Celiac disease, which is actually a manifestation of chronic cervicitis, is now renamed cervical columnar epithelial ectasia. The normal surface of the cervix is smooth and slightly white in color compared to flesh-colored. It is now believed that cervical erosion is still associated with sexual intercourse, especially frequent and unclean sexual intercourse. If there happens to be some pathogenic bacteria in the vagina or glans circumcision, the pathogenic bacteria can infect the damaged cervical surface epithelium, resulting in acute inflammation of the cervical surface epithelium, which over time becomes a fine granular red area. Cervical erosion can be divided into 3 degrees according to the size of the erosion area: 1. Mild erosion (degree I) means the erosion surface is less than 1/3 of the entire cervical area; 2. Moderate erosion (degree II) is 1/3-2/3; 3. Severe erosion (degree III) means the erosion surface is greater than 2/3 of the entire cervical area. So does cervical erosion affect pregnancy? If the cervical erosion is very mild, of course, it will not affect the pregnancy, only need to do TCT regularly every year, if there is no problem, then it will be fine; the infertile with severe erosion and recurrent vaginitis tend to be treated; the infertile with severe erosion, although they intend to get pregnant in the short term, can be suspended or treated symptomatically for vaginitis, and then treated after childbirth. Those who are infertile with severe erosion and recurrent vaginitis and do not intend to have children in the long term (for example, 2-3 years) should be given treatment.
