Dilation
Dilation refers to the opening of the cervix as your body prepares for and progresses through labor. It is measured in centimeters, starting at 0 (fully closed) and reaching 10 centimeters, which signals that your cervix is fully open and you are ready to push. Early labor typically brings dilation from 0 to 6 cm, while active labor takes you from 6 to 10 cm. Your midwife or obstetrician checks dilation through an internal examination. Progress can feel slow at first, but it often speeds up in active labor. Dilation alone does not determine when you will deliver, as effacement and the baby's position also matter.
What This Means for You
Understanding Dilation is an important part of your labor journey. When preparing for birth, understanding this term helps you discuss your birth preferences with your midwife or OB-GYN and know what to expect in the delivery room.

At KKH and NUH, dilation is checked periodically during labor admission to decide whether to admit you or send you home to wait. If your waters have broken, assessments may be spaced out to reduce infection risk.
