Thyroid Disease in Pregnancy
Thyroid hormone medicine for the treatment of hypothyroidism used before pregnancy should not be quitted taking by patients, and they consult with an endocrinologist, since not being normal of the mother’s thyroid hormones affects baby’s neuromotor (intelligence and neurological) development negatively. The daily iodine needs of a human are 150 micrograms. Women’s iodine needs increase during pregnancy and the postpartum period, and they need 250 micrograms per day. If this requirement cannot be met with nutrients, pregnant women should take iodine supplements. The way of taking iodine supplement varies depending on the health policies of countries. The two most important hormones produced by the body during pregnancy are human chorionic gonadotropin (HCG) and estrogen, and the increase of these hormones in the body affects the levels of thyroid hormone in the blood.
