Thyroid dysfunction has afemale to male predominance a ratio of five to one. and the disease is increased in age. A family history of thyroid disorder is common in affected patients. Thyroid hormone regulates cellular metabolism, facilities development of the central nervous system, and is important for normal grouth, puberty and protien synthesis. this variety of roles accounts for the constellation of symptoms and signs encounter in patients with thyroid dysfunction.

Thyroid storm is a life treatening form of hyperthyroidism, whereas myxoedematous coma refers to severe hypothyroidism.
