Iron deficiency anemia linked to pregnancy

Along with menstrual blood loss, pregnancy is one of the most common causes of iron deficiency anemia in women of childbearing age.1 It may develop during pregnancy because the volume of blood expands and the woman needs more iron to support her baby’s growth.2 Serum ferritin and hemoglobin values fall during pregnancy in some women to levels equating IDA.3 And, according to the Centers for Disease Control and Prevention (CDC), there is a 3-fold increase in anemia from the first through the third trimester.2

Blood loss during and immediately after delivery appears to be the most important cause of iron deficiency anemia after pregnancy,4 although fetal iron needs undoubtedly contribute.
