Women who have had pregnancy experience are not unfamiliar with HCG. Generally, doctors in early pregnancy will have pregnant women regularly check their blood HCG levels to determine the quality of fetal development. Under normal circumstances, the HCG level in the pregnant woman's body will increase after conception, stimulating the development of the corpus luteum to maintain the nutrients for pregnancy. Will HCG continue to increase normally after fetal cessation?
Generally speaking, after the fetus stops developing, the HCG value of pregnant women will not immediately stop, and there is still a possibility of a slight increase, but the magnitude of the increase will be relatively small. Because embryonic arrest refers to the absence of a fetal heart in the gestational sac, in the absence of a fetal heart, the trophoblast cells may still proliferate in the short term, so the HCG value will still increase, but this increase generally does not last for a long time.
Generally, there will be a decrease in HCG within 3-5 days or up to a week. Therefore, if the embryo is just found to have stopped developing and tested for HCG, an increase in HCG will be observed. However, it is important to pay attention to whether there is a decline in the later stage and to combine it with ultrasound to determine whether there is embryonic arrest. If embryonic arrest has been diagnosed based on ultrasound or pregnancy time. Even if HCG is rising, it is useless and abortion must be performed.
There are many reasons for miscarriage in pregnant women, the most common of which is placental dysplasia. Once the placenta develops poorly, the fetus cannot receive nutrition and cannot grow. If the embryo itself is deformed, fetal arrest is also inevitable. Another situation is that the abnormal secretion of certain important hormones in the pregnant woman's body can also cause the fetus to stop developing.
