If bile acid is elevated in pregnant women, the first thing to do is to adjust the diet structure, avoid eating high-fat and greasy food, such as fatty meat, animal offal, fried and fast food, and eat more high protein and vitamin-rich food, such as soybean products, dairy products, fish and meat, as well as fresh fruits and vegetables, etc. In addition, further relevant auxiliary examinations should be conducted to determine the specific cause of the increase in bile acid. In addition, relevant auxiliary examinations should be carried out to clarify the specific cause of the increased bile acids. If underlying liver diseases such as viral hepatitis B and cirrhosis existed before pregnancy, it is likely that there is a close relationship with the underlying disease. In patients with markedly elevated hepatitis B viral DNA, if combined with elevated transaminases, they should also be given hepatoprotective and hepatoprotective treatments, as well as the application of antiviral drugs such as lamivudine and tenofovir. If the elevated bile acids are caused by primary sclerosing cholangitis, corticosteroid treatment may also be considered. The elevation of bile acids due to intrahepatic cholestasis in pregnancy should be given high priority, and relevant drugs can be taken orally to reduce bile acids, such as ursodeoxycholic acid, cholestyramine, dexamethasone, and adenosylmethionine, etc. These drugs have a better effect. The level of bile acids and the condition of the fetus should also be closely monitored, such as regular monitoring of the fetal heart rate. If abnormalities are detected, or if the pregnancy exceeds 36 weeks, the pregnancy should be terminated promptly to prevent intrauterine distress and sudden death of the fetus.
