In normal people, if a physical examination suggests altered liver echogenicity, the condition is mostly considered to be caused by fatty liver. Fatty liver is classified as mild, moderate or severe, and patients also need to check for hepatitis-related tests, including chronic viral hepatitis B as well as chronic viral hepatitis C. If viral hepatitis and autoimmune hepatitis are excluded and the patient is diagnosed with fatty liver, patients with mild fatty liver need active exercise therapy, including walking and jogging as the main forms of exercise and taking a certain amount of oral health supplements such as deep-sea fish oil to actively lower blood lipids. However, if the degree of fatty liver is more severe, moderate or severe fatty liver should be actively considered to be treated with drugs to lower blood lipids, such as oral atorvastatin to actively lower blood lipids. In addition, patients need to pay attention to eat less animal fat in daily life, and can eat appropriate blended oil and olive oil, and patients also need to actively rest, avoid drinking alcohol, avoid staying up late, and avoid strain.
