Liver fibrosis is the intermediate link between the development of chronic liver disease and cirrhosis, and is also a common pathological change in many chronic liver diseases. The mechanism of its occurrence is the body’s repair response to inflammation, just as scars form in trauma. A person with chronic liver disease is often accompanied by liver fibrosis, which if left untreated will continue to progress until it develops into cirrhosis, leading to serious complications such as portal hypertension, ascites, hepatic encephalopathy and even hepatocellular carcinoma. If the progression of liver fibrosis can be halted or reversed, it will improve the quality of survival of patients and improve their long-term prognosis to a great extent.
