Normal estradiol levels at 4 weeks of pregnancy

Estradiol is the most important hormone in estrogen. It can promote the proliferation of the endometrium and the development of mammary ducts. The content will change with the menstrual cycle. Too low estradiol during pregnancy cannot create a good environment for conception, which is not conducive to the growth and development of the fetus and may also cause miscarriage. It is very necessary to check the estradiol hormone during pregnancy. The estradiol value at four weeks of pregnancy is 0-300ng/L. If the level is too low, the fetus will not develop well. If the test results are not within the normal range, you need to use medication to supplement estradiol under the guidance of a doctor. Do not supplement it without authorization.

The amount of estradiol varies throughout pregnancy, rising slightly in normal pregnancy and dropping sharply after the placenta is delivered. In the early pregnancy, it is generally 0-300ng/L, in the mid-pregnancy, it is generally 1000-8000ng/L, and in the late pregnancy, it is generally 5000-27000ng/L.

What are the dangers of low estradiol levels?

Generally speaking, as long as there is no bleeding after pregnancy and the B-ultrasound shows that the embryo is developing normally, there is no need to delve too deeply into the specific content of estradiol. However, sometimes low estradiol levels are a precursor to certain serious diseases, such as ovarian dysfunction, premature ovarian failure, Sheehan's syndrome, etc., which require attention.

In fact, when it comes to estradiol, many friends may not be very familiar with this term. However, as a very important hormone in the female body, it has the function of promoting and regulating the normal development of female reproductive organs and secondary sexual characteristics. It is mainly secreted by the follicles after the ovaries mature.

Every woman pays special attention to her physical health. Once there is something wrong, for the sake of health, it is recommended that you go to the hospital for detailed examination and treatment in time. Only by further examination and treatment can other diseases be prevented. Of course, if the disease is under control, pregnancy will be much easier.
