<<Disclaimer: Verify this information before applying it to your situation.>> I appreciate so many prompt replies to my question about whether undiagnosed celiacs always have anemia. Thirty people have responded that they (and sometimes several family members) were definitively diagnosed, but were NOT anemic. Several people also provided me with references to studies and surveys that have shown this is not uncommon. I asked the question because of something my new gastro doc said. My son was diagnosed with celiac seven years ago, but I have been having several issues lately that I am seeing the gastro about (lactose intolerance, diarrhea, mild weight loss). He is convinced I have IBS (in fact, that's what his nurse told me before he even saw me; my, my, aren't they efficient). I asked that he do the TTG test to rule out celiac first. He agreed reluctantly, but assured me that I couldn't POSSIBLY have CD, since blood tests taken by my primary care doc several months ago showed that I was not anemic. In this gastro's opinion women with undiagnosed celiac will be anemic 100% of the time (though he thinks men have a slight chance of not being anemic). Based on the responses I received, he is misinformed! We'll see about my case - we did the TTG test anyway. Tami in Minnesota, USA
