Celiac disease used to be a very disturbing condition for women. In obstetrics and gynecology, the diagnosis of celiac disease has long been eliminated and replaced by cervical columnar epithelial ectasia. In fact, many so-called cervical erosions are not pathological, but a normal physiological phenomenon. So-called cervical erosion is a fine-grained red area in the appearance of the vaginal part of the cervix at the ectocervix. Previously, cervical erosion was also classified into 3 degrees according to the size of the cervical erosion area: mild means that the erosion surface is less than 1/3 of the entire cervical area, moderate means that the erosion surface accounts for 1/3-2/3 of the entire cervical area, and severe means that the erosion surface accounts for more than 2/3 of the entire cervical area. If the cervical erosion is only due to hormonal influence, the squamous epithelium outside the cervical opening and the columnar epithelium inside the cervix are displaced at the junction, because the columnar epithelium is thinner, so it will reveal the blood vessels below and appear redder, this is a normal phenomenon, do not worry at all. If it is indeed caused by inflammation of the cervix, there are corresponding treatments. Cervical erosion may be a normal physiological phenomenon, and it is not necessarily related to cervical cancer, so there is no need to worry too much, but regular cervical examinations are needed.
