O hipotireoidismo está presente quando os níveis séricos de hormônio tireoidiano estão abaixo do intervalo de referência, indicando insuficiência tireoidiana. No hipotireoidismo manifesto devido à disfunção da tireoide (hipotireoidismo primário), os níveis de tireotropina (muitas vezes referido como hormônio estimulante da tireoide ou TSH) estão adequadamente elevados. Por outro lado, o hipotireoidismo subclínico existe quando os níveis séricos desse hormônio estão dentro do intervalo de referência, mas os níveis séricos de TSH estão elevados fora do intervalo de referência. Existe uma controvérsia se o tratamento do hipotiroidismo subclínico traz repercussões positivas na diminuição do risco cardiovascular. Atualmente, o tratamento é indicado na maioria das literaturas. Contudo, sua indicação é pautada em estudos com baixo nível de evidência, e foram desencorajadas com a publicação de ensaios clínicos randomizados a respeito do assunto.
