GGT is glutamyltransferase. Whether or not a high glutamyltransferase level can be self-healed is related to the cause of its high level, and if it is high due to physiologic factors, it may be self-healed. Glutamyltransferase is an enzyme that catalyzes the transfer of γ-glutamyl group from glutathione to another peptide or another amino acid. It is mainly involved in the metabolism of glutathione and is used clinically in the diagnosis and prognosis of hepatobiliary diseases. The normal value of serum glutamyltransferase is between 9 and 50 U/L. Whether high glutamyltransferase can be cured by itself is related to the causes of high glutamyltransferase, as follows. 1. Physiological factors: If high glutamyl transferase is caused by physiological factors such as irregular diet, late night, lack of exercise, smoking and drinking, high glutamyl transferase may be cured by itself after improving diet and living habits and removing related triggers. 2. Pathological factors: high glutamyl transferase is also seen in viral hepatitis, alcoholic hepatitis, cirrhosis, fatty liver, biliary tract tumors and other pathological factors, at this time, we need to target the cause of the drug treatment or surgical treatment. When glutamyltransferase index is abnormal, it is recommended to consult a doctor in time for a clear diagnosis, and not to judge the severity of the disease on your own, so as to avoid delaying the disease and causing adverse effects.
