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. [1] This may include weight loss, fever, headache, anxiety, trouble sleeping, arrhythmias, and heart failure. [1] Use in pregnancy and breastfeeding is generally safe. [2] [1] Regular blood tests are recommended to verify the appropriateness of the dose being taken. [1]
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.
The major side effects of this class of drug include hypertension, nausea, diarrhea, some cardiac electrical abnormalities, and thrombotic or bleeding episodes. [ citation needed ] Vandetanib , trade name Caprelsa, was the first drug (April 2011) to be approved by US Food and Drug Administration (FDA) for treatment of late-stage (metastatic ...
Side effects of the antithyroid medications include a potentially fatal reduction in the level of white blood cells. Therapy with radioiodine is the most common treatment in the United States, while antithyroid drugs and/or thyroidectomy are used more often in Europe, Japan, and most of the rest of the world.
The effects of calcitonin are opposite those of the parathyroid hormone (PTH) produced in the parathyroid glands. However, calcitonin seems far less essential than PTH, since calcium metabolism remains clinically normal after removal of the thyroid ( thyroidectomy ), but not the parathyroid glands .
Side effects may include allergic reactions, headache, vomiting, and conjunctivitis. [4] [1] Long term use may result in trouble sleeping and depression. [4] It should not typically be used during pregnancy or breastfeeding. [4] Lugol's iodine is a liquid made up of two parts potassium iodide for every one part elemental iodine in water. [8]
Surgery (thyroidectomy to remove the whole thyroid or a part of it) is not extensively used because most common forms of hyperthyroidism are quite effectively treated by the radioactive iodine method, and because there is a risk of also removing the parathyroid glands, and of cutting the recurrent laryngeal nerve, making swallowing difficult ...
