The first thing to look at is the source of the bleeding, which most often occurs in the cervix. Therefore, cervical problems need to be ruled out. If you have not had cervical cancer screening for a long time, you need to have a pap smear first to exclude cervical tumor problems, and if the pap smear screening reveals problems, you need targeted diagnosis and treatment. If there is inflammation, the inflammation needs to be treated. For frequent bleeding after sex caused by inflammation, physical therapy such as laser can also be used. If there are cervical polyps present, they need to be removed. Bleeding from inflammation or other lesions of the vagina needs to be examined and treated accordingly. Bleeding from the uterine cavity is also occasionally encountered. Therefore, the key to bleeding after sex is to check the cause of the problem and treat it accordingly.
