Alcoholic liver disease
Etiopathogenesis=.Alcohol intake..
Alcohol is metabolised by liver to acetaldehyde by mitochondrial enzyme,ADH.
Acetaldehyde forms adducts with cellular proteins in hepatocytes which activate immune system,leading to cell injury.
Acetaldehyde then metabolised to acetyl coA nd acetate by ALD,this generate NADH,which changes redox pontential of cell
Cytochrome CYP2E1 is induced by alcohol,which generates microsomal peroxidation leading to oxygen free radicals formatn leading to mitochondrial damage

.Raised GGT wil b elevated in hepatic steatosis nd fibrosis

.MANAGEMENT=
.Cessatn of alcohol consumptn.Life long abstinence is best advice
.Treatment of complicatn of cirrhosis such as variceal bleeding ,ecephalopathy nd ascites
.Nutrition is imp nd enteral feeding via fine bore nasogastric tube needed.
.Corticosteroids r of valve in pt with severe alcoholic hepatitis
.Pentoxifylline,a weak anti TNFaction beneficial in sever alcoholic hepatitis
