I'm interested in viewpoints on if gluten sensitivity can be caused by something
other than celiac. My blood tests showed negative, I did not have a biopsy.
I certainly respond to a gf diet.

But, is it possible that something else causes my symptoms & responds to a gf diet?
e.g., parasite, lyme disease, yeast infection, bacteria overgrowth, candida, etc.

Insights into this issue appreciated.
