A Guide to Your Choices
Disclaimer: This information is educational and should complement, not replace, discussions with your healthcare providers. Always consult with medical professionals about your specific situation and testing options.
Learning that your baby might have a health issue brings up many questions and emotions. If you’re wondering what a fetal anomaly means for you and your family, know that you’re not alone. These concerns affect about 1 in every 33 babies, according to the CDC.
This guide offers clear, compassionate information to help you understand these issues and confidently navigate your options.

What Are Birth Defects?
When healthcare providers discuss birth defects, they’re referring to structural or functional differences that develop while your baby grows in the womb. These issues, also called congenital anomalies, are present at birth and originate during fetal development.
These occur on a spectrum—from minor differences requiring little treatment, to more significant issues needing specialized care. The CDC reports that most congenital disabilities develop during the first three months, when organs form.
What Types of Conditions Might Occur?
Major Structural Issues
Significant changes affecting how the body looks or functions, often requiring medical intervention:
- Congenital heart defects (affecting nearly 1% of births, or about 40,000 babies each year, according to the CDC)
- Neural tube defects like spina bifida affecting the nervous system
- Cleft lip or palate involving facial development
- Limb formation differences
- Kidney abnormalities that can be life-threatening
Minor Variations
Smaller changes that typically don’t pose significant health problems:
- Extra fingers or toes
- Small skin tags
- Minor ear shape variations
Which Are the Most Common Conditions?
Understanding prevalent issues can help you know what to expect:
Chromosomal Issues
- Down syndrome (extra chromosome 21) – risk increases with maternal age
- Edwards syndrome and Patau syndrome
- Turner syndrome
Single Gene Disorders
- Cystic fibrosis
- Sickle cell disease
- Tay-Sachs disease
Heart Issues
Heart defects are the most common type of birth defect, with some causing abnormal heartbeat patterns that require immediate attention.
What Causes These Conditions?
According to the CDC, a complex mix of factors causes most congenital disabilities, including genes, behaviors, and environment. However, scientists do not fully understand how these factors might work together to cause these conditions.
This means these issues aren’t typically caused by anything you did or didn’t do.
Risk Factors That May Increase Your Chances
While most anomalies occur without clear cause, certain elements can affect the developing fetus:
Age-Related Elements
- The risk of having a baby with Down syndrome increases with age, especially if you are 35 years or older when you get pregnant
- However, the majority of babies with Down syndrome are stillborn to mothers less than 35 years old
Lifestyle and Environmental Elements
- Alcohol consumption can affect a baby’s health and development
- Smoking increases the risk for various issues
- Exposure to certain medications without medical guidance
- Environmental toxins or radiation exposure
Nutritional Elements
- Women who are pregnant or who could become pregnant should take 400 micrograms of folic acid every day to prevent neural tube defects
- Poor nutrition affects fetal development
- Vitamin deficiencies during critical development periods
Health-Related Elements
- Uncontrolled diabetes can affect organ development
- Maternal obesity increases certain risks, according to NICHD research
- Infections that can affect the fetus
How Are These Issues Detected?
Modern medical care offers several ways to assess your baby’s health throughout your pregnancy. Understanding these options helps you make informed decisions about testing.
Screening Tests
Screening tests help assess risk but don’t provide a definitive diagnosis. These tests determine if additional testing might be helpful.
First Trimester Options (10-14 Weeks)
- Blood test measuring specific pregnancy hormones and protein levels
- Ultrasound to measure neck thickness and assess early development
- Cell-free DNA testing—a blood test that screens for specific chromosomal conditions like Down syndrome, trisomy 18, and trisomy 13
Second Trimester Evaluation (15-22 Weeks)
The second trimester brings more comprehensive evaluation opportunities:
- Maternal serum screen is a blood test used to identify an increased risk for certain congenital disabilities. It is known as a “triple screen” or “quad screen,” depending on the number of proteins measured in the mother’s blood. AFP screening has about 65-80% sensitivity for detecting open spinal neural tube defects
- The second-trimester ultrasound is usually completed around 18–20 weeks of pregnancy
- Assessment of organ formation, including the heart, brain, kidneys, and limbs
- Evaluation of amniotic fluid levels
Important Limitations to Understand
- Cell-free DNA testing screens primarily for trisomy 21, 18, 13, and sex chromosome abnormalities
- It does not detect conditions screened for by ultrasound, such as neural tube defects, heart defects, and abdominal wall defects
- Additional screening may be needed for a comprehensive assessment
These screenings help detect many common congenital disabilities early in your pregnancy.
Diagnostic Tests Needed
When screening tests suggest increased risk or abnormal results, diagnostic tests provide clear answers about your baby’s health:
- Amniocentesis (15-20 Weeks): This procedure involves taking a small sample of amniotic fluid to analyze the baby’s chromosomes and genetic material. It can definitively diagnose many genetic disorders and chromosomal issues.
- Chorionic Villus Sampling (CVS) (10-13 Weeks): This earlier test examines placental tissue to detect genetic issues, allowing for earlier diagnosis.
- Advanced Imaging: Detailed imaging can identify many structural abnormalities and provide information about organ development and function. Specialized ultrasound can detect 97-100% of open neural tube defects when performed by experienced operators, though detection rates may vary in community settings.
Prenatal Diagnosis: How to Understand Your Results
When discussing test results, your doctor will help you understand what various findings mean for your baby’s health:
- Probability of specific issues
- Severity and potential treatment options
- Long-term outlook for the child
- Available interventions during pregnancy or after birth
What Happens After Receiving a Diagnosis?
Receiving news about a fetal anomaly naturally brings up questions about your pregnancy journey. Having accurate information helps you make informed decisions and plan appropriate care.
Several aspects affect how families navigate these choices, such as:
- Severity and long-term outlook for the child
- Available treatment options and their potential effects
- Potential for normal development and quality of life
- Support services available for families
Personal values:
- Religious or cultural considerations
- Family support systems
- Financial and practical considerations
- Previous experiences with similar situations
Treatment Options Available
Many issues can be successfully managed with appropriate medical care:
| Treatment Phase | Available Options |
| During Pregnancy | • Specialized monitoring throughout pregnancy • Medications to support fetal development • Fetal surgical interventions for certain conditions – these are highly specialized procedures available at only about 20 hospitals in North America and require extensive evaluation to determine candidacy<br>• Nutritional support and lifestyle modifications |
| Planning for Birth | • Delivery at specialized medical centers • Coordinated care teams ready at birth • Immediate treatment options available • Family support services |
| After Birth | • Early intervention services • Physical therapy and occupational therapy • Ongoing medical care and monitoring • Educational support and resources |
Second Trimester Termination: Understanding Your Options
For some families facing serious diagnoses, understanding all available options becomes important. With improved ultrasound technology, more conditions are being detected in the second trimester, and families may consider various paths forward.
Healthcare providers can discuss all available options, including continued pregnancy with specialized support or pregnancy termination, ensuring families have comprehensive information to make decisions that align with their values and circumstances.
Who Can Help You Navigate This Journey?
Your primary doctor or specialist will:
