Cirrhosis (hepaticsclerosis) is a common chronic progressive clinical liver disease with diffuse liver damage formed by the long-term or repeated action of one or more etiologies. Pathological histology includes extensive hepatocyte necrosis, nodular regeneration of residual hepatocytes, connective tissue hyperplasia and fibrous septum formation, leading to structural destruction of liver lobules and pseudobullet formation, and progressive deformation and hardening of the liver to cirrhosis. Clinically, liver function impairment and portal hypertension are the main manifestations, and there is multi-system involvement. Complications such as upper gastrointestinal bleeding, hepatic encephalopathy and secondary infections often occur in the late stage. Common causes: 1. Chronic hepatitis B. 2.Chronic hepatitis C. 3.Long-term heavy alcohol consumption. 4.Biliary cirrhosis. 5.Hepatomegaly. 6.Cirrhosis of the liver of unknown origin. Therefore, if patients have the above conditions, they need to promptly detect and consult a doctor and make relevant interventions, so as not to let the disease progress to the stage of cirrhosis, because once liver cell necrosis and regeneration are initiated, most of them are irreversible processes, and further progress in the future may be liver cancer, or liver failure, or rupture and bleeding from esophagogastric varices caused by cirrhosis, etc., leading to death in serious cases. If the above factors exist, in addition to the need to remove the causative factors, patients should also pay attention to life, avoid excessive physical labor, avoid drug abuse, and pay attention to long-term small amounts of multiple protein supplements to slow down the progress of the disease.
