There is no specific time point in the clinic for the return of normal liver function, and it depends on the type of liver function abnormality and the degree of abnormality. Damage to the liver by certain pathogenic factors, such as infection, alcohol abuse, and drug use, can lead to damage to the morphological structure of the liver and abnormal liver function. For liver function abnormalities caused by heavy alcohol consumption, liver function can gradually return to normal levels about 2-4 weeks after alcohol abuse is stopped. For liver function damage or abnormalities caused by viral hepatitis, such as hepatitis B and C, it takes about 4-8 weeks for liver function to return to normal. In the case of liver cirrhosis, liver cancer and other diseases with damaged liver parenchyma, liver function is less likely to return to normal. After discovering abnormal liver function, it is important to go to the liver disease department of the hospital for relevant examinations in order to clarify the cause and then target treatment. If it is caused by drinking alcohol, overwork, staying up late, obesity, taking drugs and other factors, it is necessary to promptly adjust the diet and living habits, pay attention to rest and reasonable diet.
