Let me analyze it for you below.

Menstrual disorders Among women of childbearing age, the most common cause of bleeding from menarche to premenopause is menstrual disorders. Bleeding caused by menstrual disorders is due to endocrine disorders, and the amount of bleeding can be more or less. This includes functional bleeding in puberty among growing girls and menopausal menstrual disorders before menopause, all of which are caused by ovulatory dysfunction during the menstrual cycle. Even though women of childbearing age ovulate, they may still experience ovulation bleeding: this may be due to poor corpus luteum function or failure to decline in time.

Common causes of vaginal bleeding include:

① Ovarian endocrine dysfunction: including anovulatory uterine bleeding and ovulatory menstrual disorders, as well as uterine bleeding caused by intermenstrual follicle rupture and a temporary drop in estrogen levels.

② Uterine bleeding related to pregnancy: Common ones include miscarriage, ectopic pregnancy, gestational trophoblastic disease (hydatidiform mole, etc.), partial placental retention after delivery, placental polyps and incomplete uterine involution.

③ Genital inflammation: such as vulvar ulcers, vaginitis, cervicitis, cervical polyps and endometritis.

④ Genital tumors: Uterine fibroids are common benign tumors that cause vaginal bleeding. Ovarian tumors that have the function of secreting estrogen can also cause vaginal bleeding. The others are almost all malignant tumors, including vulvar cancer, vaginal cancer, cervical cancer, endometrial cancer, uterine sarcoma, and choriocarcinoma.

⑤ Injury, foreign bodies and exogenous sex hormones: Reproductive tract trauma such as vulva and vaginal straddle injuries, and hymen or vaginal injuries caused by sexual intercourse can all cause bleeding. Uterine bleeding is often a complication of IUD insertion. Improper use of estrogen or progesterone can cause irregular uterine bleeding.

⑥ Vaginal bleeding related to systemic diseases: such as thrombocytopenic purpura, aplastic anemia, leukemia, liver damage, etc., can all lead to uterine bleeding.
