So.. there are different antibodies.
You have IgA / IgD / IgE/ IgM which have a “permanent” learned response to certain substances. These are secreted through gut mucosa.
Then you have IgG1-4, which aren’t transported by gut mucosa and are a temporary response usually to a protein being somewhere that it shouldn’t, eg. in your blood. Once the protein isn’t seen for 4-8 weeks, your body stops producing those antibodies and you can reintroduce that food again.
IgG1 potentially finds its way into your bowels by “leaky gut” syndrome, bleeding / lesions, zonulin over-expression and various other methods.
If you have non-celiac gluten sensitivity, particularly if this is a new thing, it would be worth checking into your bowel health, eliminating gluten for a few months and then slowly reintroducing it. You may return to normal eating successfully.
