1, with age, every woman will enter menopause, and women after menopause estrogen levels decrease, this is an inevitable physiological process. So low estrogen levels in older women are a normal phenomenon, and we shouldn't worry too much about it.
2, pathologically low estrogen is likely to be caused by some systemic diseases, the most common clinical is polycystic ovary syndrome, polycystic ovary syndrome will make women's endocrine hormone secretion imbalance, which will lead to estrogen secretion is too low. Diabetes can also lead to hormones in the ovaries and gonads because of vascular disease, making the gonads function further down, which in turn can lead to a further decline in estrogen levels.
3, now is a thin for the beauty of the times, many young women in pursuit of a slim figure, usually adhere to excessive dieting, which will not only make their own nutritional intake is insufficient, and will make the subcutaneous fat content is very small, resulting in the body of estrogen synthesis is reduced. In addition, if a woman's hypothalamus, pituitary gland and ovary axis function abnormally, it will also lead to endocrine dysfunction, resulting in a decrease in estrogen levels.
The reason for low estrogen is the three points described above, first of all, after menopause, estrogen levels will naturally decline, which is a normal physiological phenomenon, if a woman has polycystic ovary syndrome or diabetes, to a certain extent, it will affect estrogen, and finally, if the subcutaneous fat content is relatively low, or the pituitary ovary axis of the woman's function is abnormal, it will also lead to a decline in estrogen.
