I’ve written before about my own path to figuring out my gluten issues and it seems everyone has a diagnosis story like mine, though most are far more involved and long-lived, with the average person waiting 10 years for a proper CD or gluten sensitivity diagnosis. Just recently I read that another reason gluten issues are misdiagnosed is due to false negative blood tests~ if you have an IgA deficiency, the blood test for gluten reaction can come up negative even if it is positive. This is a big deal because: “Immunoglobulin A (IgA) deficiency is 10 to 15 times more common in patients with celiac disease (CD) than in healthy subjects.” That is a quote from Clinical and Vaccine Immunology. Another article on Food Matters gives further evidence of the link between IgA deficiency and food allergies and intolerances, such as:
“A significant number of allergic individuals have associated IgA deficiency, and there is evidence that IgA deficiency is linked to the development of gastrointestinal food hypersensitivity. (5)
Increased susceptibility to food allergies is now associated with IgA deficiency. (2,4)”
And, “IgA deficiency is much more common among those with celiac disease (gluten intolerance) than the general population.”
A very readable article on this issue can be found here: Gluten Intolerance & Celiac Disease.
Just something to know so you can advocate for yourself and your loved ones. You can also work on healing your intolerance by healing your digestive system. Here’s what worked for me.
