There are several common causes of cervical hypertrophy: retention of mucus secreted by the cervical glands, and in severe cases, the formation of large and small cysts that make the cervix hypertrophic; long-term stimulation of inflammation, such as chronic pelvic inflammatory disease, which leads to cervical congestion and edema and hyperplasia of the cervical glands and interstitium, which leads to cervical hypertrophy; invasion of bacteria and viruses (mycoplasma and chlamydia), which leads to disturbance of the cervix; birth, miscarriage, and The cervical hypertrophy is caused by hyperplasia of the connective tissue of the uterus due to stasis left in the uterine cavity after the physiological period; fibrous hyperplasia within the myometrium due to chronic adnexitis; hypertrophy of the myometrium of the uterus under the stimulation of large amounts of estrogen when the ovaries are dysfunctional. Keep your hygiene clean in daily life, do proper exercise after delivery to avoid stasis of blood in the uterine cavity, and actively treat diseases that cause cervical hypertrophy.
