After drinking alcohol, whether it is white wine, red wine or beer, alcohol is mainly metabolized in the liver. Ethanol is metabolized to acetaldehyde by ethanol dehydrogenase, acetaldehyde is metabolized to acetic acid by acetaldehyde dehydrogenase, and finally to water and carbon dioxide. Acetaldehyde is a very active substance that can combine with proteins to form acetaldehyde protein complex, which can cause direct damage to the liver, and can stimulate the body’s humoral and cellular immunity and induce immune damage to liver cells, so there is a possibility of transient elevation of transaminases after drinking alcohol, especially the elevation of glutamic aminotransferase, glutamic oxalacetic aminotransferase and gamma-glutamyl transpeptidase, which indicates The occurrence of acute hepatitis and acute liver injury. In addition, beer contains a lot of purine substances, which will produce uric acid after metabolism, and drinking a lot of beer will lead to high uric acid in kidney function tests.
