Indirect bilirubin, also known as unconjugated bilirubin, is mainly produced by the destruction of red blood cells through hepatic metabolism and refers to bilirubin that has not been glucuronidated in the liver. Generally, high indirect bilirubin has clinical significance, while low indirect bilirubin is not clinically significant if there are no other abnormal test results or uncomfortable symptoms. If a pregnant woman has low indirect bilirubin, she may suffer from some liver diseases, such as hemolytic jaundice, obstructive jaundice, hepatocellular jaundice, etc. Such diseases may damage the liver to varying degrees, thus reducing the synthesis capacity of the liver and preventing the normal and timely conversion of indirect bilirubin, which may lead to low indirect bilirubin in pregnant women. When a pregnant woman has low indirect bilirubin, it is recommended to go to the hospital for an upper abdominal ultrasound or CT to clarify the cause and then carry out the corresponding symptomatic treatment. At the same time, you should do regular review, scientific and reasonable nutrition, and pay attention to a light diet, ensure a regular life, happy spirit, and appropriate activities, and do not take medication without authorization. It is advisable to rest in bed for 1-2 hours after meals to ensure that the liver gets sufficient blood supply, which is conducive to liver cell repair.
