It is less likely that a woman with a loose opening during pregnancy will recover on her own. It usually needs to be improved by surgical cervical cerclage or usually by bed rest. This is because the loose opening of the cervix is mainly due to the fact that as the uterus increases in size during pregnancy, there is significant pressure on the opening of the cervix. If the cervical sphincter is not tense enough, the cervical opening may become loose. Because the uterus continues to increase in size during pregnancy, the pressure on the cervical os will only increase during pregnancy. If left untreated, it is likely to cause severe dilatation of the cervical opening, resulting in preterm labor. Therefore, women who have a loose cervical opening need to seek medical attention in a timely manner, which can be effectively improved by surgical cervical cerclage. Non-pregnant women can usually recover on their own, but they also need proper recovery training and medication.
