Recurrent Early Pregnancy Loss

Cervical insufficiency, a condition where the cervix weakens and dilates prematurely during pregnancy, is a significant contributor to recurrent early pregnancy loss (REPL). This condition often results in the loss of a baby before the 20th week of gestation. Understanding the causes, symptoms, and treatment options for cervical insufficiency is crucial for women experiencing repeated miscarriages.

Understanding Cervical Insufficiency

Cervical insufficiency occurs when the cervix, the lower, narrow part of the uterus, begins to open or dilate before the fetus is ready to be born. This premature opening can lead to the loss of the pregnancy. While the exact causes of cervical insufficiency are not always clear, several factors may contribute to its development:

● Previous cervical trauma: Procedures like cone biopsies, LEEP (Loop Electrosurgical Excision Procedure), or dilation and curettage can weaken the cervix.

● History of preterm birth: Women who have given birth prematurely in the past may be more susceptible to cervical insufficiency in subsequent pregnancies.

● Multiple pregnancies: Carrying twins or more can put extra strain on the cervix.

● Congenital cervical abnormalities: Some women are born with a structurally weak cervix.

● Short cervix: A cervix that is shorter than normal at the beginning of pregnancy may be at a higher risk of dilating prematurely.

● Hormonal imbalances: Hormonal changes during pregnancy can affect cervical tissue strength.

● Infection: Infections of the cervix or reproductive tract can contribute to cervical insufficiency.

Recurrent Early Pregnancy Loss (REPL)

REPL is a distressing condition characterized by multiple pregnancy losses within a short period. Cervical insufficiency is one of the leading causes of REPL, particularly when the losses occur in the second trimester. In many cases, women with REPL may experience pregnancy loss with decreasing gestational age for each pregnancy, indicating a progressive weakening of the cervix.

Symptoms of Cervical Insufficiency

Cervical insufficiency often doesn't present with noticeable symptoms until the cervix begins to dilate or shorten. However, some women may experience:

● Pelvic pressure or discomfort

● Lower back pain

● Vaginal bleeding or discharge

Diagnosis of Cervical Insufficiency

A healthcare provider can diagnose cervical insufficiency through a physical examination and additional tests, such as:

● Transvaginal ultrasound: This imaging technique can measure the length of the cervix.

● Cervical length assessment: A healthcare provider may use a speculum to measure the cervix during a pelvic exam.

Treatment for Cervical Insufficiency

The primary treatment for cervical insufficiency is cervical cerclage, a procedure that involves stitching the cervix closed to prevent it from dilating prematurely. It is usually done between 14 – 16 weeks of gestation. There are two types of cerclage:

● Emergency cerclage: This is performed after the cervix has already started to dilate.

● Prophylactic cerclage: This is done to prevent the cervix from dilating before it starts to shorten.

In some cases, bed rest or hormonal therapy may be recommended as supportive measures.

The Importance of Early Diagnosis and Treatment

If you are experiencing recurrent early pregnancy loss, it is essential to seek professional medical advice. Early diagnosis and appropriate treatment can help you achieve a healthy pregnancy.
