<<Disclaimer: Verify this information before applying it to your situation.>> Does anyone out there know anything about Giardia (parasite infection that damages the small intestine)? Is a person more susceptible to Giardia if the have "Sprue"???? I was diagnosed with CD last October and went on a GF diet -- the results of my first biopsy showed short and blunted villi and my 2nd biopsy a month ago showed normal villi. Since then my three daughters have undergone biopsies and they all have Giardia so we (family) all are being treated with an antibiotic for 10 days. Can Giardia respond to a GF diet and heal the villi without antibiotics??? All of my antiibody panels were normal, so bloodwork testing is not helping me conclude anything. Have any of you experienced this before. I'll be grateful for any information. Still have to fit a few more pieces to the puzzle??
