Understanding Pregnancy Loss: Common Causes and Myths
Dr. Marika Raff • July 21, 2025
Pregnancy loss, commonly referred to as miscarriage, is a deeply personal and often misunderstood experience. At Caperton Fertility Institute, with locations in Albuquerque, New Mexico, and El Paso, Texas, we believe that compassionate care begins with understanding. If you have experienced a loss or are navigating concerns about pregnancy, knowing the common causes and debunking persistent myths can provide comfort, clarity, and renewed hope.
What Are the Most Common Causes of Pregnancy Loss?
Miscarriage is more common than many people realize, affecting approximately 10% to 20% of known pregnancies. Most occur during the first trimester, and in many cases, they are beyond anyone's control. Here are some of the leading causes:
1. Chromosomal AbnormalitiesThe most frequent cause of early pregnancy loss is genetic abnormalities during fertilization. These anomalies prevent the embryo from developing normally and are typically not linked to anything the parents did or didn’t do.
2. Hormonal ImbalancesConditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or luteal phase defects can disrupt hormonal support essential for a healthy pregnancy.
3. Uterine or Cervical IssuesStructural concerns, including fibroids, polyps, or a septate uterus, can contribute to recurrent miscarriage or second-trimester losses.
4. Autoimmune DisordersConditions like lupus or antiphospholipid syndrome (APS) may cause the immune system to mistakenly target the developing embryo, leading to pregnancy loss.
5. InfectionsCertain infections, such as listeria, cytomegalovirus, and toxoplasmosis, may increase miscarriage risk if contracted during early pregnancy.
6. Lifestyle and Health FactorsSmoking, heavy alcohol use, and illicit drug use elevate the risk. Unmanaged chronic health conditions like diabetes or hypertension can also contribute.
Common Myths About Pregnancy Loss
Despite its frequency, miscarriage remains a topic filled with stigma and misinformation. Let’s dispel some of the most common myths:
Myth: Stress Causes MiscarriageEveryday stress is a part of life and is not linked to miscarriage. While chronic, extreme stress can affect overall health, it’s not a primary cause of pregnancy loss.
Myth: Exercise or Lifting Causes LossModerate physical activity is generally safe and often encouraged during pregnancy. Always follow your doctor’s guidance, but exercise alone is not a known cause of miscarriage.
Myth: Miscarriage Is Always PreventableMost miscarriages are caused by genetic or biological factors that cannot be controlled. It is not your fault.
Myth: It Only Happens OnceWhile many people experience only one loss, some have recurrent miscarriages, which may signal treatable underlying conditions.
Myth: You Must Wait Months to Try AgainPhysically, many individuals can begin trying again after one normal menstrual cycle, though emotional readiness is unique to each person. Always consult with your fertility specialist.
