Which condition refers to the absence of the thyroid gland or a lack of T3/T4 hormone production?

The condition that refers to the absence of the thyroid gland or a lack of T3/T4 hormone production is known as cretinism. Cretinism is a severe form of hypothyroidism that occurs in infants and children due to insufficient thyroid hormone levels, which can be caused by the absence or dysfunction of the thyroid gland. This condition often leads to growth delays, intellectual disability, and other developmental issues if not treated early.

In contrast, myxedema is associated with severe hypothyroidism in adults and does not specifically denote the absence of the gland itself. Hyperthyroidism indicates an overproduction of thyroid hormones, and hypoparathyroidism pertains to insufficient parathyroid hormone, affecting calcium levels rather than thyroid hormone production. Therefore, cretinism stands out as the condition directly linked to a lack of T3/T4 hormone production or the absence of the thyroid gland.
