Higher values of gamma-glutamyltransferase generally indicate a more serious condition, but cirrhosis, acute pancreatitis and other diseases may have insignificantly elevated values, which does not mean that the disease is not serious. The normal value of gamma-glutamyltransferase is 10-50 U/L. Elevated values can be seen in conditions such as alcohol consumption, strenuous exercise, birth control pills, viral hepatitis, cirrhosis, acute pancreatitis, cholelithiasis, and so on. For example, patients with advanced cirrhosis can be complicated with hepatic encephalopathy, upper gastrointestinal bleeding, ascites, etc., which will greatly affect the quality of life and even jeopardize the life; such as drinking alcohol, strenuous exercise, etc., which usually does not cause too serious consequences, and often can be recovered by conditioning. Extremely elevated values can be seen in liver cancer, pancreatic cancer and other diseases. These diseases are more serious, with poorer treatment and prognosis. For the analysis of gamma-glutamyltransferase values, it is recommended that patients consult a doctor in a timely manner to determine their condition by combining other auxiliary tests, symptoms and signs.
