Which of the following is a common etiological factor in liver cirrhosis?

• A. High blood pressure
• B. Chronic viral hepatitis
• C. Dietary fiber deficiency
• D. Obesity alone

Answer: (B)

Chronic viral hepatitis is a leading cause of liver cirrhosis due to the long-term inflammation and damage it inflicts on liver tissue. Hepatitis B and C viruses, in particular, can cause ongoing liver cell injury and inflammation, resulting in fibrogenesis and ultimately leading to cirrhosis if left untreated. The persistent infection triggers a cycle of liver injury, regeneration, and fibrosis, which culminates in the scarring characteristic of cirrhosis.

Factors such as high blood pressure and dietary fiber deficiency are not directly linked to the development of cirrhosis. While obesity can contribute to liver issues like non-alcoholic fatty liver disease, it is not a standalone cause of cirrhosis without the presence of additional factors such as alcohol use or viral infections. Thus, chronic viral hepatitis stands out as a significant etiological factor in the development of liver cirrhosis.
