Joint research by three American universities indicates that postpartum iron deficiency can cause anxiety, stress, and depression. The study looked at 64 South African women who were mildly iron deficient ten weeks after childbirth. Half the group was given iron supplements. Women who received no treatment appeared bored and distant and were more likely to interrupt their baby’s play at inappropriate times. The study also found that their babies were less responsive and less involved with them. Iron deficiency is very common during pregnancy, particularly during the third trimester. If you are concerned that you may be anemic, consult your doctor, or your pharmacist, who can recommend an over-thecounter supplement.
