Tiamina - Side Effects

Nombres alternativos

Vitamina B1; Tiamina

Efectos secundarios:

Una falta o deficiencia de tiamina puede causar debilidad, fatiga, psicosis y daño neurológico.

La deficiencia de tiamina en los Estados Unidos se observa con más frecuencia en personas alcohólicas, ya que el consumo excesivo de alcohol dificulta la absorción de la tiamina de los alimentos por parte del cuerpo. A menos que aquellas personas con problemas de alcoholismo reciban cantidades de tiamina superiores a las normales para compensar la diferencia, el cuerpo no obtendrá suficiente cantidad de esta sustancia, lo cual puede llevar al desarrollo de una enfermedad llamada beriberi.

En los casos de deficiencia grave de tiamina, se puede presentar daño cerebral. Un tipo se llama el síndrome de Korsakoff y el otro es la enfermedad de Wernicke. Cualquiera de las dos o ambas enfermedades se pueden presentar en la misma persona.

No existe toxicidad conocida ligada a la tiamina.
