Whether children’s liver function impairment can recover by themselves depends on the condition of the impairment, if the impairment is only slight and the cause of the impairment can be eliminated automatically, generally it can recover by itself, but due to the difference of individuals, the recovery will be different, if the liver impairment is more serious generally it is difficult to recover by itself, and it may be aggravated gradually. The main causes of liver function damage in children are viral infection or drug stimulation and immunologic diseases, all of which can cause different degrees of damage to children’s function, and whether or not they can recover on their own or how they recover will vary due to the different degrees of damage and individual differences. If the liver damage is caused by viral infection and the damage is not very serious, the liver function will recover slowly after appropriate antiviral treatment, if the liver function is damaged by drug stimulation, the liver function will recover only after stopping the medication, and if the liver function is damaged by autoimmune disease, the liver function will recover only after active immunotherapy. Therefore, when children’s liver function is damaged, they should go to the hospital for examination in time, and choose the appropriate treatment according to different situations, so as to avoid affecting children’s growth.
