found some but not complete improvement as a result of going gluten-free. The last post discussed a difference between simply not tolerating dairy, and having an intolerance to casein. Can anyone recommend how best to figure this out? I wish I had heard the recommendation to go dairy free at the same time I went gluten free - then I might not be going through this now. Thanks!

I would also like to inquire if casein or lactose will cause damage to the intestines similar to gluten, or just cause discomfort and symptoms.

I know that this has most likely been answered several times. <_<

Lisa:

I don't think that lactose causes damage (to my knowledge), just discomfort/symptoms when we don't have enough lactase.

Casein, I think I've heard that it hypothetically can, in some people. I don't think they know enough yet.

I have just completed this. And I can say it made a huge difference to me. I lost some excess weight and also had lots more energy. Then I ate a chocolate Easter Bunny. I had no symptoms that day( unlike Gluten) so assumed I was OK. Two days later I was hit with this crippling bowel pain, and fatigue and that lasted for 2 days. It looks like I am dairy intolerant ! But is it lactose or casein ? And will it be forever? The symptoms were different to a Glutening - but not nice.

I have been told that later I may be able to have small amounts of goats milk cheese. But it looks like I need to be dairy free at the moment.

Ursa,

You are a wealth of information! I didn't know that about the villi. When I had my endoscopy the pictures they took and the biopsy showed NO villi present. Completely damaged. No one said anything about the dairy and I eat cheese on a daily basis. Maybe that's why the D not improving. Maybe I should cut out the dairy for awhile. I'm gluten-free for 2months, should I wait and then try dairy free, what is your opinion? My dr. doesn't give me much in the way of answers.

thanks for any help

Some ways that dairy can be an issue:

  1. Temporary Lactose Intolerance - from villi damage, as the tips of the villi produce lactase (the enzyme produced by the human body) to break down lactose (the complex milk sugar); when the villi regrow, the ability to produce lactase reappears as well
  2. Genetic Lactose Intolerance - inherited, genetic lactose intolerance, and quite common in the world (causasians are the exception to the rule, really), where the body, after three or four years of age, slowly starts naturally producing less and less lactase; even caucausians find that, as they get into old age, they cannot tolerate as much milk, and their stomachs digest less lactose themselves, leaving more to be passed on to the intestines, where bacteria in the intestines break down the sugar, releasing gas as a metabolic by-product (and producing gas, bloating, and pressure-induced pain as sympotoms)
  3. Dairy Allergy - this is an allergy to the dairy proteins, usually casein (not as often whey) and usually primarily one of the subtypes of casein, which causes a standard IgE mediated allergic response, including possible rashes, itchiness, and - in very severe cases - anaphylaxis
  4. Casein Intolerance - an IgG mediated immune response, less well understood than the allergy, to the casein protein, that causes digestive complaints, very (very) rarely intestinal damage, and questionably systemic issues in people who are sensitive to it

Georgie, to test whether you're casein or lactose intolerant, take some lactaid, then drink some milk. If you're casein intolerant, it will make you ill ... if it's lactose, it won't. It won't be comfortable if you react, but at least you'll know whether you can take a lactaid next time you crave a chocolate bar! :P

I have heard that casein intolerance is permanent, but lactose intolerance can be temporary if it's due to the celiac damage.

Thanks Laura,

Lactose is the stuff in dairy that some people's bodies can't fully process/break down.

Lactase is the enzyme that breaks down the lactose. Hence, lactaid. Lactaid isn't medicine, but lactase supplements.

Thanks Laura and Tarnelberry...it is clearer. This is tough stuff to understand.

      Draft gluten-free ciders… can they be trusted ?

      By Rejoicephd · Posted

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      Tea Bags and Gluten

      By Scott Adams · Posted

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      Inconclusive results

      By Scott Adams · Posted

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.

      Medication

      By Scott Adams · Posted

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow
