What is the best thyroid state for maternal mothers to avoid cretinism?

Cretinism, which refers to severe mental and physical developmental delays primarily caused by untreated congenital hypothyroidism, can be a serious consequence when adequate thyroid hormone levels are not maintained during pregnancy. The best thyroid state for pregnant women to avoid cretinism is a euthyroid state.

In a euthyroid state, the mother has normal thyroid hormone levels, which are crucial for the developing fetus, especially in the first trimester when the fetal thyroid is not yet fully functional. Sufficient thyroid hormones during this period are essential for proper brain development and overall fetal growth. If the mother is hypothyroid, there is a risk of insufficient thyroid hormones, which can lead to developmental issues, including cretinism. Conversely, hyperthyroidism, while it involves excess thyroid hormones, does not adequately support the fetal thyroid function needed to maintain healthy development.

Therefore, maintaining euthyroid status throughout pregnancy is vital for minimizing the risk of congenital hypothyroidism and ensuring optimal fetal health.
