What are the reasons for bleeding after sex?

Bleeding after sex is medically called intercourse bleeding. Generally, there is no bleeding after intercourse. Bleeding after sex indicates that the patient has gynecological diseases. Of course, it is necessary to exclude the possibility that the patient has had sex after abortion or after having an IUD. When the patient finds that there is bleeding after sex, he should actively go to the hospital for examination and take treatment after the disease is found. So what are the causes of bleeding after sex?

A little bleeding after sex is a common symptom of gynecological diseases, mainly due to the following reasons:

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.

6. Organic lesions in the female reproductive tract can often lead to bleeding during sexual intercourse. For example, vulvar ulcers can cause friction on the ulcer surface during sexual intercourse, causing pain and bleeding. Vaginitis is caused by the massive shedding of the vaginal epithelium and congestion of the vaginal mucosa. During sexual intercourse, the penis thrusts and rubs in the vagina, causing damage, rupture and bleeding of the vaginal mucosa. The urethral caruncle grows at the female urethral opening. Because of its brittle texture, the slightest touch during sexual intercourse can cause bleeding. Cervical erosion is caused by the exfoliation of the epithelium around the external os of the cervix, which exposes the fragile subcutaneous tissue and forms an eroded surface. During sexual intercourse, the impact of the penis causes bleeding. Due to the infiltration of cancer cells, cervical cancer tissue becomes fragile and often causes contact bleeding during sexual intercourse. The urethra and vagina are adjacent to each other. When the urethra is inflamed, it is easily squeezed and injured during sexual intercourse, causing bleeding.

Women who bleed a little after sex should pay attention to it. If the patient also has other discomfort symptoms at this time, she can go to the hospital for examination and treatment. Of course, the reasons for bleeding a little after sex are very complicated. Bleeding caused by gynecological diseases is one of them. Patients should judge their own symptoms and medical history, which can effectively diagnose the disease and facilitate patients to take correct treatment.
