Also known as AFU, the presence of a woman with high levels of lyase after pregnancy is not caused by any disease, but is a normal response to elevated hormone levels after pregnancy. Lysosomal acid hydrolase, which is significantly increased during non-pregnancy, is used as a diagnostic aid in the diagnosis of primary liver cancer. If a woman has only a mildly elevated lysosomal acid hydrolase after pregnancy, she can be retested after 7 days. As long as she does not have abnormal liver function or abnormal liver masses, she can observe first and the lysosomal hydrolase will be more normal 4-5 days after delivery. Women should also increase nutrition and exercise appropriately during pregnancy to help the metabolism of all body organs and prevent pregnancy-related diseases.
