0.3–0.4% (USA) [ 8 ] Hypothyroidism (also called underactive thyroid, low thyroid or hypothyreosis) is a disorder of the endocrine system in which the thyroid gland does not produce enough thyroid hormones. [ 3 ] It can cause a number of symptoms, such as poor ability to tolerate cold, extreme fatigue, muscle aches, constipation, slow heart ...
Thyroid diseases are highly prevalent worldwide, [10] [11] [12] and treatment varies based on the disorder. Levothyroxine is the mainstay of treatment for people with hypothyroidism, [13] while people with hyperthyroidism caused by Graves' disease can be managed with iodine therapy, antithyroid medication, or surgical removal of the thyroid ...
Euthyroid sick syndrome (ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...
Hyperthyroidism is the condition that occurs due to excessive production of thyroid hormones by the thyroid gland. [ 3 ]Thyrotoxicosis is the condition that occurs due to excessive thyroid hormone of any cause and therefore includes hyperthyroidism. [ 3 ] Some, however, use the terms interchangeably. [ 5 ]
Levothyroxine, also known as L-thyroxine, is a synthetic form of the thyroid hormone thyroxine (T 4). [ 5 ][ 8 ] It is used to treat thyroid hormone deficiency (hypothyroidism), including a severe form known as myxedema coma. [ 5 ] It may also be used to treat and prevent certain types of thyroid tumors. [ 5 ]
Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis and Hashimoto's disease, is an autoimmune disease in which the thyroid gland is gradually destroyed. [1][6] A slightly broader term is autoimmune thyroiditis, identical other than that it is also used to describe a similar condition without a goiter. [7][8] Early on ...
Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine (T3) and thyroxine (T4). They are tyrosine -based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production of ...
They are found in Hashimoto's thyroiditis and Graves' disease and may be cause of fluctuation of thyroid function in the latter. During treatment of Graves' disease they may also become the predominant antibody, which can cause hypothyroidism. [2] [13] The clinical and physiological relevance of neutral antibodies remains unclear.
