If a pregnant woman has elevated glutathione aminotransferase, it is most likely due to liver damage, usually a small amount of hepatocyte necrosis or liver insufficiency. In this case, it is important to consider the possibility of viral hepatitis, and if necessary, blood tests for hepatitis B triple system and hepatitis C antibodies are required. If the patient does not have hepatitis, it is usually considered to be a transient liver function impairment, which is seen when the patient is tired and stays up late at night, in addition to the emotional impact on pregnant women can also cause abnormal liver function, including elevated glutamic transaminase. For the above mentioned transient aminotransferase elevation, patients should pay attention to rest, keep a relaxed mood, eat moderate acidic food such as oranges, oranges, grapefruit to supplement vitamin C and pay attention not to get angry, then patients will recover slowly in about 7-10 days. If the patient’s transaminase is elevated above 100U/L and combined with elevated bilirubin, further ultrasound or CT or MRI of the upper abdomen is needed to determine if there is any biliary tract pathology.
