The dangers of cervical adhesions include infertility, cyclic abdominal pain, and menstrual dribbling. Cervical adhesion usually has a history of abortion, diagnostic scraping and other intrauterine operations, which will affect the work and life to a certain extent, and should be promptly sought medical treatment. 1. Infertility: Cervical adhesion is the result of damage to the cervical canal leading to narrowing or atresia of the cervical canal, thus sperm entry into the uterus is blocked, leading to infertility. 2. Cyclic abdominal pain: after the cervical adhesion, the flow of menstrual blood will be hindered, and the blood will be easily stagnated or even refluxed into the fallopian tubes, pelvis, abdominal cavity and other parts of the uterus, resulting in cyclic abdominal pain. 3. Lack of menstrual flow: Cervical adhesion affects the smooth flow of menstrual blood, which is manifested as lack of menstrual flow but normal menstrual cycle. If the cervix is completely adhered, amenorrhea may occur. Patients with cervical adhesion are advised to seek medical advice in time to make a clear diagnosis before intervening in the treatment.
