High glutamyl transferase is associated with diseases such as fatty liver, cirrhosis, acute and chronic hepatitis, and in some people it is caused by overwork and heavy alcohol consumption. Glutamyl transferase is a product of liver metabolism, so once it appears elevated, you should be alert to the fact that it is caused by liver cells. Fatty liver can develop into a severe period when the metabolic function of the liver is affected, so mildly high glutamyl transferase can occur. During cirrhosis and acute and chronic hepatitis, the liver cells are severely damaged, even leading to necrosis, which affects the metabolism of glutamyl transferase, resulting in elevated levels. When the body is overworked, the liver function is affected and mildly high glutamyl transferase can occur, and the condition can be improved with proper rest. High glutamyltransferase can also be found when the patient is examined after drinking large amounts of alcohol, which is metabolized in the liver and therefore affects liver function.
