Experiencing one miscarriage is heartbreaking. Going through it more than once can feel incredibly isolating and deeply unfair. If you've had two or more failed pregnancies—what doctors call Recurrent Pregnancy Loss (RPL)—the first step toward finding hope is understanding why it might be happening.

The journey to uncover answers can feel just as daunting as the losses themselves, but it's a critical part of regaining a sense of control. Please know, you are not alone on this path.

The Heartbreak of Recurrent Miscarriage

While it might feel like it, this is not an uncommon struggle. Recurrent pregnancy loss affects about 1-3% of couples trying to conceive. The statistics can be stark: after one miscarriage, the risk of another is about 20%. After two, that risk can climb to around 29%.

For many couples, one of the most frustrating parts of this journey is that a significant number of cases are labeled "unexplained," meaning standard tests don't pinpoint a clear cause. This is where a deeper, more comprehensive look becomes so important.

The infographic below outlines some of the primary areas we investigate when looking for the root causes of recurrent loss.

As you can see, the potential reasons are complex and interconnected, ranging from genetics and uterine health to the intricate dance of your hormones. To give you a clearer overview, let's break these categories down.

Quick Guide to Potential Causes of Recurrent Miscarriage

This table provides a snapshot of the factors that are typically explored in a workup for recurrent pregnancy loss.

Looking at this list, it's easy to feel overwhelmed. Remember, the goal isn't to diagnose yourself but to understand the landscape of what's possible so you can have more informed conversations with your healthcare team.

The emotional impact of this journey is immense, and having a strong support system is crucial. If you know someone walking this path, learning some thoughtful ways to support a friend who miscarried can make a world of difference.

Let's Look at the 'Hardware': Genetics and Uterine Health

When we start digging into the reasons behind recurrent loss, one of the first places we look is the fundamental "hardware" of pregnancy—your genetics and your uterine structure.

A large number of early miscarriages happen because of random genetic issues in the embryo. You can think of it like a complex architectural blueprint that has a tiny but critical error, preventing the structure from ever being completed.

While most of these genetic hiccups are just bad luck, sometimes one of the parents carries something called a balanced translocation. This is where their own genetic material is rearranged. It doesn't impact their health one bit, but it can create genetic imbalances when passed on to an embryo.

For couples experiencing recurrent pregnancy loss, a balanced chromosomal rearrangement is found in one partner in about 4-5% of cases. That’s a huge jump from the 0.7% rate seen in the general population. The risk also climbs with each loss. You can explore the research on genetic factors from University of Utah Health Care to learn more.

Beyond the genetic blueprint, the physical space where the baby grows—the uterus itself—is just as crucial.

Your Uterine Environment

Even with a perfectly healthy embryo, structural issues in the uterus can prevent it from implanting or developing properly. Think of them as roadblocks on the path to a healthy pregnancy.

We see a few common culprits:

• A septate uterus: This is when a wall of tissue, called a septum, divides the uterus.
• Fibroids or polyps: These are common, non-cancerous growths that can get in the way or distort the uterine cavity.
• Uterine scarring: Often called Asherman's syndrome, this can be a result of previous surgeries or infections.

This reminds me of ‘Sarah,’ a 34-year-old marketing manager who came to us after her second early loss. Her doctor found a small fibroid, and she felt defeated, wondering if she'd ever carry a pregnancy. We created a personalized treatment plan for her that was simple to follow: weekly acupuncture to improve uterine blood flow and a few key herbal formulas. The goal was to build a supportive plan that helped her succeed, not overwhelm her. Working alongside her medical care, these steps helped optimize her uterine environment.

How Hormonal Imbalances Affect Pregnancy

I like to think of a healthy pregnancy as a well-orchestrated symphony. Hormones like your thyroid hormones, progesterone, and insulin all need to be in perfect harmony to create a safe and stable environment for a baby to grow. But if just one of these is out of tune, it can throw off the entire performance, sometimes leading to recurrent miscarriage.

We see this all the time in the clinic. Common issues include thyroid disorders, like an under-the-radar case of subclinical hypothyroidism or Hashimoto’s, which can disrupt the body's entire metabolic rhythm. Other times, things like uncontrolled insulin resistance or high prolactin levels can create an unstable environment during those critical first few weeks.

The Role of Progesterone and a Stable Lining

One of the most important hormones in this whole process is progesterone. Its main job is to build and maintain a thick, blood-rich uterine lining where the embryo can implant and get the nourishment it needs to thrive.

When progesterone levels are too low after ovulation, a condition we call Luteal Phase Defect, that lining can start to break down too soon. This makes it impossible for the pregnancy to be sustained. If you're worried this might be happening, you can learn more about what causes low progesterone in our detailed guide.

This reminds me of ‘Emily,’ a busy professional in her late 30s who came to us after struggling with irregular cycles and several early losses. Her functional tests revealed a previously undiagnosed thyroid issue. She was worried about adding more complexity to her life.

We created a personalized treatment plan that was simple and built to help her succeed. It included weekly acupuncture, a few key supplements to support thyroid function, and some straightforward dietary shifts. It was a manageable approach that didn't overwhelm her, and it worked to regulate her hormones naturally, paving the way for a successful, full-term pregnancy.

Investigating Autoimmune and Clotting Disorders

Sometimes, the reason for recurrent loss has nothing to do with hormones or anatomy. Instead, the body’s own defense system gets its wires crossed. In autoimmune conditions, the immune system can mistake a healthy, growing pregnancy for a threat and launch an attack, stopping it in its tracks.

It’s a classic case of mistaken identity. The most common culprit we see in the clinic is Antiphospholipid Syndrome (APS). With APS, the body makes antibodies that attack its own healthy cells, triggering inflammation and a higher risk of blood clots.

When Blood Flow Becomes the Problem

This brings us to a closely related problem: thrombophilias, or blood clotting disorders. These conditions can cause microscopic clots to form in the tiny, delicate blood vessels feeding the placenta. When that blood flow gets choked off, vital oxygen and nutrients can’t reach the developing embryo, which often leads to a loss.

This was the case for 'Megan,' a 37-year-old architect who came to us after three early losses. Her diagnosis of APS felt completely overwhelming. We developed a personalized treatment plan for her that was simple to follow: acupuncture sessions to calm her immune response and a focused anti-inflammatory diet. This plan was designed to seamlessly support the medical treatment she was receiving from her specialist. This integrated approach helped her feel more in control and ultimately led to a successful pregnancy.

While a diagnosis like this can sound scary, it's often very manageable with the right testing and a supportive, actionable plan.

The Impact of Lifestyle and Environmental Factors

While it's easy to get caught up in the complex world of genetics and hormonal testing, the foundation for a healthy pregnancy is often built on your daily habits and environment. This is good news, because these are the areas where you have the most control.

This becomes especially important as we age, a key factor when looking at what causes recurrent miscarriage. Age is one of the most significant predictors of pregnancy loss. After two losses, the risk of another miscarriage climbs from 24% for women aged 25-29 to 44% for those between 40-44. If you want to dive into the data, you can discover more about these findings.

Creating A Supportive Environment

Things like chronic stress, a nutrient-poor diet, and even exposure to environmental toxins can disrupt the delicate balance your body needs to sustain a pregnancy. We know that high levels of stress can weaken your immune system, which is why we often integrate practical, calming techniques like breathwork and mindfulness into our care plans.

Take ‘Jessica and Mark,’ a couple in their late 30s we worked with who were preparing for an embryo transfer. The process felt stressful and clinical. We put together a simple, personalized plan: couples acupuncture to lower stress, a few specific dietary changes to boost their nutrient intake, and targeted supplements to support both egg and sperm quality. It was an easy-to-follow approach that didn't just support their cycle—it made them both feel healthier, more connected, and empowered in their journey.

Tuning into these foundational areas is one of the most powerful ways you can support your body's potential. For more actionable steps, check out our guide on how to prepare your body for pregnancy.

Your Path Forward: Building a Plan That Works For You

Getting answers about what might be causing recurrent miscarriages is an important first step. But just as important—and maybe more so—is figuring out what to do next.

While your doctor is running the essential tests, we can work alongside them. Think of us as your partners, here to help build a plan that supports your body from every possible angle.

We pull from two powerful worlds: the time-tested wisdom of Traditional Chinese Medicine (like acupuncture and herbs) and the detailed, modern-day insights from Functional Medicine (which uses advanced testing and targeted nutrition). This combination lets us see the whole picture and create a clear path forward.

A patient I'll call ‘Anna’ came to us feeling completely lost after being told her losses were "unexplained." The last thing she needed was another complicated, stressful to-do list.

So we kept it simple. We started with weekly acupuncture to calm her nervous system and boost blood flow to her uterus, and we identified just a few key dietary changes. The goal wasn't just to prepare her body, but to help her feel hopeful and in control again. We build personalized treatment plans that are simple to follow and designed to help you succeed, not overwhelm you.

Your story is yours alone, and your plan to build your family should be too.

We're here to listen, to understand what you've been through, and to create a clear, manageable strategy designed just for you. When you're ready, take the next step by scheduling a consultation to talk about your journey and how we can help.

Your Questions, Answered

What Tests Should I Ask My Doctor For?

When we start digging into the reasons for recurrent miscarriage, the standard medical workup is a great place to start. Your doctor will likely recommend a few key tests to get a clear picture of what's going on.

This usually involves genetic screening (called karyotyping) for both you and your partner, and a look at the uterus itself with an imaging test like a hysteroscopy or HSG. They'll also run a full hormone panel to check your thyroid and progesterone levels, and screen for any underlying autoimmune or blood clotting issues that could be playing a role.

How Does Holistic Care Work with Conventional Treatment?

Think of it as a partnership. Our approach is designed to support and enhance the plan your medical doctor has put in place, not replace it. We’re filling in the gaps to give your body the best possible chance to succeed.

For example, we worked with a patient, ‘Maria,’ who was dealing with unexplained losses. While her doctor prescribed medication, we came alongside with acupuncture to calm her nervous system and improve blood flow to her uterus. We also used targeted nutrition to help balance her hormones naturally.

The goal wasn't to overwhelm her with a complicated regimen. We created a personalized treatment plan for her that was simple to follow, building a healthy, receptive environment for her pregnancy to thrive—which it did.

When Is the Right Time to Seek Help?

If you've experienced two or more miscarriages, now is the time to start asking for a deeper evaluation. You don't have to wait.

Investigating all the potential factors—from the medical side with a specialist to the foundational health side with a holistic provider—gives you the most complete picture of what's happening. More importantly, it gives you the clearest, most actionable path forward.
