What Causes Recurrent Miscarriage?

Breaking the Silence

Miscarriage happens a lot, but it’s not something people talk about much. When it does happen, it can make you feel really sad, embarrassed, and like something is wrong with you. It’s tough to express how you feel because it seems like a taboo topic.

Because it’s such a private and emotional thing, many folks keep their feelings to themselves. They don’t even tell their closest friends and family about their pain.

Even though more people are starting to talk openly about miscarriage, and there are groups trying to make it less of a taboo, some folks still don’t know what to say or how to say it, so they keep quiet.

When you go through not just one miscarriage, but two or more, it can make you feel really lost and hopeless. You start to wonder if you’ll ever be able to have a family like you dreamed of.

So, let’s talk about what we know, what we don’t know, and how doctors and science can help folks who are struggling with losing pregnancies over and over again.


Experiencing a miscarriage can be devastating, but facing recurrent miscarriages can be especially challenging and leave you wondering why it keeps happening. Recurrent miscarriage, defined as the loss of three or more consecutive pregnancies before the 20th week, affects about 1% of couples trying to conceive. While it’s a heartbreaking experience, understanding the potential causes can help you navigate this difficult journey. Let’s explore some common reasons behind recurrent miscarriage:

1) Chromosomal Abnormalities

Chromosomal abnormalities, where the genetic material isn’t properly formed, are a leading cause of miscarriage, especially in early pregnancy. These abnormalities typically occur by chance and can prevent the embryo from developing normally, leading to miscarriage. While most miscarriages due to chromosomal issues are random events, recurrent miscarriages caused by chromosomal abnormalities can be a result of parental genetic factors.

2) Hormonal Imbalances

Hormonal imbalances, such as insufficient levels of progesterone (a hormone crucial for maintaining pregnancy) or thyroid disorders, can increase the risk of recurrent miscarriage. These imbalances can disrupt the delicate hormonal environment needed to support a pregnancy, making it difficult for the embryo to implant and thrive.

3) Uterine Abnormalities

Anomalies in the structure of the uterus, such as a septum (a band of tissue dividing the uterus), fibroids (noncancerous growths in the uterus), or scarring from previous surgeries, can interfere with implantation and increase the risk of miscarriage. These abnormalities may prevent the uterus from providing a suitable environment for the embryo to grow and develop.

4) Autoimmune Disorders

Certain autoimmune disorders, where the immune system mistakenly attacks the body’s tissues, can also contribute to recurrent miscarriage. Conditions such as antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) can cause blood clotting issues and inflammation in the uterus, increasing the likelihood of miscarriage.

5) Lifestyle Factors

Various lifestyle factors, including advanced maternal age, obesity, smoking, excessive alcohol consumption, and illicit drug use, can negatively impact fertility and increase the risk of recurrent miscarriage. Making healthy lifestyle choices, such as maintaining a balanced diet, exercising regularly, and avoiding harmful substances, can help reduce the risk of miscarriage.

Seeking Support and Guidance

Experiencing recurrent miscarriage can take a significant toll on your emotional well-being, and it’s essential to seek support from loved ones, healthcare professionals, or support groups who understand what you’re going through. Your doctor can conduct tests to identify any underlying causes of recurrent miscarriage and develop a personalized treatment plan to address them.


While recurrent miscarriage can be heartbreaking and challenging, it’s important to remember that you’re not alone, and there is hope for a successful pregnancy. With the right support, guidance, and medical interventions, many couples go on to have healthy pregnancies and babies after experiencing recurrent miscarriage. Don’t hesitate to reach out for help and explore your options on this journey toward parenthood.
