Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, Hashimoto's disease and autoimmune thyroiditis, is an autoimmune disease in which the thyroid gland is gradually destroyed. [7] [1] Early on, symptoms may not be noticed. [3] Over time, the thyroid may enlarge, forming a painless goiter. [3]
Hyperthyroidism has also been linked to an enlarged thyroid gland (goiter), irregular menstrual cycles, high blood pressure, brittle hair, and more prominent eyes, per Johns Hopkins Medicine.
In areas where iodine-deficiency is not found, the most common type of hypothyroidism is an autoimmune subtype called Hashimoto's thyroiditis, with a prevalence of 1-2%. [40] As for hyperthyroidism, Graves' disease , another autoimmune condition, is the most common type with a prevalence of 0.5% in males and 3% in females. [ 41 ]
People with hypothyroidism often have no or only mild symptoms. Numerous symptoms and signs are associated with hypothyroidism and can be related to the underlying cause, or a direct effect of not having enough thyroid hormones. [15] [16] Hashimoto's thyroiditis may present with the mass effect of a goiter (enlarged thyroid gland). [15]
The word "cretinism" is an old term for the state of mental and physical retardation resulting from untreated congenital hypothyroidism, usually due to iodine deficiency from birth because of low iodine levels in the soil and local food sources. The term, like so many other 19th century medical terms, acquired pejorative connotations as it ...
Congenital iodine deficiency syndrome (CIDS), also called cretinism, [2] is a medical condition present at birth marked by impaired physical and mental development, due to insufficient thyroid hormone production (hypothyroidism) often caused by insufficient dietary iodine during pregnancy.
Very few animals (e.g. axolotls and sloths) have impaired thyroid homeostasis that exhibits a very low set-point that is assumed to underlie the metabolic and ontogenetic anomalies of these animals. The pituitary gland secretes thyrotropin (TSH; Thyroid Stimulating Hormone) that stimulates the thyroid to secrete thyroxine (T4) and, to a lesser ...
The human body has a natural mechanism for regulating its normal core temperature: sweating. When your core temperature rises above its normal range — typically between 96.8°F to 99.5°F (36.0 ...
