I read your post and can relate. I've been in a moderate flair for about 8 weeks - and am very weak.
My GI said my recent blood tests show a hemoglobin count of 9. I've been lower (7) , as I know many who have UC get very anemic, but 9 makes a grown, normally healthy guy, very tired.
My thought for you was, my GI doc has me on FERREX 150 FORTE, seems to be helping. It's a combo of Iron & B-12.

with all due respect, your hemo must have been dangerously low to get a transfusion. As scarey as some of the potential side effects are from my drugs, so much recent research has been done on blood transfusions, and no-blood fluids and meds are steadily being approved. There are volume expanders and drugs that increase red blood cell production. Blood transfusions hold serious potential complications to patients.
An MD friend, underwent serious surgery a few years back. She told her husband, if things went bad, she was not to receive blood, unless her RBC dropped to like 3. Being an MD, she was well aware of the risks.
