With the development of economy and the change of lifestyle, The incidence of fatty liver in China is increasing rapidly, But also shows a trend of younger age, Today, the prevalence rate of fatty liver in coastal areas has reached 15%.  Liver is the nutrition transfer station of human body. After the food is digested and absorbed, it reaches the liver along the blood vessels. After hepatocyte treatment, It is converted into substances that can be used by other organs and then transported to the whole body. If the absorbed fat exceeds the liver’s processing capacity, it will deposit in hepatocytes. In addition to affecting the liver’s own function, hepatocytes will also attract attacks from the immune system, causing inflammation, causing liver fibrosis, and eventually taking the irreversible path of liver cirrhosis.  Is it desirable to lose weight? Patients often say: Fatty liver is too much fat, Then losing weight can cure it. You can’t say it too absolutely. However, for most patients with mild, moderate and a few patients with severe fatty liver, Weight loss is the best strategy to reverse fatty liver. The weight loss mentioned here is not just a diet.

It is easier to take medicine than to take medicine. 1. Can liver-protecting drugs treat fatty liver? Clinically, patients often require to prescribe liver-protecting drugs. They mistakenly think that such drugs can cure all kinds of liver diseases. Usually, liver-protecting drugs are only used for abnormal liver function indexes, and their role in the prevention and treatment of fatty liver is still controversial. At present, patients are not recommended to use such drugs routinely.  2. Is health care products useful? If the doctor does not prescribe medicine, some patients will also buy health care products and proprietary Chinese medicines to eat. Little imagine, no matter how good the medicine is, it cannot drive fat out of liver cells. Besides, these health care products with unknown formula may cause damage to liver function and aggravate the progress of liver diseases. 3. What is the best way?

According to current statistics, The incidence of liver cirrhosis in patients with steatohepatitis within 15 years is as high as 15% ~ 25%. [1, 2) Fatty liver not only damages the liver, It is also often accompanied by abnormal glucose and lipid metabolism, which will affect tissues and organs of the whole body. Among patients with fatty liver, the incidence of metabolic syndrome, type 2 diabetes and coronary heart disease is significantly increased.  Some studies have shown that the life expectancy of patients with fatty liver is shorter than that of healthy people, and the main causes of death are malignant tumors, cardiovascular diseases and liver cirrhosis.  Why do you suffer from this disease? To put it simply, Lipid deposition in hepatocytes is the basis of this disease. There may be three reasons for lipid deposition: Excessive intake of lipids and reduction of lipid transport to hepatocytes due to metabolic dysfunction of hepatocytes and deficiency of very low density lipoprotein. Obesity, diabetes, hyperlipidemia, alcohol abuse, malnutrition, drugs, industrial toxicants, gastrointestinal surgery, etc. may all cause problems in liver lipid metabolism pathways. Causing fatty liver.  Of course, genes are also a factor that cannot be ignored. Even if genes are good, they cannot fool around. It is not good to hurt the liver.
