Chronic liver fibrosis is a progressive, debilitating condition due to long-term liver injury from causes like viral hepatitis, excessive alcohol, non-alcoholic fatty liver disease, and autoimmune disorders. It involves excessive collagen accumulation in the liver, disrupting architecture and impairing function. This can lead to nodules, scarring, and cirrhosis if untreated, causing life-threatening complications such as liver failure and cancer. Early detection, managing root causes, and developing treatments to slow or reverse fibrosis are key to improving outcomes and preventing advanced liver disease.
