A\u00a0<strong>anemia ferropriva<\/strong>\u00a0\u00e9 a mais comum em todo o mundo e acontece quando o corpo n\u00e3o tem ferro suficiente para produzir hemoglobina. Ela pode ser causada por alimenta\u00e7\u00e3o pobre em ferro, sangramentos menstruais intensos ou problemas na absor\u00e7\u00e3o do mineral pelo intestino.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A\u00a0<strong>anemia megalobl\u00e1stica<\/strong>\u00a0ocorre pela falta de vitamina B12 ou \u00e1cido f\u00f3lico, nutrientes essenciais para a forma\u00e7\u00e3o adequada das c\u00e9lulas vermelhas do sangue.

Valores de hemoglobina abaixo de 13 g\/dL em homens e 12 g\/dL em mulheres j\u00e1 indicam anemia, segundo os crit\u00e9rios da OMS.<\/li>\n\n\n\n<li><strong>Ferritina s\u00e9rica:<\/strong>&nbsp;mede as reservas de ferro no organismo. \u00c9 o exame mais espec\u00edfico para identificar a anemia por falta de ferro. Valores abaixo de 30 ng\/mL geralmente indicam que os estoques est\u00e3o baixos.<\/li>\n\n\n\n<li><strong>Ferro s\u00e9rico e satura\u00e7\u00e3o de transferrina:<\/strong>&nbsp;complementam a avalia\u00e7\u00e3o, mostrando quanto ferro est\u00e1 dispon\u00edvel no sangue para ser usado na produ\u00e7\u00e3o de hemoglobina.<\/li>\n\n\n\n<li><strong>Dosagem de vitamina B12 e \u00e1cido f\u00f3lico:<\/strong>&nbsp;solicitados quando o hemograma sugere c\u00e9lulas vermelhas maiores do que o normal, o que pode indicar anemia megalobl\u00e1stica.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Revis\u00e3o publicada no Journal of Internal Medicine refor\u00e7a a import\u00e2ncia do diagn\u00f3stico precoce<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A necessidade de investigar a anemia com exames de sangue, e n\u00e3o apenas pela observa\u00e7\u00e3o de sintomas, \u00e9 amplamente sustentada pela ci\u00eancia.
