In general, fatty liver can cause liver function abnormalities. Fatty liver, short for fatty liver disease, is a group of clinical syndromes characterized by hepatocellular steatosis specifically and pathologically caused by genetic, environmental, and metabolic stress factors, mainly including alcoholic fatty liver disease, non-alcoholic fatty liver disease, and special types of fatty liver disease, of which non-alcoholic fatty liver disease is more common. The fatty degeneration or even necrosis of hepatocytes is caused by the attachment of excessive adipose tissue in the interstitial space of hepatocytes or on the surface of hepatocytes. When the transaminases and other substances in the liver cells are released into the blood, abnormal blood biochemical test results of liver function can appear, such as elevated menthyl aminotransferase, etc. When fatty liver progresses to the stage of cirrhosis, symptoms such as liver palms, spider nevus, lower limb edema, ascites and jaundice can also appear. It is recommended that patients with fatty liver should seek medical treatment in time and under the guidance of the doctor for targeted treatment.
