What is the cause of the short neck?

The main reasons for short cervix are congenital abnormalities, multiple births or abortions, cervical lesions, and other factors. 1. Some women with congenital abnormalities may be affected by certain factors in the embryonic development process, resulting in short congenital development of the cervix. In this case, there may be a phenomenon that the length of the cervix is significantly shorter than the normal range from the beginning. 2. Multiple births or abortions Many births, especially multiparous women, or repeated abortion operations, may cause a certain degree of damage to the cervix, making the cervical tissue relatively weak and loose, and then the cervix may become shorter. During childbirth, the cervix needs to be fully dilated to deliver the fetus. Multiple such processes may affect the structure and length of the cervix; The operation of curettage in abortion surgery may also cause trauma to the cervix. 3. Cervical lesions Some cervical lesions, such as severe cervicitis, may lead to changes in cervical tissue under long-term inflammation stimulation, causing shortening of the cervix. The continuous effect of inflammation can make cervical tissue hyperplasia, fibrosis and other changes, affecting its normal shape and length. 4. Other factors Some endocrine diseases and connective tissue diseases may also be associated with a short cervix. For example, abnormal changes in hormone levels may affect the development and maintenance of the cervix; connective tissue diseases may affect the tissue structure and stability of the cervix.
