Fatty liver causing elevated alanine aminotransferase indicates that the condition is more serious and effective measures should be taken as soon as possible. Fatty liver tends to cause necrosis of liver cells, which in turn causes ALT to enter the bloodstream and appear as high values. When encountering this situation, it usually indicates that the patient has steatohepatitis, which may cause liver fibrosis and serious cirrhosis if the condition is not effectively controlled. For fatty liver, patients can use polyene phosphatidylcholine and bicyclic alcohol to protect the liver and eliminate inflammation under the advice of healthcare professionals. Secondly, it is important to maintain a healthy lifestyle, control calorie intake and eliminate alcohol consumption. In addition the liver is an important metabolic organ, and fatty liver may lead to abnormal liver function, so it is important to target the regulation of blood pressure, blood lipids and blood sugar. Fatty liver is a big threat to health, so when the condition is serious, we must pay attention to it and actively cooperate with the treatment.
