Hypothyroidism during pregnancy facts
- Hypothyroidism, wherein the thyroid gland produces an inadequate amount of thyroid hormone, is a common disorder particularly in women of childbearing age.
- Hypothyroidism of the mother during pregnancy may result in developmental delay in the child.
- Treatment of hypothyroidism requires thyroid hormone medication.
- There may be indications to start thyroid hormone therapy in women who are borderline in thyroid function and who are either pregnant or desiring pregnancy.
- The treatment goal of hypothyroidism in pregnancy is to maintain a thyroid hormone level within high normal range.
- Pregnant women who are on thyroid hormone should have blood testing frequently during pregnancy as requirements may change.
- Early studies found that children born to mothers with hypothyroidism during pregnancy had lower IQ and impaired psychomotor (mental and motor) development. If properly controlled, often by increasing the amount of thyroid hormone, women with hypothyroidism can have healthy, unaffected babies.
Thyroid disease is particularly common in women of child-bearing age. As a result, it is no surprise that thyroid disease may complicate the course of pregnancy. Frequency varies among different populations and different countries. While pregnancy itself is a natural state and not a "disease," thyroid disorders during pregnancy affect mother and baby. This article focuses specifically on hypothyroidism and pregnancy. After a general description of normal and abnormal thyroid function, recent data on long term consequences in children of mothers who had hypothyroidism during pregnancy will be reviewed.
