Bleeding from vaginal inflammation is often caused by the following reasons: first, vaginal inflammation caused by trichomonas infection, which causes a large number of bleeding spots in the vaginal mucosa, so that the discharge becomes bloody, and this symptom will disappear soon after active treatment of trichomonas. Secondly, when there is inflammation in the vagina, chronic inflammation may lead to tissue hyperplasia and polyps in the vaginal mucosa, which are relatively brittle and may bleed. This is the cause of bleeding due to vaginal inflammation. It is recommended to actively treat vaginal inflammation and remove the polyps as soon as possible if there is more bleeding.
