1.Etiological treatment Etiological treatment is the most crucial and effective treatment method. Patients with alcoholic fatty liver need to stop drinking, obese fatty liver should be treated with weight loss, malnourished fatty liver needs to be treated with nutrition, fatty liver caused by hyperlipidemia should be given lipid-lowering treatment, acute pregnancy fatty liver needs to be aborted in time, drug fatty liver should stop using the corresponding drugs that cause fatty liver. 2.Treatment to delay disease progression For patients who cannot be effectively treated for subjective or objective reasons, especially for patients with steatohepatitis and liver fibrosis, liver-protective drugs and anti-fibrotic drugs should be given to delay disease progression and prevent the formation of liver cirrhosis. 3.Treatment of concomitant diseases Patients with fatty liver, especially obese fatty liver, are prone to diabetes, hypertension, hyperlipidemia and coronary heart disease, etc. The treatment of the above concomitant diseases in patients with fatty liver should be strengthened. 4.Early treatment In theory, after removing the causes of simple fatty liver, the fatty liver can be completely restored to normal. Even at the stage of steatohepatitis, if active treatment is given, the diseased liver can be completely reversed, but if it develops to the stage of cirrhosis, even if active treatment is given, the diseased liver cannot be restored to normal. Therefore, fatty liver should be treated as soon as possible after it is detected.
