Pregnancy is a major physiological journey, and most pregnancies progress without serious complications. However, some pregnancies require closer observation because certain maternal health conditions, previous pregnancy complications, fetal concerns, or pregnancy-related factors can increase the possibility of complications. These are commonly described as high-risk pregnancies.
Being told that you have a high-risk pregnancy does not necessarily mean that something will go wrong. It means that you and your baby may benefit from more specialized assessment, closer monitoring, and individualized care throughout pregnancy.
A Maternal-Fetal Medicine specialist can help assess potential risks, recommend appropriate investigations, monitor fetal development, and coordinate care when specialized management is required.
What Is a High-Risk Pregnancy?
A high-risk pregnancy is one in which the mother, baby, or both may have a higher-than-usual risk of developing health complications during pregnancy, childbirth, or the postpartum period.
A pregnancy may be considered high risk because of an existing medical condition, a previous pregnancy complication, multiple pregnancy, an abnormal screening result, or a concern identified during an ultrasound or other investigation.
Importantly, risk can change during pregnancy. A pregnancy that begins as low risk may require additional monitoring later if a new condition or fetal concern develops.
What Can Make a Pregnancy High Risk?
Several factors can contribute to a high-risk pregnancy. These may include:
Maternal Medical Conditions
Certain health conditions can require additional monitoring during pregnancy, including:
- High blood pressure and hypertensive disorders
- Diabetes or gestational diabetes
- Autoimmune disorders
- Other significant medical conditions
The appropriate monitoring depends on the mother’s health, the stage of pregnancy, and how the condition is affecting the pregnancy.
Previous Pregnancy Complications
A history of certain complications may influence care during a subsequent pregnancy. These can include:
- Previous stillbirth
- Previous preterm birth
- Recurrent pregnancy loss
- Previous pregnancy complications
- Certain complications affecting the mother or baby
A detailed review of previous pregnancy records can help determine whether additional assessment is appropriate.
Multiple Pregnancy
Twin and higher-order pregnancies may require specialized monitoring because the risks can differ depending on factors such as the number of babies and whether they share a placenta.
Monitoring may include assessment of chorionicity, serial fetal growth assessment, and surveillance for complications such as twin-to-twin transfusion syndrome (TTTS) in relevant pregnancies.
Fetal or Placental Concerns
A pregnancy may require specialist assessment when investigations suggest:
- Fetal growth restriction
- Structural abnormalities
- Abnormal amniotic fluid levels
- Placental abnormalities
- Other fetal or pregnancy-related concerns
In such situations, advanced fetal imaging and specialist counselling can help guide further care.
How Is a High-Risk Pregnancy Monitored?
Monitoring is individualized according to the specific risk factors and stage of pregnancy. Depending on the clinical situation, assessment may include:
Advanced Ultrasound
Ultrasound plays an important role in monitoring fetal development. Depending on the stage and indication, assessments may include:
- Early pregnancy and viability scans
- Nuchal translucency (NT) scan
- First-trimester structural assessment
- Genetic sonogram
- Level II or TIFFA scan
- Growth scans
- Fetal neurosonography
- Fetal echocardiography
- Placental and amniotic fluid assessment
Doppler Studies
Doppler ultrasound can be used when clinically indicated to assess blood flow and help evaluate fetal and placental circulation.
Fetal Well-Being Monitoring
Depending on the pregnancy, doctors may recommend investigations such as:
- Non-stress test (NST)
- Cardiotocography (CTG)
- Biophysical profile (BPP)
- Fetal growth surveillance
- Amniotic fluid assessment
The timing and frequency of these tests depend on the individual pregnancy and should be determined by the treating medical team.
When Should You Consult a Maternal-Fetal Medicine Specialist?
A referral to a Maternal-Fetal Medicine specialist may be appropriate when a pregnancy requires specialized assessment or monitoring.
You may be advised to seek specialist evaluation if you have:
- A previous stillbirth or significant pregnancy complication
- Recurrent pregnancy loss
- A history of preterm birth
- A twin or multiple pregnancy
- An abnormal ultrasound finding
- An abnormal prenatal screening result
- Suspected fetal growth restriction
- A suspected fetal structural abnormality
- Certain maternal medical conditions
- A pregnancy requiring specialized fetal monitoring
A specialist consultation can also be useful when you want a second opinion about an ultrasound finding, screening result, or pregnancy management plan.
What Is the Role of Maternal-Fetal Medicine?
Maternal-Fetal Medicine focuses on the care of pregnancies that require specialized assessment because of maternal, fetal, or pregnancy-related concerns.
A Maternal-Fetal Medicine specialist may be involved in:
- High-risk pregnancy assessment
- Advanced fetal ultrasound
- Prenatal diagnosis
- Fetal anomaly evaluation
- Multiple pregnancy surveillance
- Prenatal genetic counselling
- Fetal echocardiography
- Fetal neurosonography
- Invasive prenatal diagnostic procedures when indicated
- Pregnancy and delivery planning
- Coordination with other specialists
For some pregnancies, care may involve collaboration between obstetricians, neonatologists, pediatric cardiologists, pediatric surgeons, genetic specialists, anaesthetists, and other healthcare professionals.
Can a High-Risk Pregnancy Have a Healthy Outcome?
Yes. Being classified as high risk does not automatically mean that a pregnancy will have a poor outcome.
The outcome depends on the reason for the increased risk, the mother’s health, fetal condition, gestational age, response to monitoring, and timely management of complications.
Regular antenatal care and appropriate specialist assessment can help identify potential concerns early and allow the healthcare team to develop an individualized care plan.
Final Takeaway
A high-risk pregnancy requires careful attention, but it should not automatically be a source of fear. Early identification of risk factors, appropriate investigations, regular monitoring, and timely specialist care can help support the health of both mother and baby.
If your pregnancy involves previous complications, multiple pregnancy, an abnormal ultrasound or screening result, fetal concerns, or certain maternal health conditions, discuss your individual situation with your obstetrician or a Maternal-Fetal Medicine specialist.

Frequently Asked Questions
Is every high-risk pregnancy dangerous?
No. High-risk means that certain factors may increase the possibility of complications and that additional monitoring or specialist care may be appropriate. Many high-risk pregnancies progress well with appropriate care.
When should I see a Maternal-Fetal Medicine specialist?
You may be referred when there are maternal health concerns, previous pregnancy complications, multiple pregnancy, abnormal screening results, ultrasound findings, fetal growth concerns, or suspected fetal abnormalities.
Does a high-risk pregnancy always require more ultrasounds?
Not necessarily. The frequency of ultrasound examinations depends on the specific medical indication and should be determined by the treating healthcare team.
Is a twin pregnancy considered high risk?
Twin pregnancies may require closer monitoring because certain complications occur more frequently than in singleton pregnancies. The level of monitoring also depends on the type of twin pregnancy and other individual factors.
What happens if an ultrasound shows a fetal abnormality?
An abnormal or uncertain ultrasound finding may require further specialist assessment, advanced imaging, counselling, or additional diagnostic testing depending on the finding.
