Definition: Incompetent cervix is a condition in which a woman’s cervix begins to open, or dilate, in the second trimester of pregnancy. The cervix is called “incompetent” because it isn’t able to stay closed long enough to allow a pregnancy to reach full term.
Many women are diagnosed with an incompetent cervix after they have suffered from one or more second trimester pregnancy losses, or after they deliver a very preterm baby. Other women are diagnosed with an incompetent cervix after a cervical ultrasound shows that their cervix is beginning to open early in pregnancy.
If an incompetent cervix is diagnosed in a pregnant woman, many physicians will place a cerclage, or a stitch in the cervix, to help it stay closed until the baby is fully developed.
Also Known As: Cervical insufficiency
