What is hyperthyroidism?

Hyperthyroidism (overactive thyroid) is when the thyroid gland produces excessive amounts of thyroid hormones. The opposite of hyperthyroidism is hypothyroidism (sluggish thyroid).

The thyroid gland, located at the base of the throat, has an influence on almost every metabolic process, helping cells get the energy and nutrients they need. Hyperthyroidism is when too much of the thyroid hormones are produced. The thyroid produces the hormone thyroxine (T4). Enzymes convert the T4 into an active form (T3) which controls your rate of metabolism.

Thyrotoxicosis when the levels of thyroid hormones T3 and T4 are too high. It can be caused by:

Hyperthyroidism is more common in women than men. Graves' disease is the most common cause of hyperthyroidism.

Test for thyroid function

A laboratory can test for your level of thyroxine, and level of thyroid stimulating hormone (TSH). TSH is produced by the brain to tell the thyroid to produce more thyroxine. Many doctors say a level of TSH below 5 is normal, but the American Association of Clinical Endocrinologists now considers more than 3 to be abnormal. Some practitioners even consider above 2.5 to be unhealthy.

Symptoms of hyperthyroidism

Thyroid hormones control the pace of all of the processes in the body (the metabolic rate). If there is too much thyroid hormone, every function of the body tends to speed up (ie fast metabolism).

A Thyroid storm is a life-threatening emergency that requires urgent care. This severe form of thyrotoxicosis is characterized by a rapid and often irregular heartbeat, high temperature, vomiting, diarrhoea, and mental agitation.

Causes of hyperthyroidism

Excess iodine is normally excreted in the urine. A few writers maintain that very high iodine consumption can cause hyperthyroidism, but I could not find any research to confirm this.
