正常肝脏脂类含量约为肝重的4%～5%,其中2/3为磷酯,此外为中性脂肪、胆固醇、胆固醇酯等,脂肪肝系中性脂肪在肝内蓄积过多所致。酯类在肝内蓄积超过肝重的5%,或在组织学上50%以上的肝实质脂肪化时,均可称为脂肪肝。按照肝内含脂量的多少而分为轻、中、重三度,轻度脂肪肝含脂量为肝重的5%～10%,中度为10%～25%重度在25%～50%或以上。

Normal liver lipid content of about 4% to 5% of liver weight, of which 2/3 for the phospholipids, in addition to neutral fat, cholesterol, cholesterol esters, etc., fatty liver fatty accumulation in the liver caused by too much . Esters accumulate in the liver more than 5% of liver weight, or more than 50% of the histology of hepatic parenchymal fat, can be called fatty liver. According to the number of fat in the liver and divided into light, medium and heavy three degrees, mild fatty liver fat content of 5% to 10% of liver weight, moderate to 10% to 25% severe in 25% to 50 %or above.
