High bilirubin can be caused by a variety of reasons and may decrease on its own without treatment, but it still depends on the specific cause. If bilirubin is elevated due to hepatocellular causes, it can be reduced on its own as liver function recovers. However, bilirubin elevation caused by hemolysis cannot decrease on its own. If the bilirubin is elevated due to obstruction, such as stones, the obstruction needs to be removed by medical means in order for the bilirubin to decrease. If bilirubin is high, you can go to the hospital for ultrasound tests of the liver and biliary area to achieve the right treatment. People who are obese or love to drink alcohol are prone to high bilirubin, so they should avoid drinking alcohol frequently in their daily life, pay attention not to smoke or stay up late, do more exercise and eat less fatty and fatty food to effectively avoid high bilirubin.
