What is the most common cause of micro nodular cirrhosis?

• A. Autoimmune hepatitis
• B. Alcohol consumption
• C. Chronic viral hepatitis
• D. Alcoholic hepatitis

Answer: (B)

Micronodular cirrhosis arises from repetitive hepatocyte injury with cycles of degeneration and regeneration, producing many small regenerative nodules. Chronic alcohol use is the classic driver of this pattern because alcohol damages liver cells, promotes steatosis, inflammation, and progressive fibrosis over time, leading to uniform, tiny nodules scattered through the liver. That’s why alcohol consumption is the best answer for the most common cause of micro nodular cirrhosis. Alcoholic hepatitis is a related alcohol-related liver condition, but it’s an acute or subacute inflammatory state that can progress to cirrhosis; it isn’t itself the typical cause of the micronodular pattern. Autoimmune hepatitis and chronic viral hepatitis can cause cirrhosis as well, but the characteristic micro nodular pattern most strongly points to chronic alcohol exposure.
