I went gluten free when I got diagnosed with Gluten Sensitivity in 2005 (this was before I knew anything about
Lyme). My hormone balance improved as a result (no more painful monthly cramps/migraines).
Now, I'm sensitive to airborne gluten, so I have to stay completely away from all sources of gluten exposure.
Gluten sensitivity can cause neurological issues in addition to, or instead of, GI problems. See
http://theglutenfile.com/ for more info.
Anyway, being gluten-free did not make any of the Lyme-related stuff better for me...
And I did get a CDC-positive Lyme test not from IgeneX but from Mayo Clinic's lab (my local hospital sent it there; I had no idea it was getting done at Mayo until I got the printout of the results).
I also experience relief of "classic Lyme" migratory joint pain when I take abx, and this pain returns with a vengeance when I stop abx or when I am herxing (i.e., first starting abx, or making a dose change)...
It is easier for the whole household to be gluten-free. I'm lucky in that my Husband has been allergic to wheat since he was in high school, so he helped me to learn how to cook things without wheat/gluten.
Methylation is a key detox pathway in the liver. I believe those who herx more severely from even small doses of abx/herbs likely have methylation issues that need to be looked into. At least, this is my personal experience (a week of low dose japanese knotweed put me in the hospital fighting for my life).
