Cervical erosion is a physiological and morphological change of the cervix that does not require treatment and can recover on its own. Usually diagnosed during gynecological examinations, “celiac disease” is now called “cervical columnar epithelial ectasia”, which is a physiological phenomenon. This is a physiological phenomenon that is caused by changes in hormone levels in the female body. In the cervix, there are two different types of cells: squamous epithelial cells near the vagina and columnar epithelial cells near the uterus. The part of the cervix seen during a gynecological examination is the part of the cervix covered by columnar epithelial cells, while the relatively smooth outer part is the part of the cervix covered by squamous epithelial cells. The two types of cells are in a dynamic equilibrium, and this area is medically named the “squamous-columnar junction area”, which is easily affected by estrogen. Before puberty, estrogen is low, the cervical columnar epithelium on the inside; after menarche, under the influence of estrogen, the columnar epithelial cells more towards the outside, so the cervical examination will find similar to the “vesicles” like columnar epithelium. After menopause, estrogen levels decline, the columnar epithelium began to return to the inner side, at this time the cervical erosion will disappear. Therefore, the cervical erosion is actually columnar epithelial ectropion. There is no need to worry too much. However, regular checkups of the cervix are necessary, not to prevent celiac disease, but to prevent cervical cancer. Regular cervical exfoliative cell tests for HPV and TCT are available, and as long as the results are negative, there is no need to worry too much.
