<<Disclaimer: Verify this information before applying it to your situation.>> First of all, can anyone give any advice about feeling good on the gf diet for months and then having a period where your symptoms return for no apparent reason known to you? I was diagnosed (I guess kind of) in February, 1999. I am strict with the diet and do not know why all of a sudden I am feeling as I was before. Is there any bloodwork that can be done to see if I am ingesting gluten and don't know it? My doctors don't seem to know ANYTHING! Very frustrating. Second of all, does anyone know who I can send my biopsy slides to that could confirm that I really have this. When asked, the doctors respond that they cannot 100% say that I have CD. Is that because our lab techs and doctors are not very knowledgeable? Any advice would be appreciated!
