Patient's question:
Does hCG decrease after a missed miscarriage?Doctor's answer:
After fetal demise, blood HCG will definitely decrease. Currently, after fetal demise, there is no source of HCG secretion, leading to a decline in blood HCG levels. However, if the pregnancy has lasted more than 70 days, since HCG has already peaked, it will naturally decrease under normal circumstances. But if it is a teratoma or a trophoblastic disease, blood HCG will not decrease.
