The time required for transaminase 200 U/L to fall to normal is related to the early or late removal of its cause, with faster recovery with active treatment. If the aminotransferases are elevated due to drug factors, they can return to normal within 2-3 days after stopping the drug. The standard transaminase test is 40 U/L. When the transaminase is 200 U/L, it means that the transaminase has exceeded 5 times the normal value, and generally speaking, exceeding 2 times the normal value means that the liver has been damaged. In this case, if you want to bring the transaminases down to normal, you need to clarify the cause and treat the cause. If it is caused by fatty liver, we need to solve the problem of fatty liver; if it is caused by virus, we need anti-viral treatment; if it is caused by drug factor, we need to remove the suspicious drugs and carry out the corresponding treatment of liver protection and enzyme reduction. Therefore, transaminase 200 U/L needs to be removed from its etiology before it can be reduced to the normal reference range, and the length of time required during treatment is subject to individual variability, so no clear time frame can be given. In addition, patients with high transaminases can promote recovery of liver function by eating vitamin-rich vegetables and fruits, such as shiitake mushrooms and pears.
