The dangers of high total bilirubin include the following: First, hepatocellular jaundice may occur, as the patient’s liver cells are damaged, resulting in decreased liver function, which affects the patient’s bilirubin excretion function, and a few patients may have cirrhosis and viral hepatitis. Secondly, obstructive jaundice may occur, as the bile duct is blocked and bile is not excreted normally through the bile duct. Third, hemolytic jaundice may occur, as the red blood cells are damaged to a certain extent, there may be symptoms of pernicious anemia. Once the total bilirubin abnormality appears, you should go to the hospital for the corresponding examination and diagnosis, and carry out treatment according to the diagnosis result.
