What is the cause of a short cervix?

A short cervical canal is actually more of a problem of congenital development, but it can also affect fertility. If the cervix is ​​short, women are more likely to have premature birth or miscarriage during pregnancy, which can cause greater harm.

1. As for the length of the cervical canal, it is the result of its own development, that is, it is born like this and there is no reason.

2. Expectant mothers with short cervix are more prone to premature birth. A study of 2,900 pregnant women found that those whose cervix shortened within 24 weeks of pregnancy had a higher chance of premature birth than other pregnant women. Ultrasound was used to measure the pregnant woman's cervix and the uterine muscle ring that protruded into the vagina. It was found that the shorter the pregnant woman's cervix, the higher the premature birth rate. Data shows that pregnant women with a cervix of only 13 mm at 24 weeks of pregnancy are 14 times more likely to have a premature birth than those with a cervix of 40 mm or more.

3. Researchers explained that a short cervix can indicate a problem with the pregnant woman's birth canal. This, combined with abnormal uterine activity, can lead to premature birth. Therefore, experts believe that using ultrasound to measure the length of the cervix can help doctors predict which pregnant women have signs of premature birth and can then provide appropriate medical care. Gynecologists also said that another benefit of using ultrasound to examine pregnant women is that doctors can predict which women are suitable for "cerclage," which uses sutures to fix the position of the cervix to try to avoid premature birth.

4. Suggestion: If the cervical canal is too short, it is easy to dilate and cause premature birth. Therefore, you should stand less and walk less. Consult the doctor who examined you.
