What is the reason for endometrial shedding during non-menstrual period?

Endometrial shedding is a condition in which the patient ovulates during the menstrual cycle. However, due to incomplete follicular development and good corpus luteum development, the atrophy process is prolonged, which causes the endometrium to fail to shed as scheduled. The menstrual period is significantly prolonged, which can be as long as 10 days. This is called irregular endometrial shedding and is a type of ovulatory dysfunction. Uterine bleeding is more common during the reproductive period and often occurs after miscarriage or full-term delivery. Abnormal uterine bleeding is a condition in which the patient has a normal menstrual cycle, but the menstrual period is prolonged, lasting up to 9 to 10 days, and the amount of bleeding is heavy, and it may even last for several days before stopping.

Endometrial shedding is common in uterine fibroids, especially submucosal fibroids. Even small fibroids can cause menorrhagia, followed by adenomyosis and pelvic endometriosis. Due to the growth of the endometrium into the uterine muscle wall and the enlargement of the uterus, the menstrual volume is often large. The clinical manifestations are abnormal uterine bleeding. The patient's menstrual cycle is normal, but the menstrual period is prolonged, up to 9 to 10 days, and the bleeding is large, and even bleeding for several days before stopping. Auxiliary examinations show that there is still a secretory phase when the endometrial pathology examination is taken on the fifth day of regular menstruation. The basal body temperature is biphasic, but the menstruation slowly decreases after rising or the menstrual progesterone level does not decrease. In addition to the typical clinical manifestations, the basal body temperature is biphasic, but it decreases slowly. Diagnostic curettage is performed on the 5th to 6th day of the menstrual period. The endometrial biopsy can still see the endometrium with secretory reaction, and it coexists with the bleeding phase and the proliferative phase.

There are two types of physiological and disease-related non-menstrual vaginal bleeding: Generally speaking, women will experience ovulation bleeding during the ovulation period, that is, mid-menstrual bleeding, which refers to a small amount of bleeding between two normal menstrual periods, which may be accompanied by varying degrees of lower abdominal pain. If the symptoms are mild, no treatment is required. People with excessive bleeding or those who affect fertility can use medication to treat irregular vaginal bleeding. When women experience non-menstrual bleeding, the first is ovulation bleeding. Usually, ovulation bleeding occurs about two weeks before the next menstrual period. And this amount of bleeding is relatively small, usually only the leucorrhea turns red.
