What is hypothyroidism during pregnancy?

Changes in thyroid function are related closely to pregnancy. First of all, thyroid abnormalities can impact your fertility, making it difficult to get pregnant in the first place. Such abnormalities include hypothyroidism, meaning that thyroid activity is below normal; the thyroid gland is not releasing adequate amounts of the thyroid hormones triiodothyronine (T3) and thyroxine (T4), which decelerates your metabolism. If you do get pregnant, however, hypothyroidism impacts your pregnancy, but pregnancy impacts your hypothyroid condition. As pregnancy advances, there is an increased need for thyroid hormones, but there is a rise in pregnancy hormone, beta-human chorionic gonadotropin (ß-hCG). Peaking at the end of the first trimester, ß-hCG has a chemical structure similar to another hormone called thyroid-stimulating hormone (TSH), which comes from the pituitary gland in the brain and stimulates the thyroid when levels of T3 and T4 get too low. ß-hCG thus stimulates the thyroid as does the female hormone estrogen, which also rises during pregnancy. Consequently, if you are hypothyroid, but your thyroid is a little bit active, it’s possible that your condition might improve during pregnancy. However, due to the increased need for thyroid activity during pregnancy, it’s also possible that your condition will worsen or not change much at all.
