Usually the normal serum range value of glycocholic acid is 0-2.70 mg/L. If it exceeds the normal value, it is a serious condition, only the degree of severity exists. Glycocholic acid is an important biochemical indicator for evaluating biliary stasis in the liver. If the patient has damaged hepatocytes and the ability of hepatocytes to take up glycocholic acid is decreased, or if there is biliary stasis and the ability of the liver to excrete glycocholic acid is impaired, and the level of glycocholic acid entering the blood circulation is increased, it can lead to an increased level of glycocholic acid in the blood. 1. Pregnant women: In late pregnancy, i.e. after 32 weeks of pregnancy, if a pregnant woman has itching of the extremities but not a rash, it is recommended to check liver function promptly. If the test results show high bile acids, an auxiliary test for glycopyrrolate is usually required. Intrahepatic cholestasis during pregnancy is a specific disease of pregnancy and is highly correlated with glycolic acid. If the serum glycolic acid level of a pregnant woman is 2.70-10.00 mg/L, it is mild intrahepatic cholestasis, 10.00-30.00 mg/L is moderate intrahepatic cholestasis, and above 30.00 mg/L is severe intrahepatic cholestasis, which is a more serious condition and may affect the fetal amniotic fluid. It may affect the fetal amniotic fluid and cause fetal distress by making the amniotic fluid cloudy, which may lead to fetal death in the womb in severe cases. 2. If the level of glycocholic acid is above 2.70 mg/L, which is higher than the normal value, it is also a more serious case the more serious the symptoms of liver damage or biliary obstruction. Patients with elevated glycocholic acid should maintain a light diet during treatment, avoiding spicy and stimulating, cold and greasy foods, such as chili peppers, crabs and fatty meats, and abstaining from smoking and alcohol. If the state of higher glycolic acid persists, hospitalization for liver-protective and bile acid-lowering treatment is required as soon as possible.
