A thyroidectomy is an operation that involves the surgical removal of all or part of the thyroid gland. In general surgery, endocrine or head and neck surgeons often perform a thyroidectomy when a patient has thyroid cancer or some other condition of the thyroid gland (such as hyperthyroidism) or goiter. Other indications for surgery include ...
Side effects may occur from excessive doses. [2] This may include weight loss, fever, headache, anxiety, trouble sleeping, arrhythmias, and heart failure. [2] Use in pregnancy and breastfeeding is generally safe. [3] [2] Liothyronine was approved for medical use in 1956. [2] It is available as a generic medication. [3]
A large majority of the thyroid may be removed (subtotal thyroidectomy) to treat the hyperthyroidism of Graves' disease, or to remove a goiter that is unsightly or impinges on vital structures. [citation needed] A complete thyroidectomy of the entire thyroid, including associated lymph nodes, is the preferred treatment for thyroid cancer.
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] Typically, Free T 4 is the preferred test for hypothyroidism, [ 69 ] as Free T 3 immunoassay tests are less reliable at detecting low levels of thyroid hormone, [ 70 ] and they are more ...
It is a disease in which cells grow abnormally and have the potential to spread to other parts of the body. [8] [9] Symptoms can include swelling or a lump in the neck, difficulty swallowing or voice changes including hoarseness, or a feeling of something being in the throat due to mass effect from the tumor.

Medications are used to reverse the symptoms of extrapyramidal side effects caused by antipsychotics or other drugs, by either directly or indirectly increasing dopaminergic neurotransmission. The treatment varies by the type of the EPS, but may involve anticholinergic agents such as procyclidine, benztropine, diphenhydramine, and trihexyphenidyl.
Diagnostic tests in nuclear medicine exploit the way that the body handles substances differently when there is disease or pathology present. The radionuclide introduced into the body is often chemically bound to a complex that acts characteristically within the body; this is commonly known as a tracer. In the presence of disease, a tracer will ...
