How common are endocrine disorders in pregnancy?
Excluding diabetes, thyroid disorders are the commonest endocrine problems seen in pregnancy. In about 2% of pregnancies the mother is hypothyroid (an underactive thyroid gland). Hyperthyroidism (an overactive thyroid gland) is less common, complicating 1-in-500 pregnancies. Other endocrine disorders, such as Addison’s disease, prolactinoma and phaeochromocytoma are very rare in pregnancy.
What effect will my endocrine disorder have on my pregnancy?
Underactive thyroid (hypothyroidism) does not have major implications for pregnancy provided it is well controlled. Most women will need to increase their dose of thyroid replacement medication early in pregnancy and, if treated appropriately, the risk overall is very low. With hyperthyroidism, there is a small (1-2% risk) of overactive thyroid in your baby which can lead to a high fetal heart rate, growth problems and premature labour.
Have you treated cases like mine before?
Yes, we are experienced in both underactive- and overactive-thyroid problems, including the different medications used for thyroid disease in pregnancy. We have also managed rarer endocrine abnormalities in pregnant women, including pituitary prolactinomas and Addison’s disease.
