title: Effects of hypothyroidism on the respiratory system and control of breathing: Human studies and animal models.
abstract: Hypothyroidism, subclinical hypothyroidism and euthyroid sick syndrome, are prevalent disorders that affect all body systems including the respiratory system and control of breathing. The purpose of this review article is to discuss the regulation of thyroid hormone production and their function at the cellular level; the many causes of hypothyroidism; the effects of hypothyroidism on the respiratory system and on control of ventilation in hypothyroid patients; the variety of ways animal models of hypothyroidism are induced; and how in animal models hypothyroidism affects the respiratory system and control of breathing including neurotransmitters that influence breathing. Finally, this review will present controversies that exist in the field and thus encourage new research directions. Because of the high prevalence of hypothyroidism and subclinical forms of hypothyroidism and their influence on ventilation and the respiratory system, understanding underlying molecular mechanisms is necessary to ascertain how and sometimes why not thyroid replacement may normalize function.
