It is inaccurate to say that transaminase 150 IU/L in pregnant women is not serious at all. If the aminotransferase of pregnant women exceeds 150 IU/L, it indicates that there is a moderate level of elevated aminotransferase, and it is necessary to find the cause of the elevation and carry out targeted treatment according to the trigger. The physiological factors can be relieved after lifting the triggers, while the pathological factors need active medical treatment. 1. External factors: pregnant women’s transaminase 150 IU/L may be caused by excess nutrition, eating too much iron-containing food, or overexertion, drug factors, etc. In this case, patients should be instructed to eat reasonably, stop certain drugs or food if necessary, and review. In this case, the patient should be instructed to eat a reasonable diet, stop certain medications or foods if necessary, have a review to clarify the cause, and follow up with regular observation. Most of the pregnant women with transaminases of 150 IU/L caused by such reasons will return to normal through adjustment, and the impact on pregnant women and fetuses is relatively small; 2. Pathological factors: If pregnant women with transaminases of 150 IU/L are accompanied by weakness, nausea, vomiting and anorexia, pathological factors need to be considered, which may commonly be viral hepatitis, as well as hepatitis B and C. In addition, hypertensive diseases, fatty liver and many other causes may also have a negative impact, There are also many reasons such as high blood pressure disease, fatty liver, etc. that may cause an increase in transaminases. Although the degree of transaminase elevation is moderate at this time, it may be further aggravated and may have adverse effects on the pregnant woman and the fetus, which is more serious. It is recommended to perform liver ultrasound, as well as hepatitis B, C, A and other related viral tests to clarify the cause and then give appropriate treatment.
