congenital hypothyroidism

n.
Deficiency of thyroid hormone at birth, usually as a result of improper development of the thyroid gland, a genetic disorder affecting hormone production, or iodine deficiency during pregnancy. If untreated, the condition leads to stunted growth, intellectual disability, and other health problems.

congenital hypothyroidism

Congenital myxedema, cretinism Hypothyroidism of neonatal onset, which occurs in 1/±7000 births, more commonly in ♀, characterized by mental and physical retardation due to inappropriate thyroid development or inadequate maternal intake of iodine during gestation. See Myxedema.

hypothyroidism

deficiency of thyroid gland activity, with underproduction of thyroxine, or the condition resulting from it. Common in adult dogs, particularly certain breeds, as a result of an idiopathic atrophy of the thyroid or a lymphocytic thyroiditis. Alopecia, weight gain, mental dullness, fatigue, cold intolerance, infertility and neurological deficits are seen. In food animals the syndrome is classical neonatal colloid goiter. See also goiter.

autoimmune hypothyroidism
see lymphocytic thyroiditis.
congenital hypothyroidism
results from congenital thyroid dysgenesis, defective hormone synthesis or severe iodine deficiency. There is dwarfism, macroglossia and mental dullness.
iatrogenic hypothyroidism
may follow treatment for hyperparathyroidism in cats.
juvenile hypothyroidism
congenital hypothyroidism (above).
primary hypothyroidism
that resulting from disease of the thyroid glands.
secondary hypothyroidism
caused by a deficiency of thyroid-stimulating hormone, usually as a result of a lesion in the pituitary gland.
tertiary hypothyroidism
caused by a lack of synthesis or release of thyrotropin releasing hormone.
