The normal range of bilirubin is 1.71-21 μmol/L. Whether the bilirubin can heal itself depends on the cause of the high bilirubin, whether it is a daily habit or a disease factor. High bilirubin may be related to behavioral habits. If high bilirubin is caused by alcohol consumption or excessive obesity, it can be self-healed by proper exercise and abstinence from alcohol. However, if the high bilirubin is caused by diseases, such as hepatitis A, hepatitis B, liver cirrhosis, and hemolytic disease, it may cause high bilirubin. Acute hepatitis such as hepatitis A and hepatitis E can be treated with symptomatic support, and the bilirubin can slowly fall back to the normal range, while viral hepatitis B also requires antiviral treatment. Patients should pay attention to liver health care in daily life, drink less alcohol, eat less fatty food, and go to a specialized liver department for further examination if they are unwell to prevent more serious diseases from occurring.
