<<Disclaimer: Verify this information before applying it to your situation.>> Dear Group Well I self diagnosed and went off gluten for 4 weeks(first mistake) and have felt alot better. Last week I had some gum and maybe something else with wheat in it and I have been constipated and tired for 5 days. Is this normal? I saw my Dr and she is sending me to a Dr who is interested in Celiac disease. I am to go back on gluten. So pain here I come. Does anyone have a ballpark figure on how long you must be off gluten to get a negative biopsy? My Dr won't do the antibody tests as they don't find them to be very accurate. Please pray for me that I won't have to suffer to long before the biopsy. Regards, Valerie, Nova Scotia
