High liver function transaminases in pregnant women may be due to physiological reasons, or may be caused by drugs, viral infections and other factors. 1. After pregnancy, the burden on the pregnant woman’s liver increases, which may lead to mild elevation of aminotransferases. In this case, there is generally no need to worry too much, and there is no need to take medication, so just pay attention to regular monitoring of liver function. 2. If pregnant women take progesterone and progesterone in the early stage of pregnancy, it may lead to drug-induced hepatitis, which may result in high liver transaminases. 3. If the pregnant woman herself is infected by viruses such as hepatitis B virus, cytomegalovirus, herpes virus, rubella virus, etc., it will lead to inflammation of the liver, which will lead to high liver transaminases. Women are advised to go to the hospital, complete the relevant examinations, clearly diagnose the cause of the disease, and then intervene in the treatment as soon as possible to avoid adverse consequences.
