Causes of cervical erosion

Cervical erosion is not an independent disease, but a manifestation of chronic cervicitis. It is called erosion, but in fact, it is not erosion, but a phenomenon in which the epidermis of the external cervical opening is replaced by another epithelial tissue after it falls off, which is very similar to real erosion, so it is named this way.

Cervical erosion is related to sex life. It is necessary to remind you that although cervical erosion is more common in married women, it does not mean that unmarried women do not have the possibility of cervical erosion. In addition to childbirth, abortion, infection, and surgical operations, which can cause cervical erosion, sex can also cause a certain degree of damage to the cervix, thus causing symptoms.

Some women pay great attention to hygiene, but lack the necessary knowledge, and often use a high concentration of cleaning solution to flush the vagina, which often has the opposite effect. This is because doing so will not only affect the growth of normal vaginal flora and reduce its ability to inhibit pathogenic bacteria, but can also cause varying degrees of damage to the cervical epithelium, eventually leading to erosion.

Symptoms: The main symptom is increased leucorrhea, which is often purulent. There may be pain in the lower abdomen and lumbosacral region and bladder irritation. Patients with more severe erosion may have varying degrees of pale bloody secretions. Typically, there is bloody secretion after sexual intercourse, and viscous purulent secretions from the cervix, which are not conducive to the passage of sperm and cause infertility.

Examination: Diagnosis is not difficult based on clinical manifestations, but it should be noted that cervical erosion is difficult to distinguish from cervical intraepithelial neoplasia or early cervical cancer in appearance. Routine cervical scraping and endocervical aspiration should be performed, and colposcopy and biopsy should be performed when necessary to confirm the diagnosis.

There is a clear boundary between the eroded surface of the cervix and the surrounding normal squamous epithelium. Clinically, it is often divided into three categories according to the area of ​​erosion: mild (Ⅰ°), moderate (Ⅱ°), and severe (Ⅲ°). If the erosion area accounts for 1/3 of the total area of ​​the cervix, it is mild cervical erosion. If the erosion area accounts for 1/2 of the total area of ​​the cervix, it is moderate cervical erosion. If the erosion area exceeds 1/2 of the total area of ​​the cervix, it is severe cervical erosion.
