What is cirrhosis primarily caused by?

Cirrhosis is a condition characterized by the progressive scarring of the liver tissue, which can ultimately lead to liver failure. The primary causes of cirrhosis generally include alcoholism, exposure to toxins (poisons), and viral infections such as hepatitis B and C.

Alcoholism is one of the most common causes of cirrhosis, as excessive and prolonged alcohol consumption can lead to liver damage and inflammation, resulting in fibrosis and ultimately cirrhosis. Similarly, exposure to toxic substances can cause liver cells to be damaged, leading to scar tissue formation. Hepatitis is also a significant contributing factor to the disease, as chronic infection with hepatitis viruses can lead to ongoing inflammation and tissue damage over time.

This comprehensive view of the primary causative factors demonstrates why the identified answer accurately reflects the main etiology of cirrhosis.
