Insufficient thyroid hormone production is associated with infertility in people of childbearing age by interfering with ovulation. Low thyroid levels in pregnant people may increase the risk of miscarriage, premature delivery, anemia, postpartum hemorrhage, and pre-eclampsia, which is a condition that causes a significant rise in an expectant patient's blood pressure during the last three months of pregnancy.
Insufficient thyroid hormone after delivery is also an underlying cause of postpartum depression, which may bring feelings of inadequacy and extreme tiredness.
