An elevated GLTA indicates damage to liver cells. Glutathione is very sensitive to liver cell damage. A mild elevation of ALT indicates abnormal liver function. However, there are many causes of liver cell damage, so it is important to look for the cause. If the cause is staying up late or straining, most of them will improve quickly after sufficient rest, even without liver-protective and enzyme-lowering treatment. If the cause is steatohepatitis, it is necessary to control the weight within a reasonable range and to control the diet, not to eat excessively greasy food, and also need to strengthen a certain intensity of physical exercise. If the liver function is abnormal due to alcoholic hepatitis, it is enough to stop drinking. If the liver function is abnormal due to viral hepatitis, it needs to be treated according to the specific type of virus. In the case of hepatitis B, standardized anti-hepatitis B virus and other comprehensive treatment will be required if necessary. If it is hepatitis C, it is now possible to completely eradicate it.
