As doen\u00e7as da tiroide provocam v\u00e1rios sinais e sintomas  e a queda de cabelo, problemas na pele e enfraquecimento das unhas podem ser alguns deles. Situa\u00e7\u00f5es que podem estar associadas a outras patologias ou at\u00e9 mesmo fases de vida, como a menopausa ou o p\u00f3s-parto, nas quais o hipotiroidismo e o hipertiroidismo t\u00eam um papel significativo.<\/h4>\n\n\n\n

Perda de cabelo<\/strong><\/p>\n\n\n\n

O cabelo passa por fases de crescimento e de repouso. No entanto, os fol\u00edculos capilares est\u00e3o em fases diferentes, pelo que a perda de cabelo \u00e9 cont\u00ednua, mas equilibrada pelo crescimento de novos cabelos.<\/p>\n\n\n\n

Geralmente, s\u00f3 as formas graves de hipotiroidismo e hipertiroidismo provocam queda de cabelo em todo o couro cabeludo, tornando-se apenas vis\u00edvel alguns meses depois. Isto porque, durante a doen\u00e7a, os fol\u00edculos capilares entram numa fase de repouso e deixam de crescer.<\/p>\n\n\n\n

Ainda assim, aquando do tratamento destes dist\u00farbios da tiroide, o cabelo volta a crescer, embora ainda demore v\u00e1rios meses e possa ser incompleto. Por isso, n\u00e3o desanime! No entanto, \u00e9 de notar que o pr\u00f3prio tratamento pode ser a causa da queda do cabelo. Esta situa\u00e7\u00e3o acontece raramente, mas esteja atento. Avalie com o seu m\u00e9dico a verdadeira origem e o melhor caminho a seguir.<\/p>\n\n\n\n

No hipotiroidismo, o cabelo pode apresentar-se mais seco, quebradi\u00e7o e de crescimento lento.<\/p>\n\n\n\n

Especificamente no hipertiroidismo, pode manifestar-se mais frequentemente a alopecia areata, que resulta em perda de cabelo sem cicatrizes, ou o chamado cabelo anelado, isto \u00e9, tem uma apar\u00eancia salpicado ou em faixas, alternado em cores mais claras e mais escuras.<\/p>\n\n\n\n

Altera\u00e7\u00f5es cut\u00e2neas<\/strong><\/p>\n\n\n\n

A pele tem um papel muito significativo na nossa qualidade de vida, mas tamb\u00e9m sofre com as doen\u00e7as da tiroide, associada \u00e0 desregula\u00e7\u00e3o destas hormonas.<\/p>\n\n\n\n

Aquando da presen\u00e7a de hipotiroidismo, o doente pode ter pele extremamente seca, p\u00e1lida ou amarelada e fria, com apar\u00eancia escamosa; pele espessa nas palmas das m\u00e3os e solas dos p\u00e9s; doen\u00e7as de pele mais graves, como erup\u00e7\u00f5es cut\u00e2neas em forma de anel com clareamento central nas n\u00e1degas, coxas e bra\u00e7os; desenvolvimento de vitiligo, isto \u00e9, \u00e1reas de pigmenta\u00e7\u00e3o e de hipopigmenta\u00e7\u00e3o;<\/p>\n\n\n\n

J\u00e1 no hipertiroidismo, ocorre um aumento da circula\u00e7\u00e3o sangu\u00ednea, causando uma sensa\u00e7\u00e3o de calor e vermelhid\u00e3o, nomeadamente na cara e m\u00e3os; pode tamb\u00e9m ter a pele mais fina, prurido e eczema.<\/p>\n\n\n\n

Modifica\u00e7\u00f5es nas unhas<\/strong><\/p>\n\n\n\n

As unhas, por sua vez, tamb\u00e9m s\u00e3o afetadas pelas doen\u00e7as da tiroide. No hipotiroidismo, a manifesta\u00e7\u00e3o mais comum \u00e9 o enfraquecimento, o seu crescimento mais lento e o afinamento da unha.<\/p>\n\n\n\n

No hipertiroidismo, o doente pode sofrer de onic\u00f3lise, isto \u00e9, quando a unha se separa, parcialmente, da pele do dedo.<\/p>\n\n\n\n

Em suma, o cabelo, a pele e as unhas sofrem tamb\u00e9m com as doen\u00e7as da tiroide, pelo que \u00e9 importante manter os cuidados e garantir que est\u00e3o a ser tratados corretamente. Se ainda n\u00e3o foi diagnosticado, mas sente que tem sintomas, pode recorrer ao Avaliador de Sintomas da Thyroid Aware<\/a>.<\/p>\n\n\n\n

Em caso de d\u00favida consulte o seu m\u00e9dico.  <\/p>\n\n\n
