Fatty liver is a disease caused by a variety of causes of lipid metabolism disorders, so that the fat content of liver cells abnormally increased. Under normal circumstances, the total amount of fat in the liver does not exceed 5% of the liver weight, while in the case of fatty liver, the total amount of fat can be as high as 40%-50% of the liver weight, thus affecting the normal function of the liver. 2.Is fatty liver common? –It is a disease whose incidence is increasing year by year! Generally speaking, fatty liver is insidious and does not have many clinical symptoms in the early stage, so it is ignored by the modern people who are busy all day long.

Studies have found that about 2.5%-5% of patients with fatty liver can develop into cirrhosis or even liver cancer. Patients with fatty liver who allow the disease to progress freely may eventually develop cirrhosis and prematurely end their lives. In terms of the pathogenesis of fatty liver, the majority of patients with fatty liver are not simply suffering from fatty liver disease, but also have many “difficult brothers”, such as diabetes, hyperlipidemia, hypertension, etc., who travel together and stay with the patient for life.
