my Husband who is 95 was diagnosed with Anemia after gastropexy and ileocecotomy. He is now on Iron Ferrous sulfate 325 mg twice a day. Does low hemoglobin cause weakness and confusion. our primary said his HGB and HCT are starting to trend upward. He has been on the Ferrous sulfate a week now. They will not transfuse now HCT is 25 now and HGB is now 7.5. I am very concerned. His legs are weak also. Please help!!!
