Published | 6 min read
An incompetent cervix is a heartbreaking condition that leads to miscarriages. However, many women don't know they have it until they've had several miscarriages.

However, the condition is difficult to diagnose. Therefore, a woman may experience several miscarriages before she finds out why. After you are diagnosed, it can be very easy to manage.
Read on to learn what an incompetent cervix is and why it may lead to miscarriage. Our experts also provide tips for supporting your womb health so you can carry a healthy baby full-term.
What Is An Incompetent Cervix?
Cervical incompetence or cervical insufficiency occurs when the cervix opens before a woman goes into labor. This leads to a miscarriage or preterm birth.
As the condition is difficult to diagnose, women with an incompetent cervix often have to go through the trauma of repeated miscarriages or preterm birth before it is suspected. However, once diagnosed, the condition can be effectively managed.
A woman’s cervix is closed and firm before pregnancy. As pregnancy progresses, the cervix softens, decreases in length, and opens in preparation for labor and delivery.
An incompetent cervix undergoes these changes and opens too soon, sometimes even in the second trimester, causing a miscarriage. If the cervix opens later in the pregnancy, it may result in preterm birth.
Do You Have An Incompetent Cervix?
You may not realize that you have an incompetent cervix, and many women don’t have any known risk factors. You might be at a higher risk of cervical incompetence if you had a surgical procedure on your cervix.
Certain congenital conditions that result in uterine abnormalities or connective tissue disorders also predispose you to an incompetent cervix, especially during early pregnancy.
There may be no signs and symptoms of the condition. Some women have mild pelvic pain or spotting between the 14 and 20 weeks of pregnancy. Backache, mild abdominal cramps, a sensation of pelvic pressure, light vaginal bleeding, and a change in the vaginal discharge may also be noted.
Though these symptoms might be common in any pregnancy, do let your doctor know if you’ve suffered from a past pregnancy loss or a surgical procedure on your cervix. A history of painless labor and preterm deliveries may also hint at the condition.
Your obstetrician may ask you to undergo a few tests to check for an incompetent cervix and rule out any infections. A transvaginal ultrasound can determine the length of your cervix and check if the membranes are protruding. This type of ultrasound uses a slender probe placed inside the vagina to visualize.
What Does TCM Say About An Incompetent Cervix?
According to Traditional Chinese Medicine (TCM), several lifestyle factors contribute to this imbalance. These are work stress, work-life imbalance, insufficient and low-quality rest and sleep, lack of emotional management, an unhealthy diet, poor eating habits, and binge-drinking, and smoking.
“These habits disrupt qi (vital life force) and blood circulation, causing the formation and accumulation of pathogens like Cold, Heat, Dampness, phlegm, Stagnated
Over time, deficiencies of vital fundamental substances like qi, blood, yin (cooling energy and body fluids), and yang (warming energy) can arise. This causes a weakening of the Penetrating and Conception vessels and vital organs like the Liver, Spleen, and Kidneys, further worsening the cervix’s functional state.
Tips For Managing An Incompetent Cervix
If you have been diagnosed with an incompetent cervix, be assured that several treatments can manage the condition. You can’t prevent an incompetent cervix, but you can take care to ensure it doesn’t cause problems during your pregnancy.
Here are some ways to manage the condition:
Practice good prenatal care
Be regular with your prenatal visits to the doctor and voice your concerns, no matter how minor they may seem to you. Eat a healthy and balanced diet and ensure you take all your
You can also add several Chinese herbs to your diet to support a healthy pregnancy. Bird’s nest can help relieve Heat in the body. Meanwhile, Codonopsis and red dates tea can improve vitality and Stagnated Qi.
During early pregnancy, try to reduce the ‘cooling effects’ of vegetables by grilling them because many vegetables are cooling in nature. Incorporate more warming herbs into your diet, such as ginger. Avoid foods or beverages that are yin (cold) in nature, such as lettuce, sashimi, white cabbage, and drinks prepared using barley grains and tea leaves.
If you have a history of early premature births or are suspected of having an incompetent cervix, your doctor will monitor your cervix with repeated transvaginal ultrasounds.
If you have been diagnosed with an incompetent cervix, the condition will likely recur in subsequent pregnancies so it’s best to keep your doctor informed.
Consider progesterone injections during pregnancy
If you have a history of premature births, your doctor might suggest supplementations with progesterone hormone after the first trimester. This is available as weekly injections.
Close the cervix with a cervical stitch
If your doctor may also recommend a surgical procedure known as the cervical cerclage to prevent premature birth. In this procedure, the cervix is closed with strong stitches that are removed only toward the end of pregnancy. This is a safe procedure that has been in use for decades and significantly reduces the chances of preterm birth.
Strengthen your body to support the pregnancy
Physician Yew advises that in TCM, pregnant women with recurring miscarriages should strengthen their bodies and address any imbalance in the body’s constitution.
He cautions against self-medicating with herbal medicines. “TCM can lower the risk of repeated miscarriages through herbal medication,
