Constipation And Diarrhea in Post Diagnosis, Recovery & Treatment of Celiac Disease Posted July 5, 2014 · Report to Admin LOL, Not too much TMI at all !!! That's why we are all here!!!! I too, have the exact same problem. Its good to know that according to you all, I'm 'normal'. I was only diagnosed 2 weeks ago so I look forward to being "consistent" !!! (and healthy!!) I am severely anemic (which is how we found out that I had Celiac Disease) and need to take iron supplements but it gives me horrible liquid diarrhea!!!(TMI???) I was taking ferrous gluconate as its only 35mg, and supposedly easier on the digestive system, but now the doctor has me taking ferrous sulfate, which is 60mg......time will tell. Anyone else anemic?? What are you supplementing with?? Let's get our poop in a group!!! heehee from Canada.
