Cervical polyps can cause bleeding, but not every day, bleeding occurs mostly after sex, between menstruation, straining to defecate and so on. 1. After sex: Because cervical polyps usually grow on the surface of the cervix, they are more vulnerable to long-term stimulation, and it is easy to rub the polyps many times during sex, resulting in damage to the mucous membrane, and thus bleeding occurs. 2. Between menstruation: because between menstruation, cervical polyps may appear inflammatory lesions, causing mucosal congestion and edema, bleeding can also occur. 3. Bowel movement: If there is constipation or poor bowel habits, resulting in increased pressure in the abdominal cavity, it is easy to stimulate the mucosa of the polyp, bleeding occurs. Cervical polyps usually bleed in the above cases, but generally do not bleed in other cases. If bleeding occurs every day, you need to go to the hospital in time for examination and standardized treatment.
