After the normalization of ALT should be combined with the cause of the disease to analyze the need to continue to take medication: if the cause of the disease is due to drug-related liver injury, then there is no need to continue to take medication; if the cause of the disease is cirrhosis, hepatocellular carcinoma, viral hepatitis and so on, then it is necessary to continue to take medication until the disease is cured. 1. If there is an elevation of ghrelin caused by drug-related liver injury. After adjusting the medication according to the situation, the enzyme will gradually return to the normal level. In this case, there is no need to continue taking medication. 2. In case of cirrhosis, hepatocellular carcinoma or viral hepatitis, it is impossible to conclude that the above mentioned diseases have been cured simply by the normalization of ALT after taking medication. Even if the transaminases return to normal, the disease is not cured as long as the virus or cancer cells that caused the transaminases have not been eliminated. Therefore, it is still necessary to continue to take medication in this case. It is recommended that patients consult a doctor at a regular hospital to determine the cause of the disease and take medication as needed to avoid delays.
