Cervical Insufficiency: Risks and Precautions for Future Pregnancies

The cervix is relatively lax?

Dear Dr.
Lu,
I am planning to get pregnant.
Two years ago, I was pregnant with twins through natural conception, but unfortunately, I had a preterm birth at five months, and neither baby survived.
Recently, I underwent a pelvic examination, and the doctor informed me that my cervix is slightly lax.
I am concerned about how this condition might affect any future pregnancies and what symptoms I should be aware of.
What preventive measures can I take? Are there any additional tests I should consider before trying to conceive again? Thank you!

Hello! Your physician suspects that you may have cervical incompetence.
If confirmed, this diagnosis is referred to as "cervical insufficiency." It is generally recommended to perform a cervical cerclage procedure around 4 months into the pregnancy to help prevent the cervix from dilating prematurely.
If there is indeed a problem and it is not addressed, the risk of miscarriage (preterm birth) in the next pregnancy is significantly high.
The methods to confirm the diagnosis include: 1.
Reviewing the medical history, where the previous preterm birth was typically characterized by "painless" cervical dilation (as opposed to painful contractions usually associated with preterm labor).
2.
After 3 to 4 months of the current pregnancy, closely monitoring weekly with ultrasound to observe any changes in the cervix, and taking action immediately upon noticing any signs.
Best wishes for your health from Dr.
Li-Cheng Lu, Director of Obstetrics and Gynecology at Taoyuan Hospital, Department of Health, Executive Yuan.

More Info

Cervical insufficiency, also known as cervical incompetence, is a condition where the cervix is unable to support a pregnancy, leading to premature birth or miscarriage. Given your history of a previous pregnancy loss at five months, it is understandable that you are concerned about the implications of a "slightly loose" cervix for future pregnancies.

The risks associated with cervical insufficiency primarily revolve around the inability of the cervix to remain closed during pregnancy, which can lead to early dilation and effacement. This condition can result in preterm labor, miscarriage, or premature rupture of membranes. The symptoms may not always be apparent until significant cervical changes occur, which is why monitoring and preventive measures are crucial.

To address your concerns, here are some key points regarding cervical insufficiency and recommendations for future pregnancies:
1. Diagnosis and Monitoring:
- The diagnosis of cervical insufficiency is often made based on a combination of medical history, physical examinations, and ultrasound assessments. If you have a history of painless cervical dilation or previous preterm births, these factors can contribute to the diagnosis.

- During your next pregnancy, it is essential to have regular ultrasounds starting around 16-20 weeks to monitor the length of your cervix. A shortening cervix can be an early indicator of potential issues.

2. Preventive Measures:
- If cervical insufficiency is confirmed, a common preventive measure is a cervical cerclage, which is a surgical procedure where a stitch is placed around the cervix to help keep it closed. This is typically performed around 12-14 weeks of gestation and may be removed later in the pregnancy.

- Bed rest or reduced physical activity may also be recommended, especially if there are signs of cervical changes or if you experience any contractions or bleeding.

3. Pre-Pregnancy Preparations:
- Before attempting to conceive again, consider discussing your situation with a maternal-fetal medicine specialist. They can provide tailored advice based on your medical history and current health status.

- It may also be beneficial to undergo a thorough evaluation, including a pelvic exam and possibly imaging studies, to assess the condition of your cervix and any other factors that may affect your pregnancy.

4. Emotional Support:
- Given your previous experience with pregnancy loss, it is important to address any emotional or psychological concerns you may have. Seeking support from a counselor or joining a support group for individuals who have experienced similar losses can be beneficial.

5. Lifestyle Considerations:
- Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding smoking or excessive alcohol consumption, can contribute to a healthier pregnancy. Additionally, managing stress through relaxation techniques or mindfulness practices can be helpful.

In conclusion, while cervical insufficiency poses risks for future pregnancies, proactive monitoring and preventive measures can significantly improve outcomes. It is essential to work closely with your healthcare provider to develop a comprehensive plan tailored to your specific needs. By taking these steps, you can enhance your chances of a successful and healthy pregnancy in the future.
