5 Surprising Causes of Miscarriage & How to Lower Your Risk | Dr. Soumya Shetty (2025)

One in Four Pregnancies Ends in Heartbreak – a staggering statistic that reveals the silent struggle many face on the path to parenthood. But what causes this devastating loss, and how can you protect your dream of a family? Doctors are now shedding light on surprising factors that contribute to miscarriage, offering hope and guidance for those navigating this painful journey.

The road to becoming a parent is often paved with excitement and anticipation, but for 26% of pregnancies, it’s a path abruptly cut short. Miscarriage, the loss of a pregnancy before 20 weeks, is far more common than most realize, yet it remains shrouded in silence and misunderstanding. And this is the part most people miss: it’s not always about what you’ve done wrong; often, it’s about factors beyond your control, from genetic quirks to hidden health conditions.

In a revealing interview with The Times of India, Dr. Soumya Shetty, a fertility specialist at Nova IVF Fertility, shared, “Miscarriage is a heart-wrenching experience for couples who’ve longed for a child. While many cases are due to natural, uncontrollable causes, understanding the reasons behind it can empower couples with early diagnosis, healing, and better planning for future pregnancies.”

But here’s where it gets controversial: while some causes are clear-cut, others challenge our understanding of fertility and health. Let’s dive into the five surprising factors doctors say you should watch for—and explore how modern science is offering new hope.

1. Chromosomal Abnormalities: Nature’s Silent Gatekeeper

A 2021 Lancet study revealed that nearly 50-60% of first-trimester miscarriages are caused by chromosomal errors in the embryo. These abnormalities prevent normal development, leading the body to naturally terminate the pregnancy. Dr. Shetty explains, “It’s nature’s way of ensuring only genetically healthy embryos continue.” Early genetic testing and counseling can help couples understand their risks—but is this enough? Should we be doing more to screen for these issues before conception?

2. Hormonal Imbalances: The Hidden Saboteurs

Conditions like polycystic ovary syndrome (PCOS) and thyroid dysfunction can disrupt the delicate hormonal balance needed for a healthy pregnancy. Low progesterone levels, crucial for maintaining the uterine lining, are also linked to early miscarriage. A 2020 Fertility & Sterility study found that addressing thyroid issues and insulin resistance can significantly improve pregnancy outcomes. But why aren’t more doctors screening for these conditions before pregnancy?

3. Uterine Abnormalities: The Unseen Barriers

Structural issues like a uterine septum, fibroids, or adhesions can restrict blood flow to the embryo, increasing miscarriage risk. Surgical correction, such as laparoscopic repair, has been shown to dramatically improve live birth rates. A 2022 Frontiers in Medicine meta-analysis reported a 72% live birth rate after such procedures. Yet, many women remain unaware of these options—why is this critical information not more widely shared?

4. Lifestyle and Environmental Factors: The Choices That Matter

Your daily habits play a bigger role than you might think. Smoking, excessive caffeine, obesity, and alcohol consumption are all linked to higher miscarriage risk. Chronic stress and exposure to pollutants can also disrupt hormonal balance and uterine health. Dr. Shetty emphasizes, “Good health begins long before conception. A balanced lifestyle, proper nutrition, and stress management are key to a healthy pregnancy.” But how much control do we really have over these factors in today’s fast-paced world?

5. Maternal Age: The Ticking Clock

After 35, the quality and quantity of eggs decline, increasing the likelihood of chromosomal abnormalities. However, advancements like IVF with preimplantation genetic testing (PGT-A) now allow doctors to identify healthy embryos, giving older women a better chance at success. But is society doing enough to support women who choose to start families later in life?

Beyond Biology: The Emotional Toll

Miscarriage isn’t just a physical loss—it’s an emotional earthquake. Studies show that nearly one in three women experience post-traumatic stress symptoms afterward. Grief, self-blame, and silence often compound the pain. Dr. Shetty stresses, “Emotional care must be an integral part of fertility treatment. Grieving, talking, and seeking professional support are essential for healing.” Fertility clinics are now incorporating counseling, nutrition, and mindfulness therapy into treatment plans, offering a holistic approach to recovery. But why does society still treat miscarriage as a taboo topic?

Building a Healthier Foundation

Preconception health can make all the difference. Simple steps like prioritizing rest, adopting a nutrient-rich diet, limiting caffeine and alcohol, maintaining a healthy weight, and engaging in light exercise can significantly improve fertility outcomes. A 2020 Human Reproduction Update study found that mindfulness-based stress reduction improves mental health for women struggling with infertility. But are these steps enough, or do we need systemic changes to support women’s reproductive health?

The Takeaway: Hope After Heartbreak

Miscarriage may feel like the end of the road, but for most women, it’s just a painful detour. With modern fertility science, compassionate care, and lifestyle adjustments, the majority go on to have healthy pregnancies. Dr. Shetty reassures, “While miscarriages are emotionally painful, most women who experience one or even multiple losses can eventually have a healthy baby with proper support.”

But here’s the question we must ask: Are we doing enough to support women and couples through this journey? Share your thoughts in the comments—let’s start a conversation that breaks the silence and fosters understanding. Remember, fertility isn’t just about conceiving life; it’s about nurturing resilience, trusting your body, and allowing hope to take root—softly, bravely, and beautifully.
