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 rate , depression , and ...
Although thyroid extract was useful and usually effective, some patients continued to complain of fatigue, weight gain, or other symptoms. Dosing until the 1960s was often a matter of prolonged adjustment trials. [19] It was known that not all of the iodine content of thyroid extract was in the form of effective T4 and T3 and that actual ...
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 ...
Thyroid hormones, another early weight loss drug, also raised energy expenditure but ceased to be used for weight loss due to cardiac risks and other adverse effects. [18] Selective thyromimetics that work on the thyroid hormone receptor beta may be able to exert some of the beneficial thermogenic effects of thyroid hormones with fewer adverse ...
This can cause hypothyroidism by reducing the thyrotropic effects of TSH. 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]
More frequent bowel movements may occur, and diarrhea is common. Weight loss, sometimes significant, may occur despite a good appetite (though 10% of people with a hyperactive thyroid experience weight gain), vomiting may occur, and, for women, menstrual flow may lighten and menstrual periods may occur less often, or with longer cycles than usual.
The two thyroid hormones are Thyroxine (T 4) and Tri-iodothyronine (T 3). T 4 and T 3 can be measured by their total amount, or free amount. As the free amount reflects the amount available to body tissues, the most treatment-relevant measures for thyroid disorders are Free T 3 and Free T 4. [68]
