For patients with normal medical checkups, if the blood test for liver function suggests elevated ALT, that is, elevated gammaglutamyltransferase in liver function. The most common reason for this is that in the week before the blood test, the patient has been drinking alcohol, staying up late, working hard and taking drugs or having a bad mood, which will lead to transient liver function damage, that is, the elevation of glutamic oxaldehyde and glutamic oxaldehyde aminotransferases. For such cases, patients need to actively change their daily habits, such as patients do not stay up late, rest more, do not drink alcohol, and keep a happy mood. If it is a non-essential drug, it is recommended that the patient stops taking the drug, and moderately take drugs to reduce aminotransferase, such as biphenyl dibenzoate drops or dicyclomol tablets. Generally, after 5-10 days of active use, and with changes in lifestyle habits, the patient’s liver function will slowly improve and heal. In addition, during the treatment period, patients can take appropriate amount of vitamin C and other drugs, and actively replenish trace elements, which is of positive significance to the recovery of the disease and the maintenance of their own immunity.
