Non-alcoholic fatty liver disease (NAFLD) is a disease of excessive fat deposition in hepatocytes excluding alcohol and other definite liver-damaging factors. It includes simple fatty liver, steatohepatitis and fatty cirrhosis. NAFLD is an important cause of chronic liver disease in affluent areas of China, with a prevalence of 10% to 30% in the general adult population, of which 10% to 20% is steatohepatitis, with the latter having a 25% incidence of cirrhosis within 10 years. Most of our common fatty liver is the result of excess nutrition, that is, eating too much, of course, there is also malnutrition fatty liver, that is because of vitamin deficiency, protein synthesis raw material deficiency and other reasons leading to lipid metabolism disorders. At present, the citizens of China have basically solved the problem of food and clothing, and the fatty liver patients received by the clinic are mainly those who are over-nourished. The most fundamental treatment for fatty liver caused by overnutrition is to control diet and strengthen exercise, but when the liver function of severe fatty liver is not normal, the amount of exercise should be controlled, and diet control should be the main focus, and weight loss should not be too fast, an average of 3Kg per month is enough, if weight loss is too fast, a large amount of fatty acids will accumulate in the liver can not be transformed in time, it will further aggravate fatty liver, and even develop into fatty liver Failure. At present, there is no good way to treat fatty liver in Chinese medicine and western medicine, western medicine lipid-lowering drugs are not effective in treating fatty liver, if the blood lipid concentration is reduced by reducing fat decomposition, but the fat in the liver will not be reduced after the blood lipid is lowered, because the fat decomposition outside the liver is reduced and the fat decomposition inside the liver is also reduced; if it is a drug that promotes fat metabolism and decomposition, a large amount of fatty acid will enter the liver, and because the liver cannot Some weight loss drugs reduce fat absorption, but they can also affect the absorption of vitamins and other important nutrients and have many side effects. Simple fatty liver liver function is normal without drug therapy, once the fatty hepatitis transaminases are elevated can be treated with silymarin drugs or polyenes (phosphatidylcholine), which can reduce the oxidative inflammatory damage caused by fatty acids and their metabolites, slowing the progress of liver fibrosis, but not much to reduce the role of fat deposits in the liver, so the most fundamental approach to the treatment of fatty liver is to control diet and Physical exercise. Be careful not to engage in starvation therapy, fasting will aggravate the fatty liver, diet with vegetables, protein-based, staple foods (rice, flour, etc.) to eat less, appropriate consumption of fruit, exercise should be less strenuous exercise more aerobic exercise, the best daily exercise 2 hours, such as walking 10 km. Please do not be superstitious that drugs can cure fatty liver.
