Cervical hypertrophy can be caused by chronic inflammation, cervical gland cysts and other reasons. 1. Long-term stimulation of chronic inflammation: If the cervical area has long-term inflammatory infections, such as chlamydia, mycoplasma, etc., there will be chronic cervicitis, pelvic connective tissue inflammation and chronic adnexitis, which will cause repeated congestion and edema of the cervical tissues, cervical glands and interstitial hyperplasia, cervical hypertrophy. 2. Cervical adenocysts: cervical adenocysts are physiological changes in the cervix, mainly due to the replacement of columnar epithelium by squamous epithelium in the transformation zone of the cervix, blocking the mouth of the glandular ducts, obstructing the drainage of glandular secretions, so forming cysts, and the prolonged presence of cysts will also make the cervix hypertrophic. 3. Other reasons: multiple abortions or multiple births of women, will cause damage to the cervix, pathogens will enter the cervix, the organization of long-term inflammatory stimulation, will cause cervical hypertrophy. If there are no other symptoms of cervical hypertrophy, usually do not need special treatment, if the symptoms appear, it is recommended to go to the hospital in time.
