Celiac disease, also known as cervical columnar epithelial ectasia, is a physiologic phenomenon with no abnormal symptoms manifested in the body. When cervical columnar epithelial ectasia is secondary to cervicitis and pelvic inflammatory disease, symptoms such as abnormal leukorrhea, contact bleeding, lower abdominal pain or lower back pain may occur. Cervical columnar epithelial ectasia is a manifestation of the columnar epithelium moving out of the inner cervical canal to the outer cervical canal under the action of estrogen, which is a physiological phenomenon, and women will not have abnormal symptoms if there is no secondary disease. When the cervix is infected by inflammation or other stimuli, cervicitis may occur, and pelvic inflammatory disease may be triggered by upstream infection to the pelvis. Patients may have abnormal leukorrhea, such as increased leukorrhea secretion, thick or purulent secretion, and may have vulvar itching when stimulated by the secretion. It may also be accompanied by contact bleeding, lower abdominal pain or lower back pain. When cervical columnar epithelial ectasia occurs, accompanied by abnormal physical discomfort, it is recommended to consult a doctor in a timely manner, complete the relevant examinations, clarify the cause of the disease under the guidance of a professional doctor, and target treatment.
