O Bloodtypes


Mrs. Smith

Recommended Posts

Mrs. Smith Explorer

My Dr. always says that Im an O bloodtype and that its associated with gluten intolerance/celiac. Is anyone else an O? I have read the book Eat Right for your Type and wheat is the main food for O's to avoid along with Oranges and Dairy which I cannot tolerate either. Do you think there is something to this? Should everyone with an O bloodtype be tested? Thoughts...

I'm an O- but I've never heard that theory before. Strangely enough, my daughter (don't know her type, but would be willing to bet it's O) is intolerant to both dairy and oranges.

I discount that theory - too many people with different bloodtypes are ciliac, and, I don't remember which type it was, but the main food for one was wheat and many ciliacs are that type! Not very good advice. Btw, I'm ab+ - anybody know what I should eat? And don't say WHEAT! haha

I'm an O and I thought the book was pretty spot-on.

I really don't think his theory makes sense from a pathophysiological standpoint. I don't see how adding a sugar to the protein, in the case of A and/or B antigens, would alter one's response to their diet so dramatically. If someone knows, please elaborate. :)

I'd just like to point out that you're going to have a sampling bias on this board.

Since the majority of people of European descent are type O Open Original Shared Link, and pretty much everyone on the board has issues with grain (gluten) and also dairy (at least initially), you'll get a lot of people saying "I'm type O, and I can't eat wheat".

I am also type O, and, no, I can't eat wheat, but dairy makes up a huge portion of my diet.

And oranges.

A review: Open Original Shared Link

I am type O and have both Celiac and DH. However none of my many doctors has suggested that blood type has any effect. Of course, I have learned that they aren't all completely up to speed on either problem. Nonetheless, I know people with both Celiac and DH who are other blood types so I tend to discount the blood type connection.

Book says type ab should avoid wheat! LOL! Oh and Corn. Lists Celiac Disease as an increased risk in this bloodtype.

Interesting thoughts. I dont know if I believe it, either. I just thought that it was pretty weird that I had the O+ blood and the book pretty much had it spot on. Then my Dr was all about it. He is pretty cool like that. He teaches nutrition and is hesitant to prescribe drugs which I like! He thinks most ailments (with some acceptions, of course) can be remedied or at least helped along by diet and lifestyle changes. We are always telling eachother about the newest health breakthroughs we hear about and since me (Im his 1st celiac patient) he has started testing patients with unexplained symptoms with celiac panel bloodtests. Its a start, hope more drs are.

It's bunk. Millions and millions bought this book and, of course, it was right on for a certain percentage of them, which then made it seem real. I'm an O but so are numerous friends (O is the most common) and none of them have celiac or problems with wheat.

I don't buy it. My husband is type O and has no apparent issues with gluten. I'm type B and can't have gluten, dairy or oranges (if I drink orange juice or eat an orange, my psoriasis flares). I think our bodies are a tad more complicated than to be easily explained by blood type.

My daughter and I are both A+ blood type. I am diagnosed celiac and we know she gets sick from gluten. We don't have any other intolerances.

I've read the book & I don't buy all of it! But I do believe that O blood is the oldest blood type & at the beginning there was not wheat or grains so we were always meat eaters. I'm O-,three family members O- & we all are celiac, father was A & I suspect he was not d'xd correctly & he was celiac as well. He presented with almost all the symptoms but passed before celiac was ever mentioned....

I know I feel better with lots of protein,less sugar & low carbs...

      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.

      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.

      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.

      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
