Metahemoglobinemia adquirida

Toggle: English / Spanish

Definición

La metahemoglobinemia es un trastorno sanguíneo en el cual el cuerpo no puede reutilizar la hemoglobina después de que ésta se daña. La hemoglobina es la molécula que transporta el oxígeno y que se encuentra en los glóbulos rojos. En algunos casos de metahemoglobinemia, la hemoglobina es incapaz de transportar el oxígeno de manera efectiva a los tejidos del cuerpo.

La metahemoglobinemia adquirida resulta de la exposición a ciertos fármacos, químicos o alimentos.

La afección también se puede transmitir de padres a hijos (hereditaria). Ver: metahemoglobinemia
