What causes bleeding after sex?

The main symptoms of bleeding after intercourse are local and vaginal bleeding during or after sexual intercourse. Generally, the amount of bleeding is not much, but a very small number of people will cause heavy bleeding. However, bleeding after sexual intercourse is mainly a common symptom of gynecological diseases. There are also many people caused by the following reasons. The main reasons are some gynecological diseases, which must be prevented in time in daily life.

The main causes include cervical erosion, cervical polyps, cervical cancer, endometriosis, pelvic cancer and some sexual injuries, mainly some vaginal injuries during sexual intercourse. The main causes of bleeding are very many, mainly due to some organic lesions of the female reproductive system. .

1. Cervicitis (erosion). 90% 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.

2. 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.

3. 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.

4. 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.

5. 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.

The above are the main symptoms and causes of bleeding after intercourse.

6. Sexual intercourse injury. A common site of sexual intercourse injury is the vaginal foramina, which can sometimes cause a foramina several centimeters long. In severe cases, it can reach the peritoneum or penetrate the peritoneum into the abdominal cavity. Some people mistakenly believe that pressing some gauze on the vulva or using some menstrual paper will stop the bleeding, but in fact this does not help. Therefore, if this happens, you need to go to the hospital for examination and treatment as soon as possible. The gynecologist will take appropriate treatment measures according to the specific situation, such as inserting gauze into the vagina for compression or using intestinal sutures to stop bleeding.

The above are the main reasons for bleeding during intercourse. The main reasons include cervical erosion, cervical polyps, cervical cancer, endometriosis, pelvic cancer and some sexual injuries. The main reasons are some injuries to the vagina during sexual intercourse. At the same time, in daily life, we must prevent vaginal bleeding in time, prevent some gynecological diseases and at the same time, we must protect ourselves well.
