Cervical polyps bleed easily during pregnancy due to their rich blood supply, and those who bleed repeatedly need to undergo removal as prescribed by the doctor. Cervical polyps are a manifestation of chronic cervical inflammation, due to the formation of localized hyperplasia of the glands and mesenchyme of the cervical canal. As a result of long-term inflammatory stimulation, polyp tissue is brittle and easy to bleed. After pregnancy, due to localized congestion of the cervix, the polyp tissue has a rich blood supply, which is more likely to cause bleeding, manifested as recurrent vaginal bleeding during pregnancy, without abdominal pain. Cervical polyps can be diagnosed by ultrasonography and gynecological examination. Cervical polyp removal is recommended in cases of recurrent bleeding during pregnancy to avoid increased risk of infection. During the operation, gauze should be given to stop bleeding by local pressure, and if necessary, Yunnan Baiyao and other drugs should be given to stop bleeding locally, and the removed tissues should be sent to pathology for examination. After the operation, we should pay attention to personal hygiene and keep the vulva clean and dry.
