I am glad you are seeing another doc. The only time I was ever hospitalized was for anemia and still did not get a blood transfusion. That would seem a last resort and risky, not routine as they seem to be doing to you! Lots of iron is also very irritating to your gut and might cause bleeding. Your treatment regimen is very unusual, especially for only mild irritation.
49 year old female attorney, diagnosed UC/pancolitis 1985, no surgery but much suffering.
Asacol/5ASA 6x400 mg maintenance for 20+ years; use prednisone & Rowasa for flares.
August 2008 sought care of naturopathic doctor. Food sensitivity test showed gluten, other intolerances; started diet without gluten, soy, dairy, tomato etc. Replete probiotic first, now Forte pills.
Achieved remission for the first time in many, many years!? Seemed so, but colonoscopy Oct. 6 proved not so, heavy inflammation in ascending colon & will be using Rowasa again. But I AM better.
