Thyroid hormone misuse and abuse

Abstract

Thyroid hormone (TH) plays an essential role in human physiology and maintenance of appropriate levels is important for good health. Unfortunately, there are instances in which TH is misused or abused. Such misuse may be intentional such as when individuals take thyroid hormone for unapproved indications like stimulation of weight loss or improved energy. There are instances where healthcare providers prescribe thyroid hormone for controversial or out of date uses and sometimes in supraphysiologic doses. Othertimes, unintentional exposure may occur through supplements or food that unknowingly contain TH. No matter the reason, exposure to exogenous forms of TH places the public at risk for potential adverse side effects.
