What can untreated hypothyroidism in pregnancy lead to?

Untreated hypothyroidism in pregnancy can indeed lead to a variety of complications, one of which is preeclampsia. Preeclampsia is characterized by high blood pressure and can affect both the mother and the fetus, leading to serious health issues if not managed appropriately.

Hypothyroidism affects the metabolic processes and can lead to vascular changes, which may increase the risk of developing hypertensive disorders such as preeclampsia. The deficiency in thyroid hormones can also result in endothelial dysfunction and altered placental blood flow, further complicating the pregnancy. Addressing hypothyroidism through proper management, including medication and monitoring, is crucial to reducing this risk and ensuring better outcomes for both mother and baby.

Other complications associated with untreated hypothyroidism can include growth restrictions in the fetus and preterm labor; however, preeclampsia is a significant concern linked specifically to the effects of uncontrolled thyroid hormone levels on the vascular system during pregnancy.
