Severe cervical erosion is one of the most serious types of celiac disease, with lesions occurring on more than 2/3 of the surface of the cervix. Patients with severe cervical erosion will have the following symptoms: first, abnormal leucorrhea, with yellowish color or purulent leucorrhea, accompanied by leucorrhea odor or leucorrhea with blood, which can be irritating and cause vulvar itching if there is more leucorrhea. Secondly, abdominal pain and discomfort during sexual intercourse as well as contact vaginal bleeding occurs because the texture of the erosion is very brittle and during sexual intercourse, the stimulation of sexual intercourse can easily lead to bleeding. During compound examination, if the relevant operation is performed, it can also lead to contact bleeding. For heavy cervical erosion, HPV infection needs to be excluded and cervical precancerous lesions need to be ruled out, and cancer prevention screening of the cervix needs to be perfected and active treatment carried out at the same time.
