Common questions in this guide

What is congenital hypothyroidism?
Congenital hypothyroidism occurs when a baby is born with a missing, underdeveloped, or malfunctioning thyroid gland. Because it affects brain development, it requires prompt medical attention.
Can my baby live a normal life with congenital hypothyroidism?
Yes. With early diagnosis and consistent daily medication, babies with congenital hypothyroidism can grow and develop completely normally. The key is starting treatment right away to prevent developmental delays.
What is the standard treatment for congenital hypothyroidism?
The standard of care is daily levothyroxine therapy. This medication replaces the missing thyroid hormone and must be carefully crushed and mixed with safe liquids so your baby can swallow it.
Who should adjust my baby's thyroid medication dose?
Your pediatric endocrinologist or pediatrician will adjust the medication dose. Because your baby is growing rapidly, they will need regular blood tests and weight checks to ensure the medication level remains accurate.
