Ausencia del factor intrínseco

Definición:

El factor intrínsico es una sustancia natural que normalmente está presente en el estómago y es esencial para la digestión de la vitamina B-12. La carencia del factor intrínseco ocasiona anemia perniciosa y deficiencia de vitamina B-12.

Los bebés que nacen con carencia del factor intrínseco no pueden absorber apropiadamente la vitamina B-12, comenzando alrededor de los 6 meses de edad, mientras que el tipo juvenil tiende a manifestarse por sí solo después de los 10 años.
