Sudden vaginal bleeding is a common problem faced by many women. Some of it is physiological vaginal bleeding, such as normal menstruation and postpartum lochia, which are within the normal physiological range and will not harm your health. Pathological vaginal bleeding is different. It is not only a manifestation of physical illness, but the bleeding itself can also damage physical health. Vaginal bleeding can come from the vulva, vagina, cervix, and endometrium, but most cases come from the uterus.

There are many reasons for abnormal sudden vaginal bleeding, such as: ovarian endocrine dysfunction, abnormal pregnancy, tumors, reproductive tract inflammation, injury, foreign bodies, or systemic diseases. Age is an important reference value for the identification of vaginal bleeding: vaginal bleeding in young girls and postmenopausal women (elderly women) is often considered to be malignant tumors; vaginal bleeding in adolescent women is first considered to be dysfunctional uterine bleeding (abbreviated as functional uterine bleeding); and women of childbearing age are often considered to have pregnancy-related diseases.

Vaginal bleeding can be roughly divided into the following types:

1. The menstrual volume increases and the menstrual period is prolonged but the cycle is normal. It may be uterine fibroids, adenomyosis, or dysfunctional uterine bleeding. In addition, those who have used an intrauterine device may also have increased menstrual flow.

2. Irregular vaginal bleeding during the menstrual cycle is often functional uterine bleeding, but endometrial cancer should be ruled out first.

3. Long-term continuous vaginal bleeding is mostly caused by malignant tumors of the reproductive organs, such as cervical cancer, endometrial cancer, etc.

4. Irregular bleeding after menopause. Women of childbearing age are more likely to be concerned about pregnancy-related diseases, such as miscarriage, ectopic pregnancy, hydatidiform mole, etc.; postmenopausal women are more likely to have malignant tumors.

5. Bleeding after sexual intercourse is mostly caused by cervical erosion, cervical polyps, cervical cancer or submucosal myoma.

6. Vaginal bleeding accompanied by leucorrhea is often considered to be advanced cervical cancer or endometrial cancer with infection.

7. Paroxysmal vaginal bleeding may indicate primary fallopian tube cancer.

8. Intermenstrual bleeding occurs between two menstrual periods, lasts for 3-4 days, and when the amount of blood is very small, it is mostly ovulation bleeding.

9. Spotting before and after menstruation, and a small amount of bloody discharge a few days before or after menstruation, are generally caused by abnormal ovarian function and may also be endometriosis.

The above is an introduction to what causes sudden vaginal bleeding. I believe that after reading the above introduction, you already know what sudden vaginal bleeding is. From the above introduction, we can see that sudden vaginal bleeding is normal if it is menstruation. If it is caused by a disease, you need to go to the hospital in time so that you can receive symptomatic treatment.
