Iron deficiency anemia?

IDA: Lack of iron usually due to too much blood loss. At your age it is most likely due to menses.

Fe deficiency anemia: Occurs when fe intake is not adequate to meet the needs of the body for red cell production.. Indeed, it is not a diagnosis unto itself, but rather an indication of another problem to be discovered and corrected to avoid recurrence. Work with your doctor to address the cause of your fe deficiency state, and correct it as well as the fe deficiency state itself. Good luck.
