Hepatitis B fibrosis can progress to cirrhosis after 3 to 10 years in general, and the average time is about 5 years, the specific time varies individually, and is related to the state of the liver and whether it is actively treated. Hepatitis B fibrosis is caused by hepatitis B virus infection, resulting in hepatocellular necrosis, destruction of normal hepatic lobular structure, increased intrahepatic cytokine production and collagen synthesis, reduced descending enzymes, capillarization of hepatic sinusoids, and diffuse proliferation of fibrous tissue. Blood circulation in the liver is impaired, and the liver gradually deforms and hardens, and its function gradually deteriorates. If no active control is given, it can progress to cirrhosis in about 3~10 years, and may even progress to liver cancer. Hepatitis B fibrosis patients are advised to seek timely medical treatment and follow the doctor’s instructions to control the condition.
