脂肪肝是指诸多病因引起的脂类在肝内的沉积。严格地讲,脂肪肝是一个病理学概念,而不是一个独立的疾病。一般而言,当肝内脂类含量占到肝重的5～10%以上时,即称之为脂肪肝,而肝炎后脂肪肝是病毒性肝炎的一种合并症,多发生在肝炎的恢复期或稳定期,急性慢性肝炎均可引起。由于我国是病毒性肝炎的高发病区,近年来,肝炎后脂肪肝在临床上已较为常见。肝脏在脂类的消化、吸收、分解、合成及运输过程中均起重要的作用。正常生理情况下。这些环节处于动态平衡中,肝脏正是维系这个平衡的关键所在。当某些病因引起动态失衡后,就出现病理改变——脂类在肝内沉积形成脂肪肝。具体地说,肝脏分泌胆汁酸盐至肠腔,以促
Fatty liver refers to the deposition of lipids in the liver caused by many causes. Strictly speaking, fatty liver is a pathological concept, not an independent disease. In general, when the intrahepatic lipid content accounts for more than 5 to 10% of liver weight, which is called fatty liver, and posthepatitic fatty liver is a complication of viral hepatitis, mostly in the recovery of hepatitis Period or stable period, acute chronic hepatitis can cause. As China is a high incidence of viral hepatitis, in recent years, hepatitis, fatty liver has been clinically more common. The liver plays an important role in the digestion, absorption, decomposition, synthesis and transport of lipids. Under normal physiological conditions. These links are in dynamic equilibrium, and the liver is the key to maintaining that balance. When some causes a dynamic imbalance, a pathological change occurs - lipids deposit in the liver to form fatty liver. Specifically, the liver secrete bile salts to the intestine to promote
