What causes vaginal bleeding after sex?

What disease causes vaginal bleeding after intercourse? Many female friends experience vaginal bleeding after intercourse. Because they are busy with work, female friends usually simply wash their vulva with clean water after intercourse bleeding and go to sleep. They go directly to work in the morning and have no time to take care of this problem. However, you should know that this will bring hidden dangers to your health. Let’s take a look at what disease causes vaginal bleeding after intercourse.

1. Symptoms of vaginal bleeding after sex

Generally speaking, normal and coordinated sexual life will not cause vaginal bleeding in women. Vaginal bleeding after intercourse often indicates the presence of some pathological condition. Vaginal bleeding is a common gynecological symptom. Blood flows out of the vagina, but the bleeding site may be the vagina, cervix or uterus (the latter is more common); the amount of bleeding varies (a few are in the form of drops, and a lot can be life-threatening); the bleeding situation varies (it can manifest as menstrual disorders, irregular bleeding, or contact bleeding after sexual intercourse, after a gynecological examination, etc.).

2. External genital tract injury

Damage to the hymen. The most common is rupture of the hymen during first sexual intercourse. This bleeding usually occurs during sexual intercourse. There may be pain and bleeding at the time, but the amount of bleeding is usually not much. If the injury is not serious, the bleeding will stop soon. However, sometimes when the rupture of the hymen happens to damage the blood vessels in that area, bleeding is heavy and requires pressure to stop the bleeding (such as using a clean cotton ball or gauze, a clean towel, etc.), or even going to the hospital for treatment.

3. Vaginal laceration

Vaginal bleeding occurs during or after sexual intercourse and the amount of bleeding is heavy, difficult to stop on its own, and lasts for a long time. Vaginal lacerations often occur during involuntary sexual intercourse or very rough sexual intercourse. Vaginal lacerations are also seen in vaginal malformations, such as vaginal septum, transverse septum, double vagina, and vaginal stenosis. If the vaginal wound heals poorly after vaginal plastic surgery, hymen repair, vaginal tumor removal surgery, or hysterectomy, sexual intercourse may easily cause damage. Improper sexual posture and position can also cause vaginal injury and bleeding. The amount of bleeding depends on the location and extent of the injury. There was a woman who, after being raped, suffered severe lacerations from the posterior vaginal wall to the vaginal vault and suffered heavy bleeding. She went to the hospital six hours later. When she did, she had already shown signs of hemorrhagic shock, including pale complexion, rapid pulse, and low blood pressure.

4. Cervical polyps

Chronic inflammation may cause cervical polyps due to long-term stimulation of the cervix. Single or multiple small pedunculated granulation tissues grow at the cervical opening, looking like bean buds, and the larger ones are as big as a finger. Polyps are fragile and tender, and will bleed if touched, so bleeding may occur after sexual intercourse. This bleeding is usually bright red.

5. Cervical cancer

Bleeding after sexual intercourse is the earliest symptom. Because there are more small blood vessels and the tissues are more fragile in the cancer lesions, the capillaries will rupture and bleed due to damage after each sexual intercourse. If the cancer grows further, it will bleed more easily.

6. Endometriosis

Some endometriosis grows on the cervix and appears as blue-purple nodules. If this blue-purple ectopic nodule is touched during sexual intercourse, it will cause bleeding. The amount of bleeding is generally small and dark red, and abdominal pain often occurs after intercourse.

7. Pelvic Inflammatory Disease

Pelvic inflammation can cause pelvic congestion. If the endometrium is congested and edematous, sex may cause the congested endometrium to release hormones, but this opportunity is rare.

8. Cervicitis

Ninety percent of married women suffer from cervicitis. Cervicitis is divided into three types: mild, moderate and severe according to the degree of cervical erosion. For patients with moderate or severe cervical erosion, the rubbing of the cervix by the glans of the male's penis during sexual intercourse may cause injury and bleeding. Because the amount of bleeding is small, it does not flow out immediately but accumulates in the vagina, and the color of the blood changes from fresh to old. Therefore, when the blood flows out the next day, it is dark red.

The above is an explanation of what disease causes vaginal bleeding after intercourse. Female friends who have experienced this phenomenon must pay attention to it and see whether vaginal bleeding after intercourse is caused by vaginal damage due to excessive force in sexual intercourse or by certain disease factors. It is best to go to the hospital for a check-up in time to clarify the cause of this phenomenon to avoid untimely discovery of the disease and increase the difficulty of cure.
