What are the causes of cervicitis?

Cervicitis is a common disease among married women, and there are many female friends suffering from cervicitis. So what are the causes of cervicitis? Regarding this issue, let our experts explain to you the causes of cervicitis.

What are the causes of cervicitis? The following is an introduction to the causes of cervicitis:

1. True erosion: Since the surface of the cervix is ​​often covered with a lot of mucus or purulent secretions, these secretions have long stimulated and soaked the squamous epithelium around the external os of the cervix. Coupled with the inflammatory infiltration of the deep tissues of the cervix, the squamous epithelium covering the surface of the cervix loses its vitality and falls off, forming ulcers. This is true erosion.

2. Congenital erosion: During fetal development, except for the vaginal epithelium, other reproductive tract epithelia originate from the body cavity epithelium. When the embryo develops to the 3rd or 4th month, the cylindrical epithelium in the cervical canal and the squamous epithelium on the surface of the cervical vagina can be clearly distinguished. At this time, the junction of the two types of epithelium is not at the cervical os, but is located inside the cervical canal. When the embryo develops to the 6th-7th month, the columnar epithelium of the cervix has acquired the secretory function. In the late pregnancy, these columnar epithelia are affected by maternal estrogen, and the columnar epithelium of the cervical mucosa proliferates and begins to grow outward from the cervical os and beyond the external os of the cervix. Therefore, about 1/3 of the cervix of newborn girls has an appearance similar to cervical erosion in adults.

3. Acquired erosion: Acquired erosion is in contrast to congenital erosion. It mostly occurs in women of childbearing age with vigorous ovarian function. The columnar epithelium of the cervical canal is overproliferated under the influence of estrogen produced by the ovaries, exceeding the external cervical os, causing the external cervical os to become eroded. The appearance of this type of erosion is no different from erosion caused by inflammation, but the cause of the erosion is different. This type of erosion is more common during pregnancy, and most of them can disappear on their own after delivery. Due to different causes, the clinical manifestations are somewhat different. Such patients will also have more leucorrhea, but the nature of the leucorrhea is clear and mucous, tightly attached to the surface of the cervix, and not easy to wipe off.

4. Pseudo-erosion: The pathological concept of erosion refers to "the shedding of the surface epithelium". The most common cervical erosion in clinical work is the red area around the external cervical opening. During colposcopy, after applying 3% acetic acid on the surface of the red area, it can be seen that the red area is partially changed into a "grape bunch", which is caused by columnar epithelial edema. If a biopsy is performed on the area, columnar epithelium can be seen on the surface under a microscope.

I believe that after reading the above explanation, you will have a certain understanding of the causes of cervicitis! I hope the above explanation can help you.
