If the patient’s upper abdominal ultrasound indicates that the patient’s liver area is dense with light spots, the patient is most likely to have a fatty liver. If the patient has hypoechogenicity, the patient is considered to have mild or moderate fatty liver. If the patient has a severe fatty liver, it may cause the possibility of a heterogeneous fatty liver, which may further cause lamellar hypoechoic areas in the patient. In these cases, if the patient has a mild or moderate fatty liver, it is recommended that the patient also have a blood test to see if there is an elevation in blood lipids. If the patient’s blood lipids are normal and the fatty liver is only mild, the patient is advised to exercise more, eat more vegetables and fruits, and avoid eating animal fats and offal. Avoid eating foods with high cholesterol, such as egg yolk and seafood squid, which contain high cholesterol. Patients should be careful to eat more blended oils and olive oil instead of single vegetable oils. For patients with moderate or severe fatty liver, combined with elevated blood lipids, in addition to actively changing their daily habits, they should also take simvastatin or atorvastatin when necessary to actively reduce blood lipids, and pay attention to eating more acidic foods and fruits. Pay attention to more exercise and avoid patients resting after meals or sleeping or lying in bed for a long time without exercise.
