Overview

Alcoholic liver disease should be differentiated from other diseases that produce similar symptoms, and other types of liver diseases.

• Hemochromatosis
• Wilson's disease
• Viral hepatitis
• Alcoholic hepatitis
• Drug induced hepatitis
• Autoimmune hepatitis
• Cirrhosis
• Cholestatic jaundice

Abbreviations: RUQ= Right upper quadrant of the abdomen, LFT= Liver function test, SIRS= Systemic inflammatory response syndrome, ERCP= Endoscopic retrograde cholangiopancreatography, N= Normal, AMA= Anti mitochondrial antibodies, LDH= Lactate dehydrogenase, GI= Gastrointestinal, CT= Computed tomography
