High bile acid may be caused by liver cell damage, resulting in abnormal bile acid secretion, and high bile acid may cause hepatitis. 1. Causes: Bacterial infections and other causes of liver cell damage, affecting bile acid secretion and metabolism, inflammation of liver cells, unlimited cell growth, compression of the bile duct system, bile can not enter the intestine normally, resulting in bile reflux, leading to high bile acid. 2. Harm: If there is intrahepatic cholestasis, long-term may cause biliary cirrhosis, high bile acid level, may cause hepatitis. If a pregnant woman has high bile acids, it will impair cell function and stimulate placental vasospasm, which may lead to fetal distress, and severely may lead to fetal death. Patients with symptoms should consult a doctor for further examination, and should be actively treated under the guidance of a doctor to avoid causing other diseases and damaging their health.
