I recently had a skin test to see if i was allergic to many food products including wheat,barley,oats and rye. The test was conducted by an allergist and included many pricks on my back. My rye/wheat/barley/oats skin tests came back neg-would a gluten intolerance and or possiblity of celiacs show up with this test? Or is the only sign ingesting gluten?

Gluten intolerance or celiac would not show up in a skin prick test because it's not an allergy. It's an autoimmune disease so you'd have to diagnose based on intestinal damage, blood test, stool test, or dietary response.

Skin testing tests for IgE reactions, which involve histamine (think hay fever, itchy eyes, watery eyes, runny nose, anaphylaxis). Intolerances (which I think is a dumb name, it still involves an immune reaction so *I* call it an allergy) are usually IgG reactions which can only be tested for with a blood test. IgG reactions are often delayed by a couple hours to several days. My son's eczema flares up 24-48 hours after ingesting the offending item. When they do celiac testing, they test IgG and IgA reactions via blood tests. I believe the IgA component is the auto-immune response, but I'm not 100% certain, so someone correct me if I'm wrong.

My ds never had skin tests, but blood IgE tests revealed no allergies, but he was blood IgG (RAST test) positive to wheat, dairy, soy, egg, and malt and once we removed all of those from his diet his skin was completely free of eczema. I had to really push for the IgG testing. The dr didn't think my insurance would cover it and said that is why he didn't order it even after I specifically asked for it. I told him I would pay (it was $10 per food, so we were looking at $70 for the panel, worth every penny) so he ordered it. Insurance ended up covering it! BTW he was 6 yo when I finally found the dr that would do the test. Prior to that the ped allergist we saw didn't really "believe" in IgG reactions I guess and the primary care docs/PA's/nurse practitioners were not well versed in allergies at all. He'd been seen for various food related issues (my diet since I was nursing and his once he started solids) since shortly after birth.

      Protein or fat?

      By Jsingh · Posted

      Hi,  I care for my seven year old daughter with Celiac. After watching her for months, I have figured out that she has problem with two kinds of fats- animal fat and cooking oils. It basically makes her intestine sore enough that she feels spasms when she is upset. It only happens on days when she has eaten more fat than her usual every day diet. (Her usual diet has chia seeds, flaxseeds, and avocado/ pumpkin seeds for fat and an occasional chicken breast.) I stopped using cooking oils last year, and when I reintroduced eggs and dairy, both of which I had held off for a few months thinking it was an issue of the protein like some Celiac patients habe mentioned to be the case, she has reacted in the same fashion as she does with excess fats. So now I wonder if her reaction to dairy and eggs is not really because of protein but fat.   I don't really have a question, just wondering if anyone finds this familiar and if it gets better with time.  Thank you.

      Frequent nausea after gluten-free diet

      By petitojou · Posted

      Thank you so much! I saw some tips around the forum to make a food diary and now that I know that the community also struggles with corn, egg and soy, the puzzle pieces came together! Just yesterday I tried eating eggs and yes, he’s guilty and charged. Those there are my 3 combo nausea troublemakers. I’m going to adjust my diet ☺️ Also thank you for the information about MCAS! I’m from South America and little it’s talked about it in here. It’s honestly such a game changer now for treatment and recovery. I know I’m free from SIBO and Candida since I’ve been tested for it, but I’m still going to make a endoscopy to test for H. Pylori and Eosinophilic esophagitis (EoE). Thank you again!! Have a blessed weekend 🤍

      Unusual bright yellow but odourless discharge

      Yes, I, too, have osteoporosis from years of malabsorption, too.  Thiamine and magnesium are what keep the calcium in place in the bones.  If one is low in magnesium, boron, selenium, zinc, copper, and other trace minerals, ones bone heath can suffer.  We need more than just calcium and Vitamin D for strong bones.  Riboflavin B 2, Folate B 9 and Pyridoxine B 6 also contribute to bone formation and strength.   Have you had your thyroid checked?  The thyroid is important to bone health as well.  The thyroid uses lots of thiamine, so a poorly functioning thyroid will affect bone heath.

      That sounds so very likely in my case! I will absolutely ask my doctor on my next bone check coming up in March... Thanks a lot!

      Calcium levels as measured in the blood can be quite deceiving as the body will rob calcium from the bones to meet demands for it by other bodily functions. Also, supplementing with calcium can be counterproductive as it tends to raise gut pH and decrease absorption. More often than not, the problem is poor absorption to begin with rather than deficiency of intake amounts in the diet. Calcium needs an acidic environment to be absorbed. This is why so many people on PPIs develop osteoporosis. The PPIs raise gut pH. And some people have high gut PH for other reasons. Low pH equates to a more acidic environment whereas high pH equates to a more basic (less acidic) environment.
