The total bile acid is still high after giving birth to a child, which may be caused by acute hepatitis or cirrhosis and other diseases that cause bile excretion obstacles, and lead to a pathologic elevation of bile acid. Pregnant women’s livers are unable to excrete bile acids in time, which can cause high bile acids, and this kind belongs to physiologic high bile acids. Intrahepatic cholestasis during pregnancy will return to normal at the end of pregnancy, so the bile acid will gradually decline until it returns to normal after the mother gives birth. If bile acid is elevated, abdominal ultrasound and other tests are needed to investigate the cause of the pathologic elevation of bile acid, which usually occurs when the mother has abnormal liver lesions, such as acute hepatitis or cirrhosis and other diseases leading to obstruction of the bile ducts of the liver and obstruction of the excretion of bile acid, which will result in a high level of bile acid, and timely consultation with the gastroenterology department is needed.
