How long does it take for the blood ghrelin 100 U/L to come down depends on the cause of the elevated ghrelin. Glutathione is an important indicator of liver function, and an elevated value represents some damage to the liver. Under normal circumstances, glutathione is only released into the blood in small amounts, with a normal value of 0-40 U/L in the blood (normal values vary from kit to kit and from lab to lab). When GLTA is 100 U/L, it indicates that liver function has been impaired and can be seen in a variety of liver diseases, such as viral hepatitis, fatty liver, alcoholic liver, autoimmune liver disease, and drug-related liver injury. If it is caused by drug-related causes, it can be reduced to normal in about 4 weeks after removing the drugs that may have caused the elevation of GLT and then administering aggressive liver-protective therapy. If the elevated GTA is caused by viral hepatitis, it can be restored to normal in about 1-3 months after antiviral and hepatoprotective treatment. When glutathione exceeds 2.5 times the upper limit of the normal reference value and remains abnormal for more than half a month, it can be used as a basis for diagnosing hepatitis. People who often take liver-harming drugs or are in the active stage of viral hepatitis should go to the liver disease department of the hospital regularly for liver function and other related tests.
