Is Cretinism due to a congenital lack of thyroid secretion?

Cretinism is indeed caused by a congenital lack of thyroid secretion, specifically during the developmental stages of a child. It is a condition that occurs when the thyroid gland fails to produce sufficient thyroid hormones, which are essential for regulating growth and metabolism in the body.

When the thyroid gland does not produce enough thyroid hormones, it can lead to a number of developmental abnormalities and health problems in a child, including stunted growth, intellectual disabilities, delayed puberty, and other physical and mental impairments. This is why early screening and treatment of thyroid deficiencies in newborns is crucial to prevent or minimize the effects of cretinism.

The term "cretinism" is now considered outdated and somewhat offensive, and the condition is more commonly referred to as congenital hypothyroidism.
