Thin endometrium means that when the follicle develops and matures (in the middle of menstruation), the thickness of the endometrium cannot reach 8mm when gynecological ultrasonography is performed, which may affect the amount of menstruation and the implantation of fertilized eggs, causing infertility or early miscarriage. If it is caused by endocrine disorders resulting in low estrogen and progesterone levels, estrogen and progesterone drugs should be applied to regulate, because estrogen and progesterone are the driving force for the growth of the endometrium, and estrogen can prompt the endometrial epithelium and mesenchyme to show a proliferative state, and progesterone can make the endometrium show a secretory response; for the endometrial damage and adhesion resulting from repeated medical abortions and multiple purges, attention should be paid to contraception to reduce the risk of abortion and medical abortion on the endometrial lining. For the endometrial damage and adhesion caused by multiple abortions, we should pay attention to contraception, reduce the damage to the endometrium caused by abortion, drug abortion, and carry out hysteroscopy to check the endometrium if necessary; for endometritis caused by endometritis, we should treat inflammation first. In addition, the motherland medicine also has acupuncture, traditional Chinese medicine, moxibustion and other methods, the effect is also good. To treat endometrial thinning, it is necessary to check the level of sex hormones at the same time, to determine the cause of the disease, because the treatment of endometrial thinning caused by different factors is different, so it is necessary to give targeted, individualized treatment.
