Why is there blood after sex?

Some women experience vaginal bleeding after having sex, which may not stop and is accompanied by lower abdominal pain. They don’t know what is going on, and many people are scared, worried and terrified, not knowing whether to go to the hospital. In fact, vaginal bleeding after intercourse can be a major or minor gynecological problem. It may be caused by abrasions of the vaginal wall or by gynecological diseases. Below I will tell you what are the causes of bleeding.

Reason 1: Cervical erosion

Cervical erosion is the most common manifestation of chronic cervicitis. The cells in the eroded area of ​​the cervix are very easy to fall off and become thinner, so some women with cervical erosion are most likely to find bleeding after having sex.

Reason 2: Cervical polyps

Cervical polyps are mostly tongue-shaped, about the size of a sunflower seed, often protruding outside the cervical opening. They can be single or multiple in number, soft in texture, and bright red in color. The top of the polyp has loose tissue and rich blood vessels. When some polyps become edematous, gangrenous, and infected, their appearance may be similar to that of early cervical cancer, and they may easily cause bleeding after intercourse. Cervical polyps are generally benign lesions and rarely become malignant. Therefore, the diagnosis and treatment of cervical polyps cannot be ignored.

Reason 3: Cervical cancer

Bleeding during sexual intercourse is often a dangerous sign of early cervical cancer. The amount of bleeding is not much and the color is bright red. However, if it is early-stage cervical cancer, the amount of bleeding may increase, and even blood clots may flow out. This is because the cancerous cervical cell tissue has become eroded and brittle, and the affected area has a good blood supply, so when the cervix is ​​directly hit, it will rupture and cause bleeding.

Reason 4: Vaginitis

Common ones include Trichomonas vaginitis and candidal vaginitis. Due to the invasion of pathogens such as Trichomonas or fungi on the vaginal wall and cervical tissue, it manifests as severe edema. The vaginal wall of trichomoniasis may have scattered bleeding spots or strawberry-shaped protrusions, while the vaginal wall of candidal vaginitis may be erosive or superficial ulcers.

In addition to the above symptoms, it may also be caused by irregular menstruation, premature sexual intercourse, which causes uterine contraction under sexual stimulation, and the residual blood in the uterine cavity is discharged from the vagina. So now that you know the reason for bleeding, there is no need to be confused. Female friends should understand that their health should not be underestimated.
