Courtesy of Hyperthyroidism is the term for overactive tissue within the thyroid gland causing an overproduction of thyroid hormones (thyroxine or “T4″ and/or triiodothyronine or “T3″). Hyperthyroidism is thus a cause of thyrotoxicosis, the clinical condition of increased thyroid hormones in the blood. It is important to note that hyperthyroidism and thyrotoxicosis are not synonymous. For instance, thyrotoxicosis could instead be caused by ingestion of exogenous thyroid hormone or inflammation of the thyroid gland, causing it to release its stores of thyroid hormones. Thyroid hormone is important at a cellular level, affecting nearly every type of tissue in the body. Thyroid hormone functions as a controller of the pace of all of the processes in the body. This pace is called metabolism. If there is too much thyroid hormone, every function of the body tends to speed up. It is therefore not surprising that some of the symptoms of hyperthyroidism are nervousness, irritability, increased perspiration, heart racing, hand tremors, anxiety, difficulty sleeping, thinning of the skin, fine brittle hair, and muscular weakness—especially in the upper arms and thighs. More frequent bowel movements may occur, but diarrhea is uncommon. Weight loss, sometimes significant, despite a good appetite may occur, vomiting, and, for women, menstrual flow may lighten and menstrual periods may occur less often. Thyroid hormone is critical to normal function of cells. In excess, it both

THYROID GLAND, endocrine gland that is situated in the throat below the larynx (voice box); the thyroid secretes hormones vital to metabolism and growth. The gland consists of two oblong lobes lying on either side of the trachea (windpipe) and connected by a narrow band of tissue; in normal adults the thyroid gland weighs 10 to 15 grams (0.4 to 0.5 ounce). The lobes of the gland, as well as the band, consist of numerous tiny sacks called follicles. The shell of each follicle consists of a single layer of cells wrapped in a thin membrane, and each follicle is surrounded by many blood capillaries. The space inside the follicle is filled with a viscous fluid called colloid, which contains mostly thyroglobulin, the storage form of thyroid hormone. There are actually two thyroid hormones, thyroxine (T4, or tetraiodothyronine) and triiodothyronine (T3). Their structure is identical, except that thyroxine has four iodine atoms and triiodothyronine has three. Under normal conditions, the thyroid produces more thyroxine than triiodothyronine. The raw materials needed to form thyroid hormone are iodine and the amino acid tyrosine, both of which are normally found in a persons diet. The iodine is actively taken up from the plasma by thyroid cells, in which it is incorporated into tyrosine molecules within molecules of thyroglobulin. The two hormones are formed by condensation of two iodinated tyrosine molecules within the thyroglobulin, and the thyroglobulin and incorporated thyroid
