For pregnant women, progesterone and HCG are important health evidence used to determine whether the pregnant woman and fetus are healthy. Therefore, daily test values are very important. If there is a doubling of HCG but a decrease in progesterone, it is necessary to promptly understand the situation and see if it will have an impact on the fetus and pregnant women. So, is it normal for progesterone to decrease and double HCG?

In fact, it is abnormal for progesterone to decrease and double HCG, but the cause needs to be identified and targeted regulation and treatment should be carried out.
1. Indicating that the pregnant woman's body hormones are abnormal
After pregnancy, if the pregnant woman's hormones are insufficient, progesterone will be abnormal. Especially in the early stages of embryonic development, it is necessary to check the values of estrogen, progesterone, and HCG to determine whether the fetus is healthy. If pregnant women have insufficient endogenous hormones, the results of progesterone testing will also decrease, which may lead to the consequences of embryo miscarriage. If the value is not within the normal range, it is necessary to seek medical attention in a timely manner.
2. Indicating that embryos may exhibit abnormal conditions
If pregnant women or fetuses have health problems, it can lead to a continuous doubling of HCG, but progesterone will suddenly decrease. At this time, it is necessary to promptly investigate the cause and take measures to prevent miscarriage.
3. There are also abnormal conditions in the thyroid gland of the body
If there is a severe imbalance in the body's adrenal hormones and thyroid function. At this time, pregnant women's bodies may also experience a decrease in progesterone levels due to diseases, which can affect their ovarian function and lead to insufficient corpus luteum secretion. However, this situation is relatively rare, but once it occurs, it is important to improve and control the thyroid gland in a timely manner to avoid serious consequences.
