Answer 1

The effect of maternal hypothyroidism on the baby’s brain development is not as clear. Untreated severe hypothyroidism in the mother can lead to impaired brain development in the baby. However, recent studies have suggested that subtle brain abnormalities may be present in children born to women who had mild untreated hypothyroidism during pregnancy. Testing eith Free T3 and Free T4 should be done on Day 3 along with TSH.
