Enfermedad Hepática Alcohólica

La enfermedad hepática alcohólica es un espectro de trastornos que van desde el hígado graso hasta la cirrosis secundaria al AL Amyloidosis abuso crónico de alcohol. El consumo excesivo y prolongado de alcohol da como resultado el deterioro de la vía de la lipólisis, lo que provoca cambios inflamatorios dentro de los LOS Neisseria hepatocitos. Los LOS Neisseria pacientes típicamente se presentan durante la etapa de hepatitis con ictericia, fiebre y dolor Dolor Inflammation abdominal.

Descripción General

Definición

La enfermedad hepática alcohólica abarca la esteatosis alcohólica (hígado graso, reversible), la esteatohepatitis (puede ser reversible) y la cirrosis (irreversible). Todas secundarias al AL Amyloidosis abuso de alcohol.

Tres etapas de la enfermedad hepática alcohólica

Las 3 etapas de la enfermedad hepática alcohólica:
Estas 3 etapas de la enfermedad hepática alcohólica pueden superponerse y no necesariamente ocurren en secuencia: hígado graso alcohólico (reversible), hepatitis alcohólica (reversible si se suspende el alcohol) y cirrosis relacionada con el alcohol (irreversible). También son factores de riesgo para desarrollar carcinoma hepatocelular.
