Why does a woman bleed after sex?

Generally, female friends will experience vaginal bleeding after their first sexual intercourse. This is normal. It is mainly caused by the tearing of the hymen. There is no need to be too nervous at this time. However, if vaginal bleeding occurs during future sexual intercourse, female friends should be vigilant and seek timely diagnosis and treatment, because there are many diseases that can cause vaginal bleeding after intercourse.

1. Cervical polyps: They are caused by chronic inflammatory stimulation, which causes local hyperplasia of the cervical mucosa and gradually protrudes outward. They are bright red, soft and fragile, and rich in blood. They can be easily broken during sexual intercourse, causing a small amount of bright red bleeding.

2. Cancer: If middle-aged and elderly people experience a small amount of vaginal bleeding after sexual intercourse, which is bright red and painless, and if their vaginal discharge increases recently and has a fishy odor, it is often an early symptom of cervical cancer. You should be vigilant and have a gynecological examination to rule out cancer.

3. Sexually transmitted diseases: A small amount of bright red vaginal bleeding occurs after sexual intercourse, there is recent vulvar itching, and small wart-like growths can be seen on the vulva or vaginal walls; when a man has similar growths on the foreskin of his penis head, genital warts may be considered. Both men and women should go for examination, diagnosis and treatment as soon as possible.

There is also bleeding during pregnancy and bleeding during postpartum period. The former should be treated promptly, and the latter is because the vaginal incision has not yet healed.

In addition, vaginal bleeding is a common symptom of female reproductive organ diseases. Bleeding can come from the vulva, vagina, cervix and endometrium, but most often comes from the uterus. Although vaginal bleeding can be life-threatening, if it is caused by a benign disease, the prognosis is good; and if the amount of bleeding is small, it may also be the earliest symptom of a malignant tumor. If it is ignored, it may delay treatment and cause adverse consequences.

In short, there are generally three types of vaginal bleeding after sex: bleeding during pregnancy, postpartum bleeding, and pathological vaginal bleeding. Each type of vaginal bleeding has its own characteristics. When vaginal bleeding occurs, you should be careful to identify it. It should be noted that patients cannot judge the severity of the disease based on the amount of bleeding.
