Q

Describe the pathophysiology of alcoholic liver disease?

A

The breakdown of alcohol inhibits gluconeogenesis and increases fatty acid oxidation

promoting fatty in filtration and producing free radicals

ree radicals and the deficiency of antioxidants (vitamins E- usually from malnutrition) causes oxidative stress

promotes necrosis and apoptosis

free radicals also cause lipid oxidation causing further inflammation and fibrosis

acetyl-aldehyde a metabolite from alcohol breakdown induces inflammation
