Key Facts
Common Conditions Treated
Maternal-Fetal Medicine Specialists are trained to diagnose and treat a wide range of conditions. Here are some of the most common conditions that maternal-fetal medicine specialists help patients manage.
High-Risk Pregnancy Management
Comprehensive care for pregnancies complicated by maternal medical conditions, previous pregnancy complications, or other factors that increase risk to mother or baby.
Key Symptoms
Treatment Approach
MFM specialists develop individualized care plans, perform enhanced monitoring with specialized ultrasound and testing, coordinate with other specialists, and provide guidance on medication management and delivery planning.
Gestational Diabetes
Diabetes that develops during pregnancy, affecting blood sugar control and potentially causing complications for mother and baby including excessive fetal growth and birth complications.
Key Symptoms
Treatment Approach
MFM specialists manage blood sugar control through diet, medication, and insulin therapy when needed. They monitor fetal growth with serial ultrasounds, assess amniotic fluid levels, and plan appropriate timing and mode of delivery.
Preeclampsia and Hypertensive Disorders
Pregnancy-specific conditions involving high blood pressure that can affect multiple organ systems and pose serious risks to both mother and baby, including seizures and stroke.
Key Symptoms
Treatment Approach
MFM specialists monitor for disease progression with blood pressure tracking, laboratory testing, and fetal surveillance. They manage medications, determine optimal delivery timing, and coordinate intensive monitoring for severe cases.
Fetal Abnormalities and Birth Defects
Structural or genetic abnormalities in the developing fetus detected through prenatal screening, ultrasound, or diagnostic testing, requiring specialized evaluation and counseling.
Key Symptoms
Treatment Approach
MFM specialists perform detailed anatomic surveys and targeted ultrasounds, offer genetic counseling, perform diagnostic procedures like amniocentesis, coordinate with pediatric specialists, and develop comprehensive delivery and postnatal care plans.
Multiple Gestations (Twins, Triplets)
Pregnancies with two or more fetuses that carry increased risks of preterm birth, growth restriction, and other complications requiring specialized monitoring and management.
Key Symptoms
Treatment Approach
MFM specialists perform frequent ultrasound monitoring for fetal growth and well-being, screen for twin-specific complications, manage preterm labor prevention, and coordinate delivery planning at an appropriate facility.
Prenatal Diagnosis and Genetic Testing
Invasive and non-invasive testing to diagnose genetic conditions, chromosomal abnormalities, and other fetal conditions before birth.
Key Symptoms
Treatment Approach
MFM specialists perform amniocentesis, chorionic villus sampling (CVS), and fetal blood sampling. They interpret results, provide genetic counseling, and help families make informed decisions about pregnancy management.
Placental Abnormalities
Conditions affecting the placenta including placenta previa, placenta accreta spectrum, and placental abruption that can cause serious bleeding and delivery complications.
Key Symptoms
Treatment Approach
MFM specialists use advanced imaging including ultrasound and MRI to assess placental location and invasion. They coordinate surgical planning, arrange blood bank preparation, and ensure delivery at facilities equipped for potential complications.
Preterm Labor and Cervical Insufficiency
Conditions that increase the risk of delivering before 37 weeks of pregnancy, potentially leading to prematurity-related complications for the baby.
Key Symptoms
Treatment Approach
MFM specialists monitor cervical length, administer progesterone therapy when indicated, place cervical cerclage when appropriate, manage preterm labor with tocolytics, and administer steroids to promote fetal lung maturity.

- Heavy vaginal bleeding with or without abdominal pain - may indicate placental abruption or other serious complication
- Decreased or absent fetal movement - may indicate fetal distress requiring urgent evaluation
- Leaking fluid from the vagina before 37 weeks - may indicate preterm premature rupture of membranes
- Regular, painful contractions before 37 weeks - may indicate preterm labor requiring urgent intervention
- Fever over 101F with chills and abdominal tenderness - may indicate infection requiring immediate treatment
- Sudden severe swelling of face, hands, or legs - may indicate worsening preeclampsia

Maternal-Fetal Medicine Specialist vs. Other Specialists
Understanding the differences between medical specialists helps you choose the right provider for your needs.
Maternal-Fetal Medicine Specialist vs. Obstetrician-Gynecologist (OB/GYN)
An OB/GYN is a physician specializing in women's reproductive health and pregnancy care. An MFM specialist is an OB/GYN with 3 additional years of fellowship training in high-risk pregnancy. While OB/GYNs manage most pregnancies, MFM specialists focus specifically on complicated pregnancies involving maternal medical conditions, fetal abnormalities, and invasive prenatal procedures. Many patients see both during a high-risk pregnancy.
Maternal-Fetal Medicine Specialist vs. Reproductive Endocrinologist
A reproductive endocrinologist specializes in infertility and helping patients achieve pregnancy through treatments like IVF. An MFM specialist focuses on managing pregnancy once it is established, particularly high-risk pregnancies. Patients who conceived through fertility treatment are often referred to MFM specialists for pregnancy management, especially with multiple gestations or underlying medical conditions.
Maternal-Fetal Medicine Specialist vs. Neonatologist
A neonatologist is a pediatrician who specializes in caring for newborn infants, particularly those who are premature or critically ill. An MFM specialist cares for the mother and fetus during pregnancy. These specialists often work closely together when prenatal conditions are expected to require specialized newborn care, with the MFM managing care until delivery and the neonatologist taking over afterward.
Not sure which specialist you need?
Your primary care physician can help determine the right specialist for your condition and provide a referral if needed.

Frequently Asked Questions
Common questions about maternal-fetal medicine specialist
What is the difference between an MFM specialist and a regular OB/GYN?
An MFM specialist (perinatologist) is an OB/GYN with 3 additional years of fellowship training specifically in high-risk pregnancy. While OB/GYNs manage normal pregnancies and many complications, MFM specialists have advanced expertise in complex medical conditions, fetal abnormalities, and invasive prenatal procedures. Often, an MFM specialist will work in consultation with your regular OB/GYN rather than replacing them entirely.
Is amniocentesis safe, and will it harm my baby?
Amniocentesis is generally very safe when performed by an experienced specialist under ultrasound guidance. The risk of miscarriage from the procedure is approximately 1 in 500 to 1 in 1,000, which is lower than historical estimates. Most patients experience only mild cramping afterward. Your MFM specialist will discuss the specific benefits and risks based on your individual situation to help you make an informed decision.
Will I need to see an MFM specialist for my entire pregnancy?
This depends on your specific situation. Some patients need only one or two consultations for specific concerns, while others with complex conditions benefit from ongoing MFM care throughout pregnancy. Many MFM specialists work collaboratively with your primary OB/GYN, providing specialized input while your regular doctor continues routine prenatal care. Your MFM will discuss the recommended follow-up plan for your individual needs.
What happens if a fetal abnormality is detected?
If an abnormality is found, your MFM specialist will provide detailed counseling about the condition, its implications, and available options. This often includes additional testing to confirm the diagnosis, consultation with pediatric specialists who would care for your baby after birth, and discussion of all pregnancy management options. MFM specialists provide non-directive counseling to support your decision-making without pressure.
When is the best time to see an MFM specialist during pregnancy?
The optimal timing depends on your reason for consultation. Patients with chronic medical conditions benefit from preconception or early first-trimester consultations. First-trimester screening and CVS occur between 10-13 weeks. Detailed anatomy scans are typically performed around 18-22 weeks. Amniocentesis can be done after 15 weeks. For many complications, earlier referral allows more time for planning and intervention when possible.
