My daughter is anemic and is now getting two units of blood.  She has been anemic for several years what could be her problem.  She had three complete blood exchanges when she was born she is now 42 years old and has had anemia  off and on ever since.
Hi... you have not mentioned the diagnosis for which she underwent exchange transfusion immediately after she was born. Nevertheless, I think her present condition may or may not be related to her past history. To diagnose the cause of anemia she will need to undergo a blood examination which will give a clue to the diagnosis. This has to be further confirmed by a bone marrow test if needed. You need to consult a hematologist for this.
