Causes of high direct bilirubin

High direct bilirubin is mainly caused by bile duct stones, liver diseases, hemolytic anemia and other reasons.

1, bile duct stones

intrahepatic or extrahepatic bile duct stones block bile duct generally cause direct bilirubin excretion disorders, excess direct bilirubin can not be discharged into the blood circulation, and then will cause direct bilirubin in the serum to increase.

2, liver diseases

due to viral hepatitis, liver cirrhosis, liver cancer and other reasons lead to liver cell damage, the body intake, binding and excretion of bilirubin dysfunction, direct bilirubin in the blood accumulation, and then will lead to direct bilirubin higher than normal.

3, bile duct cancer

malignant tumor volume continues to increase, leading to narrowing or obstruction of bile duct lumen, direct bilirubin excretion in the body blocked, and then will lead to direct bilirubin in the serum increased.
