Commonly asked questions

What is the difference between a maternal-fetal medicine physician and an OB-GYN?

A maternal-fetal medicine (MFM) specialist receives a traditional obstetrics and gynecology (OB-GYN) education, but with an additional three years of training to learn how to treat medical complications related to pregnancy.

Why would I need a MFM physician?

High-risk pregnancies require extra care. OB-GYNs and MFMs work together to provide the best care possible for mom and baby.

Certain factors such as age (being over 35 or under 17) and health conditions (diabetes, high blood pressure, obesity, etc.) may cause a woman to have a high-risk pregnancy. Another factor is a mother with multiple babies.

Complications can be maternal or fetal. Some women have pre-existing conditions that require special follow up, while other women develop medical conditions because of pregnancy.

Patients may be referred to us by their physician for a variety of reasons, including:

  • Consultation
  • Detailed ultrasound
  • Genetic counseling
  • Genetic diagnostic procedure
  • Other testing
Can I see a MFM physician before I’m pregnant?

If you have pre-existing medical conditions, have had high-risk pregnancies in the past, or have a genetic disorder, you may benefit from a consultation with a MFM physician before trying to get pregnant. We can help address medical concerns or recommend lifestyle changes that can help you have a healthier pregnancy and reduce risks during pregnancy.

What can I expect at my first appointment?

The first appointment is a consultation appointment which includes an ultrasound assessment of your pregnancy. Your MFM physician will review any available medical records, surgical history, medications, or environmental exposures, and prenatal labs or screening tests. Your family history is also important to mention, if you have any concerns, to provide a complete picture of your health. 

Why would I be referred to an MFM for an ultrasound?

MFM physicians have specialized training in fetal ultrasound. An ultrasound is used to determine gestational age and assess for abnormalities with the fetus. The imaging requirements of an MFM ultrasound (level III) are highly meticulous and differ from that an ultrasound with your OB-GYN. This detailed scan may be necessary when there is a clinical concern that needs clarification. There is no pain or discomfort during the examination and no known harmful effects for the fetus or mother.

I’ve been referred to an MFM physician for care, does this mean my baby has a problem?

Most patients are routinely referred to an MFM physician for evaluation and reassurance. Many patients are in a high-risk category due to their age, health history, family history, or a medical condition. Just because a patient is referred to an MFM doesn’t mean there is an issue, most of the time patients leave feeling confident everything will be ok.

Sometimes your OB-GYN finds a concern and would like clarification. They refer you to an expert in maternal-fetal care for consultation and assistance. If we do find a concern, we are here to support you throughout your pregnancy.

What is genetic counseling?

Prenatal genetic counselors work with patients who have an increased chance of having a child with a birth defect or genetic condition.

Patients who are already pregnant or are considering having a child in the future can meet with our board-certified genetic counselor to learn more about the condition in question, understand their risks more clearly, and discuss options for prenatal screening and testing.
