High GST is usually caused by non-disease factors such as alcohol consumption and excessive exercise, as well as disease factors such as hepatitis and cirrhosis, which need to be analyzed specifically. 1. Non-disease factors: Drinking alcohol and over-exercise will overburden the liver and damage the tissue cells, which will release the enzyme into the blood and make the test result high. 2. Disease factors: (1) Viral hepatitis: if there is infection of hepatitis B virus and other curative factors, it will lead to damage of liver cells, which will cause elevation of glutamine aminotransferase. (2) Cirrhosis: in addition to viral hepatitis, fatty liver, alcoholic liver, drug liver injury, etc., may also cause liver cirrhosis, at this time the metabolic disorders in the liver, which will lead to the release of glutamic oxal transaminase into the blood, resulting in elevated indicators. Based on the test results of elevated liver indicator of glutamic oxal transaminase alone cannot accurately determine the cause of the disease, it is recommended to consult a doctor in a timely manner to clarify the cause of the disease under the guidance of the doctor, and symptomatic treatment.
