The name “cervical erosion” has been removed from medical textbooks and replaced by “cervical columnar epithelial ectasia”, which is a normal physiological phenomenon in most cases. The symptoms of celiac disease can usually be detected during a gynecological examination, and patients are usually unable to determine this on their own. However, since it has been determined that cervical erosion is not a disease, there is no point in judging it. The so-called cervical erosion is a fine-grained red change in the appearance of the vaginal part of the cervix at the ectocervix and is not a true erosion caused by the pathological absence of epithelial ulceration, which is usually caused by the outward migration of the cervical columnar epithelium covering the squamous epithelium due to high estrogen. On the site of the cervix, there are two different types of cells, squamous epithelial cells near the vagina and columnar epithelial cells near the uterus, and the two types of cells behave differently in appearance. The area where the columnar epithelial cells and squamous epithelial cells meet is medically known as the “squamocolumnar junction zone”, which is susceptible to estrogenic effects. Before puberty, the ovarian function is not perfect and estrogen is low, so the columnar epithelium is more on the inner side. After menstruation, the columnar epithelium is influenced by estrogen and develops more towards the outside, so more columnar epithelium like “erosion” is found at the cervical opening during examination. After menopause, the estrogen level of women decreases and the columnar epithelium starts to return to the inner side, at which point the “vesicles” are invisible. Since cervical erosion is not a disease, there is no need to divide it into degrees, let alone to carry out any treatment. And many of the current treatments for celiac disease are wrong and are not recommended for blind selection.
