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 ...
Hyperthyroidism is much less common in dogs compared to cats. [67] Hyperthyroidism may be caused by a thyroid tumor. This may be a thyroid carcinoma. About 90% of carcinomas are very aggressive; they invade the surrounding tissues and metastasize (spread) to other tissues, particularly the lungs.
Certain medications can have the unintended side effect of affecting thyroid function. While some medications can lead to significant hypothyroidism or hyperthyroidism and those at risk will need to be carefully monitored, some medications may affect thyroid hormone lab tests without causing any symptoms or clinical changes, and may not require treatment.
Hyperthyroidism has unique effects in children on growth and pubertal development, e.g. causing epiphyseal maturation. In growing children, accelerated bone growth from hyperthyroidism can increase osteogenesis in the short term, but generally results in short-stature adults compared with the predicted heights. Pubertal development tends to be ...
Thyroid disorders include hyperthyroidism, hypothyroidism, thyroid inflammation (thyroiditis), thyroid enlargement , thyroid nodules, and thyroid cancer. Hyperthyroidism is characterized by excessive secretion of thyroid hormones: the most common cause is the autoimmune disorder Graves' disease.
The hyperthyroidism usually develops over 2 to 12 weeks following iodine administration. [ 2 ] In some ways the Jod-Basedow phenomenon is the opposite of two physiological compensation mechanisms, the Plummer effect and the Wolff–Chaikoff effect , which in normal persons and in persons with thyroid disease, suppress the thyroid hormone after ...

Thyroid hormones act on nearly every cell in the body. They act to increase the basal metabolic rate , affect protein synthesis , help regulate long bone growth (synergy with growth hormone ) and neural maturation, and increase the body's sensitivity to catecholamines (such as adrenaline ) by permissiveness .
