Cervical erosion is the most common and predominant clinical manifestation of chronic cervicitis. It has a high incidence among women of childbearing age. Some patients do not have any symptoms, but because of the disease is terrified, or even think that it will be cancerous, and thus seek medical treatment, and even spend a lot of money on treatment. In fact, as long as there is a correct understanding of celiac disease, most patients do not need treatment. The following is an introduction to what celiac disease is and how to treat it correctly. The cervical epithelium is divided into two types: squamous epithelium and columnar epithelium. Squamous epithelium is located on the surface of the cervix and columnar epithelium is located in the cervical canal. The part of the cervix where the squamous epithelium meets the columnar epithelium is called the squamocolumnar junction, and this area is a favorable site for cervical cancer. The distribution of the two epithelia varies at different ages and during different menstrual cycles due to the influence of estrogen. The appearance of squamous epithelium is smooth under normal conditions, when the cervix is covered with squamous epithelium, that is, the cervix is smooth; after puberty, under the effect of estrogen, the cervix develops and enlarges, and the cervical canal mucous membrane tissues move outward, i.e., the columnar epithelium is moved outward, which gives the human naked eye the feeling of coeliac disease, which is not coeliac disease in the real sense, but pseudo-coeliac disease or the lining of the cervical canal moves outward. This kind of pseudo-celiac disease does not need treatment, when the estrogen level decreases (such as before and after menstruation), the columnar epithelium will naturally return to the cervical canal, and the cervix will become smooth. So what is true celiac disease? Because the surface of the cervix is often covered with more mucus or purulent secretions, these secretions for a long time to stimulate, impregnate the squamous epithelium around the external cervical opening, coupled with the inflammatory infiltration of the deeper tissues of the cervix, the squamous epithelium overlying the surface of the cervix loses its vitality and sloughs off, forming an ulcer, which is a true celiac disease. Pseudo erosion or endocervical ectasia is a physiological phenomenon, when the patient does not have symptoms such as increased secretion or contact bleeding, regular follow-up is usually sufficient and no treatment is required. Some people believe that endocervical ectasia is a precursor to cervical cancer, thus leading to unnecessary medications, especially physical therapy. In fact, endocervical ectopia does not increase the incidence of cervical cancer, but only makes it difficult to distinguish early cervical cancer from endocervical ectopia when observed with the naked eye. In less developed areas, early invasive cervical cancer is often mistaken as chronic cervicitis and physiotherapy is given, which leads to the spread of cancerous tissues through the bloodstream, and ultimately results in the spread of the tumor and the death of the patient. In order to avoid the two wrong tendencies of over-treatment and blind diagnosis and treatment mentioned above, it is indispensable to perform cervical smear examination regularly and before physical therapy of the cervix. If the columnar epithelium is infected, the mucous membrane of the cervicovaginal area is granular or papillary, with a large amount of milky-white mucous secretion or even yellowish purulent secretion, which in some cases may block the passage of sperm into the uterine cavity, leading to infertility. At this time, it is very necessary to take appropriate treatment measures. To summarize, celiac disease should be correctly distinguished from true celiac disease or pseudo celiac disease and treated differently. As long as the cervical smear (TCT/CCT/LCT) examination is normal and there is no symptom, it can be completely ignored and should not be trivialized.
