Which statement best describes cirrhosis and its common etiologies?

• A. It is chronic liver disease with parenchymal degeneration and fibrous tissue; etiologies include alcohol use, malnutrition, chronic hepatitis, nonspecific infections
• B. It is acute liver failure due to acetaminophen toxicity
• C. It is a congenital malformation of the hepatic arteries
• D. It is a reversible fatty change of the liver

Answer: (A)

Cirrhosis is a chronic liver disease characterized by irreversible scarring with degeneration of liver cells and the formation of fibrous tissue that distorts the normal architecture into nodules. This ongoing damage activates scar-forming cells and disrupts blood flow and liver function, leading to issues like portal hypertension and decreased synthetic capacity. The etiologies listed—long-term alcohol use, malnutrition, chronic hepatitis, and nonspecific infections—reflect common, sustained insults that drive this fibrotic process. Other statements describe conditions that are either acute in onset, such as acute liver failure from a toxin, or structural or metabolic changes that do not produce the same chronic, fibrotic remodeling seen in cirrhosis (for example, a congenital vascular anomaly or reversible fatty change).
