High glutathione and ghrelin in the blood of children represents impaired liver function. Because glutathione and ghrelin are liver enzymes, liver enzymes are released after liver cells are damaged, causing elevated concentrations in the blood and causing elevated liver enzymes. The main causes include the following: first, due to viral infection. If a child has the hepatitis B virus, it can cause hepatitis, resulting in an increase in liver enzymes and even jaundice. Second, due to damage caused by the application of drugs in children. Some drugs are hepatotoxic, and if the drug is used for a long time or applied in large doses, it will cause impaired liver function and also cause high glutamic oxalacetic transaminase and glutamic alanine transaminase, which need to be given to children for timely liver protection treatment.
