The non-doubling of HCG value in pregnancy may be a change in condition caused by preeclampsia, ectopic pregnancy, embryonic abruption, and so on.
1. Pre-eclampsia: After pregnancy, if the pregnant woman has pre-eclampsia, the level of sex hormones in the body decreases, and the HCG value may not double.
2. Ectopic pregnancy: If the gestational sac grows and develops outside the uterine cavity, the HCG value in the body may not increase significantly, which may cause the HCG value not to double.
3. Embryonic arrest: If the chromosomal abnormality of the embryo may cause embryonic arrest, the sex hormones in the body will decline, and the HCG value may not be doubled.
There are many reasons why the HCG value does not double in pregnancy, and you need to be treated according to the cause under the guidance of a professional doctor.
