Normal values for r-glutamyl transpeptidase are 0 to 50 U/L, and normal values for alanine aminotransferase are 0 to 40 U/L. r-glutamyl transpeptidase 52 and a high alanine aminotransferase of 62.5 are not generally considered serious, and are only mildly elevated. Mild elevations of r-glutamyl transpeptidase and ghrelin may be due to transient elevations caused by physiologic factors such as excessive alcohol consumption, overeating, heavy high-fat diets, late nights, and excessive exercise. There is no need to worry about the mild elevation of r-glutamyl transpeptidase and ghrelin due to physiological factors. With positive dietary adjustments and improvement of lifestyle habits, the above indexes may gradually normalize. In addition, mild elevation of r-glutamyl transpeptidase and ghrelin may be caused by hepatitis, alcoholic liver, fatty liver, cirrhosis, liver cancer, bile duct stones, bile duct obstruction, cholangiocarcinoma and other hepatobiliary diseases. All of these diseases may damage liver cells, resulting in elevated r-glutamyl transpeptidase and ghrelin. It is recommended to go to the hospital in time, cooperate with the doctor to do further examination to clarify the cause of the disease, and actively cooperate with the doctor to carry out treatment if it is diagnosed with hepatobiliary diseases.
