How old are you? If you are peri-menopausal, no need to worry. If you are in your 20s or 30s, you should check with your gynecologist. Functional uterine bleeding, referred to as dysfunctional uterine bleeding, is a non-organic lesion of abnormal uterine bleeding caused by abnormal neuroendocrine disorders caused by abnormal regulation of the hypothalamic-pituitary-ovarian (H-P-O) axis. Gongxue is a common gynecological disease, accounting for about 10% of gynecological outpatients. Clinically, the disease is divided into two types, namely, anovulatory dysfunctional uterine bleeding and ovulatory dysfunctional uterine bleeding. The former, often occurs in adolescent and menopausal transitional women. Adolescent functional uterine bleeding is due to delayed development of the neuroendocrine center or delayed maturity. The dysfunctional uterine bleeding in postmenopausal women is mainly due to the hypofunction of the hypothalamic-pituitary-ovarian axis, which is caused by the continuous decline of ovarian function.
