Thyroid hormones

Thyroid hormones are produced by thyroid glands. T₃ and T₄ are thyroid hormones that are made up of iodine and tyrosine.^[1] Less intake of iodine results in less production of T₃ and T₄ which may lead to a medical condition called hypothyroidism. Greater production of thyroid hormones leads to hyperthyroidism.^[2]

The thyroid and its hormones regulate themselves in a self-limiting process called a negative feedback loop.

Function

Thyroid hormones control the metabolism of the body. They act to increase the production of proteins, basal metabolic rate and growth hormone.
