It is possible to have intercourse with third degree celiac disease. Celiac disease is now medically considered not a disease and not really a celiac disease, it is the columnar epithelium of the cervical canal that has migrated out to the cervix. When the doctor examines it, he or she will see that the celiac disease is actually columnar epithelium, and columnar epithelium is celiac-like to the naked eye, so it is possible to have intercourse. Since there are small blood vessels on top of the cervical erosion, sometimes it can cause bleeding after intercourse. If you have symptoms of erosion, you need to treat it with medication, but if not, don’t have concerns.
