Will hcg decrease if the fetus stops growing?

The occurrence of fetal arrest is actually very likely to result in miscarriage, which is a very common phenomenon in life, but many mothers do not understand this kind of knowledge. After fetal growth retardation, the mother's hcg will decrease accordingly. This is also a normal chain reaction. Therefore, if the body's hcg decreases, you should seek medical attention in time.

How long does it take for hcg to drop after the pregnancy stops?

Fetal arrest is also called fetal growth arrest. The fertilized egg is considered complete only when it gradually grows and develops into a healthy baby. When the embryo dies at a certain stage of development and stops developing, it is called fetal growth arrest. Under normal circumstances, the hcg level in the blood will not drop immediately after fetal arrest. It usually takes 10-14 days to drop to normal levels.

How much hcg decreases indicates fetal arrest

HCG is the abbreviation of human chorionic gonadotropin. First of all, we need to understand the reference index range of each stage of HCG

Normal early pregnancy blood hcg level (the following units are all IU/L):

HCG within 1 week: 5~50.

1 to 2 weeks HCG: 50~500.

2 to 3 weeks HCG: 100~5000.

3 to 4 weeks HCG: 500~10000.

4 to 5 weeks HCG: 1000~50000.

5 to 6 weeks HCG: 10,000~100,000.

6 to 8 weeks HCG: 15,000~200,000 (gradually decreases after 8 weeks and maintains stability).

HCG from February to March: 10,000~10,000 (remains stable until after delivery, when it drops again and disappears).

If hcg drops significantly within the first 8 weeks and does not reach the average level, it may indicate fetal arrest or threatened abortion. In addition, the hcg level in early pregnancy increases at a doubling rate, and the highest can soar to 100,000 to 200,000. The specific values ​​will be different depending on the decrease in hcg that occurs in different periods. Generally, if it is about 60% lower than the normal value, fetal arrest may be highly suspected. However, we cannot rely solely on hcg to determine whether there is fetal arrest or threatened abortion. A complete B-ultrasound examination is also needed to determine whether the fetal bud or fetal morphology in the gestational sac is incomplete, whether there is fetal heartbeat, or whether there is a fetal bud.

After reading the editor’s article about “How long will it take for hCG to drop after fetal arrest”, I believe everyone has a comprehensive understanding of hCG. At the same time, parenting experts kindly remind you: During pregnancy, female friends should maintain a stable mentality and not be too anxious, as this will be bad for both the fetus and themselves; follow the doctor's advice, do not take fetal nourishing or fetal preserving drugs indiscriminately, and go to the hospital for prenatal check-ups on time.
