A high-risk pregnancy is one in which the pregnant person or developing fetus faces an elevated likelihood of pregnancy complications that require specialized medical attention. For patients in New York, NY, understanding what makes a pregnancy high risk — and how to navigate that designation with confidence — is an important part of preparing for a healthy pregnancy. This guide covers the most common risk factors, existing health conditions that may affect pregnancy, warning signs to recognize, and how working closely with a maternal fetal medicine specialist supports better pregnancy outcomes for both the mother and baby. If you would like to discuss your individual situation with a specialist, contact Carnegie Hill Imaging For Women at (212) 722-7426.

What Makes a Pregnancy Considered High Risk

Not every pregnancy follows the same path. Healthcare providers use the term high risk to describe pregnancies where medical conditions, personal medical history, or lifestyle factors increase the likelihood of complications for the pregnant person, the developing fetus, or both.

Common reasons a pregnancy may be considered high risk include advanced maternal age (typically 35 or older), multiple gestation — meaning more than one fetus — previous preterm birth, recurrent miscarriages, and a history of pregnancy loss. Genetic conditions such as Down syndrome may also place a pregnancy in this category when identified through prenatal screening.

It is important to understand that a high-risk designation does not mean poor outcomes are inevitable. It means your healthcare team will monitor you more closely, schedule more frequent visits, and coordinate specialized prenatal care tailored to your needs.

Existing Health Conditions and Pregnancy High Risk Status

Many medical conditions that exist before pregnancy can affect fetal development and maternal health during gestation. Healthcare providers evaluate a patient’s full medical history before and during pregnancy to identify health problems that may require closer management.

Conditions commonly associated with a high-risk pregnancy include:

• High blood pressure: Chronic high blood pressure or gestational hypertension that develops during pregnancy can affect blood flow to the placenta and may contribute to preterm delivery or low birth weight.
• Gestational diabetes: When blood sugar control becomes difficult during pregnancy, it may increase the baby’s risk of complications. Developing diabetes during pregnancy also raises the risk of preterm labor.
• Thyroid disease: Both underactive and overactive thyroid conditions can affect fetal development and require careful management throughout pregnancy.
• Autoimmune and other chronic conditions: Conditions affecting the immune system, kidneys, or heart may elevate pregnancy risks and require coordinated care between specialists.

Patients with existing health conditions benefit from beginning specialized prenatal care early, ideally before conception when possible.

Lifestyle Factors That Affect Pregnancy Safety

Certain lifestyle factors can increase pregnancy risks and affect the health of the developing fetus. Healthcare providers discuss these factors with patients as part of a comprehensive prenatal care plan.

Patients who drink alcohol during pregnancy expose the fetus to substances that may interfere with normal fetal development. There is no established safe level of alcohol consumption during pregnancy, according to the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists. Similarly, the use of illegal drugs during pregnancy is associated with premature birth, low birth weight, and other complications that may require care in a neonatal intensive care unit after delivery.

Maintaining a healthy weight before and during pregnancy, taking folic acid as recommended by your healthcare team, and avoiding tobacco use all support healthier pregnancy outcomes. Your healthcare providers can help you establish practical steps that fit your specific health profile.

Warning Signs During a High-Risk Pregnancy

Recognizing potential warning signs early is an important part of managing a risk pregnancy safely. While routine prenatal care includes scheduled prenatal appointments to monitor both the mother and baby, patients should contact their healthcare team promptly if they experience:

• Vaginal bleeding at any stage of pregnancy
• Sudden or severe chest pain
• Signs of preterm labor, including regular contractions before 37 weeks
• Unusual changes in amniotic fluid or fetal movement
• Rapidly rising blood pressure readings

These symptoms may indicate potential complications that warrant immediate evaluation. Prompt communication with your healthcare providers is essential for protecting both the mother and baby’s health.

The Role of Maternal Fetal Medicine in High-Risk Prenatal Care

Maternal fetal medicine (MFM) is the subspecialty of obstetrics that focuses on managing complex medical conditions and pregnancy complications. A maternal fetal medicine specialist has advanced training beyond standard obstetric care, allowing them to evaluate and manage the full spectrum of high-risk conditions that may affect pregnant women.

Maternal fetal medicine care typically includes advanced diagnostic imaging, genetic counseling, amniocentesis, chorionic villous sampling, and detailed fetal anatomy assessments. These tools help the healthcare team identify genetic conditions, monitor fetal development, evaluate amniotic fluid levels, and develop a coordinated plan for managing health issues as they arise.

For pregnancies involving multiple gestation, previous preterm birth, birth defects, or complex medical conditions, a maternal fetal medicine specialist works alongside the patient’s primary obstetric provider to deliver coordinated, evidence-informed prenatal care throughout the pregnancy.

Frequently Asked Questions About High-Risk Pregnancy

Can a high-risk pregnancy result in a healthy delivery?

Many patients with a high-risk pregnancy go on to have healthy deliveries with appropriate prenatal care and monitoring. The goal of specialized care is to identify and manage potential complications early, supporting the best possible outcome for both the mother and baby. Individual pregnancy outcomes vary based on the specific conditions involved.

How early should I see a maternal fetal medicine specialist if I have health conditions?

Ideally, patients with existing health conditions or a history of pregnancy complications should consult a maternal fetal medicine specialist before conception or as early as possible in the first trimester. Early evaluation allows your healthcare team to establish a baseline, review your personal medical history, and develop a proactive prenatal care plan.

Will I need more prenatal visits than someone with a low-risk pregnancy?

Yes, a high-risk pregnancy typically requires more frequent prenatal visits and additional diagnostic assessments compared to routine prenatal care. The frequency of prenatal appointments will depend on your specific health conditions and how the pregnancy progresses. Your healthcare providers will establish a monitoring schedule tailored to your needs.

Does having a high-risk pregnancy affect future pregnancies?

In some cases, conditions or complications experienced during a current pregnancy — such as gestational diabetes, preterm delivery, or gestational hypertension — may be relevant for future pregnancies. Discussing your complete history with a maternal fetal medicine specialist before future pregnancies can help your healthcare team develop an appropriate plan from the outset.

Are support groups available for patients managing a high-risk pregnancy?

Support groups and peer communities can be a valuable resource for patients navigating the emotional and practical challenges of a high-risk pregnancy. Many hospital systems and maternal fetal medicine practices can provide referrals to support groups. Ask your healthcare team about options available through your care network.

What is the difference between premature labor and preterm birth?

Premature labor refers to the onset of regular uterine contractions that begin before 37 weeks of pregnancy. Preterm birth occurs when delivery happens before 37 weeks. Not all premature labor results in preterm birth — medical interventions may help delay delivery in some cases. Your healthcare providers will monitor closely and discuss management options if signs of premature labor develop.

Does maternal age alone make a pregnancy high risk?

Advanced maternal age — typically defined as 35 or older at the time of delivery — is one factor that may lead healthcare providers to classify a pregnancy as high risk. However, maternal age is evaluated alongside other health conditions, personal medical history, and pregnancy-specific findings. Many patients of advanced maternal age have healthy pregnancies with appropriate monitoring and prenatal care.
