Food Intolerant Celiacs - How Do They Know?

Recommended Posts

I'm hearing about celiacs being intolerant to food other than gluten. I think I understand the milk intolerance (the damage causes lactose intolerance, but can reverse after a gluten free diet and after the stomach has healed for say 6 mos or so?) but what about the other common ones?

Can these be identified by IgE (immediate allergy) or IgG (delayed reaction) blood tests?

Part of the reason I ask is that my four year old has classic celiac sypmtoms but since we've already taken him off gluten, we may never get a paper diagnosis. His IgG & IgE allergy tests show reaction to egg, soy, dairy (& a few others). Is this the reaction celiacs typically have? Might these other food allergies go away over time? How does this work? Or is he reacting to the proteins like Celiac Disease?

Thank you for your replies, as I'm confused about the allergy connection.

I think with an IgE reaction, it isn't going to go away at any point.

I haven't heard anyone with a casein intolerance (different than a lactose one) getting over it.

I've heard people say they could deal with substances they had problems with after eliminating gluten for awhile. But I don't know if they tested positive.

One other intolerance I've heard is common in celiacs is yeast. I did run across a study showing that the yeast antibodies went away for some after a strict gluten-free diet. This happened more with the younger patients. http://tinyurl.com/2ahtmk Notice that these weren't IgE, though. I haven't seen anything similar for other intolerances.

I don't know that the IgG tests are the ultimate word. People seem to react to things that they don't have antibodies to or don't react to things where they do have the antibodies.

You can always try IgA testing through Enterolab. Their tests are said to work for up to a year after going off gluten. They also test for yeast.

When I asked, Enterolab told me that all my IgA reactions were permanent.
