<<Disclaimer: Verify this information before applying it to your situation.>> Dear Mal, It's about 5 am and I couldn't sleep so I'm checking out the email. I found your question about a "weak positive" interesting. I was diagnosed with cd this past March. My mother has had diarrhea for about the past two years when she had her gall bladder out. From information I've read gall bladder surgery is one of the things that can trigger cd. Her doctor, after finally performing blood tests, told her they were positive and she may have a "mild" case. Excuse me, but two years of diarrhea? Like you say, on important matters like this, why ask your doctor? She has a biopsy scheduled, I believe. You mention continuing problems while on a gf diet. I have had this experience too. Are you IgA deficient? You can have bacterial overgrowth in your bowels. I'm no expert, but I would definitely get a second opinion. I've found most GIs in the USA are not very educated when it comes to celiac disease. My second opinion was Dr. Joseph Murray in Iowa City. Maybe you could talk to someone else in your area who have been diagnosed cd (if you know of any) and find out what doctor they went to. Good luck. Lisa in Iowa
