Length of cervical canal in pregnant women

Cervical canal length is one of the most important indicators of pregnancy monitoring.

During pregnancy, cervical canal length has a certain normal range. Generally speaking, cervical canal length is relatively long in early pregnancy, which gradually changes as pregnancy progresses, but usually fluctuates within a certain range. If cervical canal length is obviously abnormal, it may indicate that there is some potential problem.

Shorter cervical length is associated with an increased risk of preterm birth. Significant cervical shortening, especially near or below threshold values, requires serious attention and may require further evaluation and preventive measures to reduce the risk of preterm birth.

Pregnant women can monitor cervical length regularly by ultrasound so that abnormal changes can be detected in time. It helps doctors to make early diagnosis and intervention decisions to protect the health of pregnant women and fetuses.

However, it should be noted that there may be certain individual differences in the length of each pregnant woman's cervical canal. Some pregnant women may be born with a short or long cervical canal, but this does not necessarily mean that problems will occur. The key is to combine specific circumstances for comprehensive analysis and judgment.
