Iron supplement: Talk to your doctor about oral iron supplements. If that does not work, a large dose of iron can be given intravenously, in one shot to make up for all the deficit.

Finding the cause: For your low iron is as important as replacement. Treatment always includes addressing the possible cause that might not be apparent as continuous, recurrent blood loss is common, but sometimes iron absorption is involved as well.
