Celiac bleeding in the same room is not necessarily serious. Celiac bleeding in the same room may be caused by chronic cervicitis, or it may be a highly squamous intraepithelial lesion of the cervix, or it may be early cervical cancer. If it is early cervical cancer, it is more serious. Cervical erosion alone is only a clinical sign and is not synonymous with disease. Whether celiac disease is present or not must be determined by relevant tests. Bleeding after sex can be seen in cervicitis, cervical polyps, highly squamous intraepithelial lesions of the cervix, or cervical cancer. Therefore, for cervical bleeding after intercourse, cervical cancer screening, i.e. cervical cytology and HPV testing, colposcopy and biopsy if necessary, must be performed to exclude high cervical squamous intraepithelial lesions and cervical cancer. If the cervical cytology and HPV test are normal, the high level of squamous intraepithelial lesions and cervical cancer have been ruled out, and the bleeding after intercourse with cervical erosion is considered to be caused by inflammation, which is not serious.
