The normal range of glutamyltransferase is 11~50U/L for men and 7~32U/L for women.When glutamyltransferase is elevated to 131, it is not considered serious, but it needs to be taken seriously, and go to the hospital in time for examination and clarification of the cause of the disease. The causes of elevated glutamyltransferase are divided into physiologic and pathologic, and pathologic diseases are generally considered to be diseases of the liver and gallbladder. 1. Physiological: excessive alcohol consumption, overeating, large amounts of high-fat diets, staying up late, excessive exercise may lead to transient elevation of glutamyl transferase, in the case of active adjustment of dietary structure and improvement of lifestyle habits, aminotransferase will usually return to normal. 2. Pathological: hepatitis, alcoholic liver, fatty liver, cirrhosis, liver cancer, bile duct stones, bile duct obstruction, cholangiocarcinoma and other liver and gallbladder diseases may damage the liver cells, resulting in increased glutamyl transferase. If elevated glutamyltransferase occurs, one should go to the hospital in time to clarify the cause of the disease, and if it is caused by pathological factors, one should actively carry out treatment under the guidance of the doctor.
