Hi, my 44y/o sister has had most of her large colon removed about 5yrs ago due to some inflamatory condition. Since then, she experiences chronic severe anemia and has to get iron infusions every 3 or so months. She is having severe reactions to the injections and must be medicated and kept in hospital overnight. Is this common, what causes the anemia, (drs. have no answers) and what might be a better way to treat this condition. My sister is a critical care nurse for 10yrs, alcoholic as well and her bowels move very rapidly, perhaps hindering better absorption of iron? I'm a nuclear med tech, with not much medical intuition. I live in Tallahassee, Fl. My sister is a new live in for 2yrs now, and I really don't have much faith in medical care here in this town. Any advice would be greatly appreciated. YYYY@YYYY
