High leucine aminopeptidase in pregnant women may be a normal phenomenon or an abnormal phenomenon caused by disease, which can be regulated and treated by adjusting diet and medication. Common causes and treatments I. Normal phenomenon: high leucine aminopeptidase in pregnant women may be due to the increase in pregnancy, the body’s hormone level changes, liver cells gradually proliferate, and then show high leucine aminopeptidase, often after delivery back to normal. Second, abnormal phenomenon: 1, hepatitis: if pregnant women suffer from hepatitis, in the liver function examination, there may be high glutamic aminotransferase, glutamic oxalacetic aminotransferase, leucine aminopeptidase. If you get hepatitis in early pregnancy, hepatitis in this period can easily lead to fetal malformation, and may transmit the virus to the fetus, and may turn into severe hepatitis and endanger the life of the pregnant woman, so from the perspective of eugenics, it is recommended to end the pregnancy as appropriate. If you have viral hepatitis in the middle and late pregnancy, you should consider whether to keep the fetus according to the type and degree of viral hepatitis; 2. cirrhosis: laboratory tests are elevated serum bilirubin, reduced albumin, high leucine aminopeptidase. Pregnant women with cirrhosis should pay attention to review, monitor the condition of cirrhosis and fetal status at any time, clarify the cause of cirrhosis and treat the cause; 3. Pregnant women with benign liver tumor can continue pregnancy under close observation. For patients with malignant liver tumor, termination of pregnancy needs to be considered to treat liver cancer. General treatment of liver cancer usually adopts surgical radical treatment, together with interventional chemotherapy and local radiotherapy, etc.; 4. Cholestasis syndrome: it can be manifested as high leucine aminopeptidase, jaundice, diarrhea, pain in liver area, etc. It is recommended to treat with Chinese medicine to tonify the kidney and dispel dampness, strengthen the spleen and help transport, and clear heat and dredge the liver. In this case, the patient should be hospitalized promptly and under the guidance of the doctor, comprehensive treatment should be actively carried out by draining bile and other methods; 6. Breast cancer: high leucine aminopeptidase can be seen on examination and can be further determined by chest ultrasound. For pregnant women with breast cancer may need to terminate pregnancy and actively treat breast cancer to prolong life expectancy and improve survival quality.
