For a patient with a normal physical examination, if an ultrasound examination of the upper abdomen indicates diffuse changes in the liver parenchyma, it is more likely that the patient is considered to have fatty liver. In this case, the patient needs to be given different treatment according to the severity of fatty liver indicated by the ultrasound. For patients with mild fatty liver, if they do not have symptoms of hyperlipidemia, they should pay attention to exercise, and run and walk moderately. In addition, patients should eat more foods rich in vitamin C, such as oranges, grapefruit, and oranges. In addition, patients should be careful not to drink alcohol, not to stay up late, not to strain, and to pay attention to the normal mood, all have positive significance for the recovery of fatty liver. If the patient is found to have moderate or severe fatty liver on ultrasound, there is a possibility of hyperlipidemia in combination. In general, patients should moderately take deep-sea fish oil supplements, which also have positive significance for the reduction of blood lipids. With the above treatment, the patient’s fatty liver symptoms will generally improve after 1-2 months.
