What tests should be done after two miscarriages?

Dr.
Dong: I would like to ask Dr.
Dong, I have experienced two instances of fetal demise, both of which required dilation and curettage.
In both cases, I had brown discharge early on, followed by a little bit of bleeding.
By the eighth or ninth week, the heartbeat had stopped.
It has been really painful for me.
It has been nearly three months since the procedure, and I would like to undergo some tests.
What are the most common causes of fetal demise? If it is related to immune system issues, can it be treated? I am very worried.
Thank you for your help!

More Info

I'm sorry to hear about your pregnancy losses. Experiencing two pregnancy losses, especially with the occurrence of missed miscarriages (also known as fetal demise), can be incredibly distressing and emotionally challenging. Understanding the potential causes and the appropriate tests to undergo can help you and your healthcare provider make informed decisions moving forward.

Causes of Pregnancy Loss
1. Chromosomal Abnormalities: The most common cause of early pregnancy loss is chromosomal abnormalities in the embryo. These abnormalities can occur randomly during fertilization or cell division. In many cases, the body recognizes these abnormalities and naturally terminates the pregnancy.

2. Uterine Abnormalities: Structural issues within the uterus, such as fibroids, polyps, or congenital anomalies, can interfere with implantation and fetal development. A thorough evaluation of the uterine anatomy through imaging studies like a hysterosalpingogram (HSG) or a saline infusion sonogram may be warranted.

3. Hormonal Imbalances: Hormonal issues, particularly related to progesterone, can affect the ability of the embryo to implant and grow. Low progesterone levels can lead to early pregnancy loss. Testing hormone levels, including progesterone, can provide insights into this aspect.

4. Immunological Factors: Some women may have immune system disorders that can lead to pregnancy loss. Conditions such as antiphospholipid syndrome (APS) can cause blood clotting issues, which may affect placental blood flow. Testing for specific antibodies can help identify these conditions.

5. Thyroid Disorders: Both hyperthyroidism and hypothyroidism can impact pregnancy outcomes. Thyroid function tests should be considered if there is a suspicion of thyroid dysfunction.

6. Lifestyle Factors: Factors such as smoking, excessive alcohol consumption, and obesity can also contribute to pregnancy loss. Addressing these lifestyle factors can improve overall reproductive health.

Recommended Tests
Given your history of two missed miscarriages, it would be prudent to discuss the following tests with your healthcare provider:
1. Karyotyping: This genetic test can be performed on both partners to identify any chromosomal abnormalities that may contribute to pregnancy loss.

2. Hormonal Assessments: Testing for progesterone levels, thyroid function (TSH, T3, T4), and other relevant hormones can help identify any hormonal imbalances.

3. Autoimmune Testing: Tests for antiphospholipid antibodies, lupus anticoagulant, and other autoimmune markers can help assess for immune-related issues.

4. Uterine Evaluation: A hysterosalpingogram (HSG) or a pelvic ultrasound can help visualize the uterine cavity and identify any structural abnormalities.

5. Blood Tests for Infections: Screening for infections that can affect pregnancy, such as cytomegalovirus (CMV) or toxoplasmosis, may also be beneficial.

Moving Forward
If any underlying issues are identified through these tests, your healthcare provider can discuss potential treatment options. For instance, if hormonal imbalances are found, hormone therapy may be recommended. If an autoimmune disorder is diagnosed, treatments may include anticoagulants or immunosuppressive therapies.

It's important to maintain open communication with your healthcare provider throughout this process. They can provide guidance tailored to your specific situation and help you navigate the emotional and physical aspects of trying to conceive again.

In the meantime, consider seeking support from counseling or support groups for individuals who have experienced pregnancy loss. Sharing your feelings and experiences with others who understand can be incredibly healing.

Remember, while the journey may be challenging, many women go on to have successful pregnancies after experiencing losses. With the right support and medical care, you can increase your chances of a healthy pregnancy in the future.
