Cirrhosis is defined by progressive fibrosis that bridges across the liver and regenerating nodules, which together destroy the normal liver architecture. This architectural distortion results from chronic injury and inflammation, activating stellate cells to lay down scar tissue. Over time, the fibrous bands and nodules distort the lobular structure, disrupt blood flow, and impair liver function, leading to complications like portal hypertension and reduced synthetic capacity. This architectural destruction is the hallmark feature of cirrhosis, whereas hepatitis centers on inflammation, jaundice is a symptom from excess bilirubin, and Reye’s syndrome involves acute fatty changes with mitochondrial dysfunction rather than chronic architectural collapse.
