Metahemoglobinemia adquirida

Toggle: English / Spanish

Definición

La metahemoglobinemia es un trastorno sanguíneo en el cual el cuerpo no puede reutilizar la hemoglobina porque está dañada. 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 suficiente oxígeno a los tejidos del cuerpo.

Causas

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

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