Most liver diseases are difficult to treat even though the cause of the disease is clear. For example, for hepatitis B virus infection, so far there are only drugs that inhibit viral replication, but there are no definitive drugs that clear the virus. Therefore, caution is needed in the treatment of chronic hepatitis B. Only patients who meet the indications for antiviral therapy are suitable for antiviral therapy, and therefore all regimens of medication and examinations should be carried out with caution and thoroughness. A more aggressive antiviral strategy is generally advocated for patients with hepatitis C, as a cure is possible for hepatitis C patients, and first-line treatment can now cure 50% of patients, whereas the treatment of hepatitis A and E patients is mainly symptomatic, and there is no specific treatment regimen. For patients with fatty liver disease, many doctors and experts recommend low sugar, low fat, high fiber foods and a certain level of physical activity. However, it is difficult to do so, as most NAFLD patients have work and lifestyle habits that make it difficult to make the appropriate changes in these patients. Application of drugs to stop the progression of fatty liver is the current research hotspot, but there is still a lack of unified conclusion, some traditional Chinese medicine treatment has a certain effect, such as silymarin has a relatively clear anti-fibrotic effect on patients with fatty liver disease. Alcoholic liver disease patients should quit drinking in time, so as not to cause further liver damage, in general, the daily consumption of alcohol for men is not more than 20g (about 50 degrees of white wine 50ml or 12 degrees of red wine 200ml), and for women is not more than 10g (about 25ml of 50 degrees of white wine or 12 degrees of red wine 100ml) are safer, and even beneficial to the health of the body, once a large amount of alcohol abuse or daily Drinking more than 40g (about 100ml of 50-degree white wine or 400ml of 12-degree red wine), drinking for more than five years, or drinking more than 80g (about 200ml of 50-degree white wine or 800ml of 12-degree red wine) per day in two weeks may cause liver damage. Autoimmune liver disease patients are gradually increasing, but not all autoimmune liver disease patients need to apply hormone therapy, only those with therapeutic indications of autoimmune hepatitis, the application of hormone therapy will get better results. In the early stage of primary biliary cirrhosis, ursodeoxycholic acid is mainly applied to treat patients, and if the effect is ideal, it will not affect the life of patients, once the patients enter the stage of decompensated cirrhosis, the drug treatment is generally ineffective and can only be improved by liver transplantation. Patients with autoimmune liver disease who have progressed to the cirrhotic stage often have to rely on liver transplantation.
