There are 3 types of ovulatory dysfunctional uterine bleeding

Ovulatory functional uterine bleeding is a disease caused by abnormal local regulation of the endometrium. Hyperfibrinolysis of the local endometrium makes the thrombus unstable and the endometrial exfoliation lasts; the component ratio of the prostate produced locally in the endometrium is unbalanced, and the ratio of prostaglandin E2 and prostaglandin F2x increases, resulting in a tendency of vasodilation and inhibition of platelet aggregation. Therefore, hemostasis is affected. Ovulatory functional uterine bleeding can be divided into 3 types.

Periovulatory bleeding

After the mature follicle ruptures and ovulates, the estrogen level drops sharply and significantly, which cannot maintain the growth of the endometrium, causing local rupture and shedding of the endometrial surface, resulting in breakthrough bleeding. With the formation of the corpus luteum of the ovary, sufficient estrogen and progesterone are secreted to quickly repair the ruptured endometrial surface and stop the bleeding. Or it is possible that during ovulation, the mature follicles secrete more estrogen, causing endometrial congestion and leakage of red blood cells. It is also possible that when the egg is captured in the fallopian tube fimbria, the blood-containing follicular fluid is sent to the uterine cavity through retrograde peristalsis of the fallopian tube and then flows out of the cervix through the vagina.

Premenstrual bleeding

Also called luteal phase bleeding, bleeding occurs before the basal body temperature drops and lasts for varying numbers of days. After the temperature drops, the amount of bleeding increases like menstruation and stops on time.

Long menstrual periods

If the menstrual period lasts for more than 7 days, or even lasts for half a month, and the menstrual flow is not much, or slightly more than normal, Chinese medicine believes that the main reason for the prolonged menstrual period is spleen and kidney deficiency, Chong and Ren meridians are not solid, or blood heat forces blood to flow indiscriminately; or blood stasis blocks the new blood from returning to the menstrual period. This is the bleeding during the follicular phase, and the bleeding continues for 7 days after the basal body temperature drops.
