Cervical polyps are a common condition in obstetrics and gynecology and can be caused by a variety of factors. First, local inflammatory irritation in the vagina can cause cervical polyps. Local inflammation in the vagina can cause proliferation of cervical epithelial tissue, which can lead to the formation of polyps. In this case, the polyp tissue is bad and brittle and bleeds easily when touched. Secondly, increased estrogen levels in the body can also lead to the formation of polyps. With high levels of estrogen in the body, the cervical columnar epithelium migrates outward, promoting the proliferation of cervical epithelial tissue and the formation of polyps. There are also specific conditions that can lead to the formation of polyps in the cervical or vaginal stump. For example, in patients with a history of previous cervical surgery, during the process of repairing the cervical tissue after surgery, there is hyperplasia, etc., which forms cervical polyps in the naked eye. In some patients with total hysterectomy, the tissue of the vaginal stump reacts to the absorbable vaginal sutures with rejection, which can cause the formation of local polyps in the vaginal stump under the stimulation of the sutures. Thus, the etiology of cervical polyps is diverse. It is difficult to prevent the occurrence of polyps completely. Therefore, regular gynecological check-ups are particularly important.
