Low glutathione is usually normal and is not clinically significant. Glutathione is found mainly in the cells of the liver and heart tissue, with hepatocytes predominating. Usually, a range of 0-40 U/L in the blood is considered normal, and a range of less than 3 U/L is considered low and does not point to the presence of any disease and generally does not require treatment. When the liver is damaged or the heart is damaged, the release of glutathione into the blood causes an elevation of glutathione in the blood, so elevated glutathione in the blood is a sensitive indicator of acute hepatocyte or cardiomyocyte damage. Common diseases that cause elevated glutathione include liver disease, heart disease, biliary tract disease, and infectious diseases. Some non-disease factors such as strenuous exercise, staying up late, and excessive fatigue can also lead to elevated GLT. In daily life, you should avoid liver or other visceral damage that can lead to elevated ALT through healthy diet, reasonable exercise and good lifestyle habits: 1. Healthy diet: coarse and fine, reasonable meals, and try to eat less greasy food such as roast meat. Try to eat fresh vegetables and fruits, such as bananas, celery, etc., eat less refined food such as cakes, snacks, etc., quit smoking, quit drinking; 2, reasonable exercise: moderate exercise can improve immunity, try to choose the right way to exercise, avoid overwork; 3, good habits: work life should pay attention to try to avoid staying up late and excessive fatigue, to maintain good habits not only to improve efficiency, but also Can protect the liver and avoid liver damage.
