Bleeding after intercourse, sometimes called contact bleeding, is a situation that women often do not encounter, a number of people have asked me about such a situation, today to focus on the science. Bleeding after intercourse a woman of childbearing age, there will be about 6% of the incidence. The bleeding is usually found during or after sexual intercourse and has little to do with menstruation. Some cases of bleeding after intercourse are precursors to certain diseases, and it is important to be alert if they occur. The causes of post-coital bleeding may include: cervical cancer: about 11% of cervical cancer patients may have post-coital bleeding, which may also be the first symptom. Inflammation of the cervix: Inflammation and congestion of the cervix caused by pathogens such as gonococcus, chlamydia, anaerobic bacteria, etc. may lead to contact bleeding, which is usually accompanied by excessive leucorrhea and yellowing. Cervical polyps: usually prolapsed from the cervical canal, the polyps tend to bleed after contact. Cervical tissue is fragile: This is not a diagnosis. The columnar epithelium in the cervical canal, stimulated by estrogen, appears on the surface of the cervix and manifests itself as columnar epithelial ectropion (which many doctors used to diagnose as “cervical erosion”), and contact bleeding may also occur. If you have not had a pap smear for a long time, you are usually advised to have a pap smear. Some pathogens, such as chlamydia, gonococcus and BV, usually require special tests for a definitive diagnosis. Cervical polyps can usually be detected by visual examination by a doctor. Cervical tumors and inflammatory diseases require appropriate professional treatment, while polyps can be removed in an outpatient setting. If tumor, inflammation and polyps are ruled out after examination, no special treatment is needed for other conditions. Cervical columnar epithelial ectropion is a normal physiological phenomenon and does not require any treatment. Therefore, the most important thing is to clarify the cause of bleeding after sex and to treat the cause after understanding the cause. Sorry: Yesterday’s popular article gave a lot of people a shock, perhaps for professional obstetricians and gynecologists these pictures are too common, for you all some bloody stimulation, I will pay attention in the future. In addition, there are some errors in the text that have not been corrected. In addition some professional doctors gave me a reminder to the laceration injury during sex, the stimulation of bleeding after the birth control device, is also a possible cause of bleeding during intercourse. I would like to add this. Happy holidays, everyone.
