What form of hypothyroidism in infants causes severely stunted growth?

Congenital hypothyroidism is the form of hypothyroidism in infants that can lead to severely stunted growth. This condition occurs when the thyroid gland is underdeveloped or absent at birth, resulting in insufficient production of thyroid hormones essential for normal growth and development. If not diagnosed and treated promptly, it can lead to significant developmental delays and physical growth deficiencies. Early screening and hormone replacement therapy are crucial for preventing these severe outcomes.
