Estrogen is an important substance for the development of female secondary sex characteristics as well as the maturation of the genitals. Low estrogen can easily cause delayed development of the vagina and the adnexa as well as incomplete development, and even infertility, and clinically there are dietary treatments and medications to enhance estrogen, as well as other glandular treatments for a combination of therapies. If estrogen is low, it can be improved through dietary therapy, which is called qi and blood deficiency or kidney deficiency in Chinese medicine. You can increase foods rich in selenium and zinc, such as various kinds of fish, kelp, sesame seeds, eat more lean meat, milk, foods containing vitamin D to balance hormones and raise the index, and also regulate the endocrine system. If the estrogen level is low for a long time, you can take Chinese medicines or western medicines to raise the hormone level, such as Wu Ji Bai Feng Pills, Donkey Gum Blood Replenishing Pellets, Estradiol Valerate Tablets, or direct injection of artificially extracted estrogen. If the low estrogen level is more serious, it is recommended to check whether the ovaries and other glands are diseased, and a general laparoscopy can confirm the diagnosis. Estrogen is one of the most important hormones for women’s health and should be diagnosed, treated and supplemented at an early stage, otherwise it will aggravate the load on the glands. It is important to observe the amount of menstruation, whether the menstruation is accurate or not, to eat regularly and pay attention to work and rest time, and to take some vitamin supplements, which will help to improve the secretion of the glands.
