Therefore, in order to avoid such things, we must grasp the cause of the disease so as to better treat and prevent it. Let’s take a look at the causes of heavy vaginal bleeding.

What causes heavy vaginal bleeding?

Vaginal bleeding refers to bleeding from any part of the reproductive tract, and its bleeding manifestations can be divided into menorrhagia and prolonged menstruation. Irregular bleeding or contact bleeding, etc., the amount of bleeding can be more or less. Vaginal bleeding can be divided into the following categories according to different causes:

Endocrine-related bleeding

Neonatal vaginal bleeding, bleeding related to contraceptive pills, dysfunctional uterine bleeding, intermenstrual bleeding, postmenopausal uterine bleeding, etc.

Pregnancy-related bleeding

Threatened abortion, incomplete abortion, ectopic pregnancy, placenta previa, placental abruption, hydatidiform mole, choriocarcinoma, etc.

Bleeding related to inflammation

1. Vulvar bleeding is seen in vulvar ulcers, urethral caruncle, etc.

2. Vaginal bleeding is seen in vaginal ulcers, vaginitis, especially senile vaginitis, Trichomonas vaginitis, etc.

3. Cervical bleeding is seen in acute and chronic cervicitis, cervical erosion, cervical ulcer, cervical polyps, etc.

4. Uterine bleeding is seen in acute and chronic endometritis, chronic myometritis, acute and chronic pelvic inflammatory disease, etc.

Tumor-related bleeding

1. Irregular vaginal bleeding in young girls is seen in botryoid sarcoma.

2. Vaginal bleeding in middle-aged and older women is often caused by uterine fibroids.

3. Middle-aged or postmenopausal women with contact or irregular bleeding due to cervical cancer, endometrial cancer, functional ovarian tumors, etc.

Trauma-related bleeding

1. The vaginal wall is not fully expanded during first sexual intercourse or the sexual intercourse is too hasty or too violent, which can easily cause vaginal wall tearing. This situation is more common among young girls who have eaten the forbidden fruit. Generally speaking, a woman's vagina is elastic, has many vertical and horizontal folds, is easy to expand, and will not tear. The vagina of a young girl is not yet fully developed. If she is too nervous during her first sexual intercourse, her muscles will contract and she will use too much force, which can easily cause tearing.

2. The vagina of elderly women shrinks and vaginal secretions decrease, which may cause tearing during sexual intercourse.

3. Masturbation: Some women insert their hands or other hard foreign objects into the vagina, causing vaginal rupture.

4. Birth injuries: During delivery, the fetal head descends as the uterus contracts. If labor progresses too quickly, the birth canal has not fully expanded, and the fetus is large, vaginal wall tears are likely to occur.

5. Bleeding caused by trauma.

Because the vaginal wall is rich in blood vessels, continued bleeding can cause serious complications and even be life-threatening.

Bleeding related to systemic illness

Disseminated intravascular coagulation is seen in liver disease, aplastic anemia, thrombocytopenic purpura leukemia and gynecological diseases.

Vaginal bleeding during menstruation

The menstrual volume increases significantly, doubling or even more than the usual amount, accompanied by large blood clots. When standing up suddenly, a large amount of menstrual blood gushes out. In severe cases, symptoms of anemia such as dizziness, blurred vision, and general weakness appear.

Possible causes: bleeding caused by IUD placement, adenomyosis, and ovulatory dysfunctional uterine bleeding.

Vaginal bleeding during reproductive age

Vaginal bleeding during pregnancy in women of childbearing age.

Possible causes: miscarriage, ectopic pregnancy, hydatidiform mole.

Vaginal bleeding near menopause

Possible causes: anovulatory dysfunctional uterine bleeding, malignant tumors.

Spotting before and after menstruation

It lasts for several days, causing the entire menstrual period to last more than ten days or even longer.

Possible cause: Side effects of IUD placement.
