EVEN WITH MILD HYPOTHYROIDISM, pregnant women are at risk for severe preeclampsia, preterm delivery, and/or pregnancy loss.
Some studies show that mild untreated or undertreated hypothyroidism can lead to lower IQ levels in children.
A common issue is the lack of adjustment of thyroid hormone dosage in women already on this medication prior to pregnancy.
In pregnancy, the requirements of thyroid hormone increases. A diseased gland is unable to meet these requirements. Similarly, if you’re already on thyroid hormone (synthroid/levoxyl, etc.), your dose needs to be urgently adjusted to get your hormone levels to the range required in pregnancy.
