Alt is alanine aminotransferase and ggt is glutamyl transpeptidase. high alt and ggt are indicative of some impairment of liver function. Alanine aminotransferase is found mainly in hepatocytes and glutamyl transpeptidase is found in the liver mainly in hepatocytes and intrahepatic bile duct epithelial cells. If in the liver, the hepatocytes are damaged, these two enzymes will flow from the hepatocytes into the bloodstream, and the value will be high when checking the liver function. For example, in alcoholic hepatitis, long-term alcohol consumption, alcohol can directly damage and destroy liver cells, and the liver is the main organ involved in metabolism, all the alcohol will flow through the liver, slowly damage to a certain extent, breaking through the liver cells’ own metabolism, will detect alanine aminoacyltransferase and glutamyltranspeptidase high, suggesting that there is a certain degree of damage to liver function. In this case, it is generally recommended to find out the causes of cirrhosis first, and avoid these factors in time, at the same time, you can follow the doctor’s instructions to use the liver-protecting drugs, such as silymarin and dicyclomine to treat. High alt and ggt may also be due to other reasons such as myocardial injury, it is recommended to go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
