What are the causes of cervical relaxation during pregnancy?

During a woman's pregnancy, her body will undergo many changes, among which the biggest change is the uterus, which will gradually grow larger as the fetus grows. Under normal circumstances, the cervix is ​​closed to protect the fetus. However, many women will experience cervical relaxation during pregnancy. When this happens, it is easy for the fetus to fall out of the uterus.

Causes of cervical relaxation

1. Congenital cervical relaxation

Congenital cervical relaxation is a common clinical condition. In most cases, this situation occurs because the woman took certain medications during pregnancy or because of other reasons that caused the female uterus to be underdeveloped, thus causing the cervix to relax. Once this happens, women will experience miscarriage or premature birth every time they get pregnant. Therefore, for female friends, cervical relaxation must be treated as early as possible.

2. Acquired cervical relaxation

Acquired cervical relaxation is usually caused by too many curettages, frequent perineal examinations, or birth injuries. In addition, the cervical segment is also a common cause of acquired cervical relaxation. If a woman has acquired cervical relaxation, it will cause premature birth or miscarriage at an increasingly early stage. It is also possible that the pregnancy and delivery are normal at the beginning, but then premature birth or miscarriage will occur for some reason.

What to do if the cervix is ​​loose

1. Taking medication

If the cervix is ​​loose, you can take medicine to deal with it. The medicine will increase the tension of the uterine tube. Of course, this medicine will not affect the pregnancy and childbirth of the pregnant woman in the future. However, taking medication is not 100% effective.

2. Cerclage

If taking medicine doesn’t work, what should I do to relieve my cervical relaxation? You can choose surgery, which involves suturing the weak cervix to strengthen it. If a pregnant woman experiences bleeding, uterine contractions, or premature rupture of membranes, surgery cannot be performed. Many early miscarriages usually occur before fourteen weeks, so this operation should be performed after fourteen weeks. There is no unified answer as to the specific time for cerclage. The larger the fetus, the greater the chance of miscarriage and premature rupture of membranes caused by cerclage. Therefore, it is recommended that women in the second and third trimesters of pregnancy adopt conservative treatment methods such as rest. Cerclage is generally not recommended after 24 weeks of pregnancy. Before performing the cerclage, an ultrasound should be performed to confirm the survival of the fetus and the presence of any major malformations.
