<<Disclaimer: Verify this information before applying it to your situation.>> Hi everyone. I noticed in the CSA guide that Tums are not recommended for celiacs who are not in good control as the calcium carbonate content can cause diahhrea. My doctor recommended them for me for a calcium supplement and I have been having stomach problems a lot lately and I am going to be checked out again by my gastro. doctor. I was wondering if any of you have had problems with Tums. I assume that they are GF, as the guide did not state that they weren't. The nurse at my gastro. doctor's ofc. also recommended them for me and scoffed when I told her what the guide said. If you remember my question on laxatives a few days ago, she's the one that recommended Citrucel and said to take "less" when I told her that it has a trace amt. of gluten in it. She also said that I may have colitis, but recommended no followup on that just come back in three months for a routine checkup. Does anyone else have colitis and what do you do for that? I have quite a few bowel movements, especially in the morning and my stomach has been very sick. Thanks. Karen from Central NY, USA
