A high glutamyl transpeptidase of 200 U/L is an abnormal condition, indicating diseases of the liver and biliary tract, which need to be treated with drugs and surgical methods according to the specific disease. Common causes and treatments 1, liver diseases: common liver diseases include cirrhosis, viral hepatitis, severe fatty liver, alcoholic liver disease, autoimmune liver disease, drug hepatitis, liver abscess, primary liver cancer, etc. Most of them can be diagnosed after doctors ask about the history of medication, liver function test, virus test, immune test and imaging examination. The primary disease can be actively treated, such as liver cirrhosis patients can take adenosylmethionine, reduced glutathione and other drugs for liver preservation treatment. Viral hepatitis can be treated symptomatically with drugs such as glycopyrrolate preparations under the guidance of a physician. Severe fatty liver can be treated by dietary control, combined with lipid-lowering drugs or antioxidants. Alcoholic liver disease may be treated with liver-protective, enzyme-lowering and anti-yellowing drugs as prescribed by the doctor, while alcohol should be avoided. Autoimmune liver disease may be treated with ursodeoxycholic acid, drug-related hepatitis should be discontinued and liver-protective treatment should be performed, primary liver cancer can be treated by surgical resection of the tumor. Therefore, high glutamyl transpeptidase can be found during the examination. Patients with gallstones can take dehydrocholic acid tablets or ursodeoxycholic acid tablets to promote bile excretion and control inflammation. Depending on the condition, surgical treatment such as endoscopic ERCP, stenting or nasal bile duct, laparoscopic cholecystectomy, open cholecystectomy, common bile duct dissection and T-tube drainage can also be performed.
