<<Disclaimer: Verify this information before applying it to your situation.>> Thought I'd send to the whole list because I too have been on iron pre-diagnosis since I was frequently anemic. The doctors all told me it was constipating. When my first child was born I was very constipated and the doctor told me to go off all vitamins since I was getting too much iron. When my second child was born (the celiac) I almost hemorraghed to the point of transfusion. I never needed one but I had to take copius amounts of iron for the next 6 mths to get my levels back to normal. At this time I had no problem with consipation since I was probably so low in iron my system was not overloading. Anyway this was all prior to diagnosis and I have yet to have iron since being diagnosed 1.5 yrs ago. This is not medical advice but my own opinions.
