Oral consumption of excess thyroid hormone tablets is possible (surreptitious use of thyroid hormone), as is the rare event of eating ground beef or pork contaminated with thyroid tissue, and thus thyroid hormones (termed hamburger thyrotoxicosis or alimentary thyrotoxicosis). [26] Pharmacy compounding errors may also be a cause. [27]
Hypersecretion causes gigantism in children and acromegaly in adults; hyposecretion in children causes pituitary dwarfism. Thyroid-stimulating hormone promotes normal development and activity of the thyroid gland. Thyrotropin-releasing hormone stimulates its release; negative feedback of thyroid hormone inhibits it.
Hyperthyroxinemia is a thyroid disease where the serum levels of thyroxine are higher than expected. [1] Thyroxine or tetraiodothyronine (T4) is produced by the thyroid gland. The term is sometimes used to refer to hyperthyroidism, but hyperthyroidism is a more general term. [2]
Endocrine disorders are often quite complex, involving a mixed picture of hyposecretion and hypersecretion because of the feedback mechanisms involved in the endocrine system. For example, most forms of hyperthyroidism are associated with an excess of thyroid hormone and a low level of thyroid stimulating hormone. [2]
Graves' disease is an autoimmune disorder, in which the body produces antibodies that are specific to a self-protein - the receptor for thyroid-stimulating hormone. (Antibodies to thyroglobulin and to the thyroid hormones T3 and T4 may also be produced.) These antibodies cause hyperthyroidism because they bind to the TSHr and chronically ...
Overproduction or underproduction of a pituitary hormone will affect the respective end-organ. For example, insufficient production (hyposecretion) of thyroid stimulating hormone (TSH) in the pituitary gland will cause hypothyroidism, while overproduction (hypersecretion) of TSH will cause hyperthyroidism. Thyroidisms caused by the pituitary ...
Thyroid disease is a medical condition that affects the function of the thyroid gland.The thyroid gland is located at the front of the neck and produces thyroid hormones [1] that travel through the blood to help regulate many other organs, meaning that it is an endocrine organ.
Autoimmune disease in which the thyroid gland is gradually destroyed. Infiltration of lymphocytes. Hypothyroidism: Diffuse and lobulated [8] Thyroid hormone replacement: Prevalence: 1 to 1.5 in a 1000: Remission with treatment Pituitary disease: Hypersecretion of thyroid stimulating hormone, almost always by a pituitary adenoma [9] Diffuse ...
