A simple decrease in glutamic oxalacetic aminotransferase with no combination of other symptoms usually has no specific damage to the body and is not pathologically significant. Glutamate aminotransferase is also known as aspartate aminotransferase in clinical practice, and most of the low values are normal, mainly related to recent dietary factors or physical factors. 1. Dietary factors: mainly due to the recent low protein content in the diet, which can be increased by increasing the amount of protein-rich foods, such as eggs, milk, lean meat, etc.; 2. 2, physical factors: mainly due to the recent consumption of body functions, such as infections, tumors, autoimmune diseases, etc., consuming too much protein in the body, resulting in lower values of ghrelin. In human body, glutathione is mainly distributed in mitochondria of cardiac muscle cells and liver cells, and also in muscles, such as heart muscle and skeletal muscle. No specific treatment is usually necessary. Patients are advised to visit the hospital regularly to review and test for changes in the values of aspartate aminotransferase. It is important to note that the presence of liver damage is reflected in clinical practice mainly by whether the value of aspartate aminotransferase is elevated and the ratio to glutamate aminotransferase. If liver damage is present, such as acute jaundice, chronic active hepatitis, cirrhosis, liver cancer and other diseases, patients are advised to go to the hospital in time to avoid further aggravation of liver damage.
