What causes vaginal bleeding after sex?

After sexual intercourse, many women will experience severe bleeding symptoms in their vagina, which is harmful to women. Is it vaginal bleeding or uterine bleeding? Unexplained bleeding can easily lead to symptoms such as infection. Let’s analyze what causes vaginal bleeding after sex?

Caused by pelvic and vaginal inflammation

For example, cervical erosion can cause bleeding during sexual intercourse; people with cervical polyps may also experience vaginal bleeding after straining to defecate. Young children with vaginitis may also have a small amount of vaginal bleeding. Patients with senile vaginitis often have bloody leucorrhea and are accompanied by vulvar itching and pain.

Vaginal tumors

Tumors of the vaginal wall, such as vaginal cancer, but usually the amount of bleeding is not much. Vaginal injury and foreign objects in the vagina can also cause bleeding. The vaginal walls of postmenopausal women are very thin, and damage from sexual intercourse can lead to bleeding.

Cervical cancer

Cervical cancer can also cause bleeding, which starts as contact bleeding and later develops into a small amount of irregular vaginal bleeding. In the late stage, the amount of bleeding increases, and even heavy bleeding may occur.

Uterine lesions

Acute endometritis causes congestion and edema of the endometrium, and in severe cases, it can lead to excessive menstrual flow or continuous vaginal bleeding. Patients with chronic endometritis may experience increased menstrual flow or prolonged menstrual periods, or irregular vaginal bleeding. In addition, endometrial tuberculosis also causes irregular vaginal bleeding.

Dysfunctional uterine bleeding

It occurs around puberty, during the reproductive years, and around menopause. It manifests as abnormalities in the menstrual cycle and menstrual period, with bleeding that may be more or less, sometimes absent, or even continuous.

Foreign bodies in the uterine cavity

If the fetal membrane remains after cesarean section, it will affect the contraction and repair of the endometrium and cause bleeding. Mechanical compression of the intrauterine device can cause local damage, necrosis and superficial ulcers in the endometrium, leading to bleeding. Endometriosis and adenomyosis may also cause bleeding.

The above is what causes vaginal bleeding after sex. When you also experience such symptoms, you should consider whether the symptoms are caused by any of the above reasons. Only after finding the cause can the disease be treated in time. I hope the above information can be helpful to you.
