Recently, there are a lot of questions about celiac disease, and it is very troublesome to answer them, so the concept of “celiac disease” is briefly introduced to you here, so that the majority of women will no longer be troubled by “celiac disease”. The first thing is that “celiac disease” is a very common problem. First of all, “celiac disease” is not the name of the disease. It refers to the outgrowth of a single layer of columnar epithelium lining the mucosa of the cervical canal, where the squamous epithelium of the vaginal part of the cervix is partially or completely replaced by the columnar epithelium and the red cervical vascular stroma can be seen below it. Instead, we call it cervical columnar epithelial ectasia, which is not a pathological change, but one of the physiological changes of the cervix. The columnar epithelium of the cervical canal has low resistance and pathogens can easily invade and cause inflammation, so it is important to guard against cervical inflammation when cervical columnar epithelial ectopia occurs. However, there are many physiological conditions in which cervical columnar epithelial ectoplasia can occur, such as adolescence, pregnancy and women taking oral contraceptives, due to the increase of estrogen level in the body, the cervical columnar epithelium proliferates and the original squamous junction (migratory zone) moves out, so that the ectocervix is red and finely granular, resembling “cervical erosion”, which is a physiological change. The ectopic cervical columnar epithelium will return to the cervical canal when the estrogen level in the body decreases. As mentioned above, “cervical erosion” without clinical symptoms does not require any treatment, only cytological examination. If the cytology is abnormal, further treatment will be decided based on the cytology results. If there are symptoms, such as contact vaginal bleeding, even if the cytology is not abnormal, local physiotherapy can be used to destroy the ectopic columnar epithelium and cover it with new squamous epithelium to reduce the chance of infection and the chance of cervical inflammation.
