What Is an MFM Specialist?

A maternal-fetal medicine specialist is a doctor who helps take care of women having complicated or high-risk pregnancies. Being pregnant with twins is considered a high-risk pregnancy, so it's likely that an MFM specialist will be part of your medical team. These doctors are obstetricians who also completed 3 extra years of training in high-risk pregnancy. They are also called perinatologists or high-risk pregnancy doctors.

What an MFM Doctor Does

An MFM doctor:

  • Gives regular prenatal care for women with high-risk pregnancies
  • Helps manage the mother's existing health problems, such as diabetes and high blood pressure
  • Cares for women who develop complications during pregnancy or childbirth
  • Does tests and procedures, such as ultrasound, to check your babies' growth and development
  • Checks for birth defects and genetic disorders with tests such as amniocentesis, chorionic villus sampling (CVS), or umbilical cord sampling
  • Diagnoses and manages birth defects, heart problems, and blood disorders in a developing baby, including performing surgery if needed
  • Monitors labor and handles the delivery
  • Manages any of the mom's health problems after pregnancy, such as excessive bleeding, infections, or high blood pressure
  • Identifies risks and provides recommendations for future pregnancies



Why Else You Might Need an MFM Doctor

If one is available near you, you'll likely see an MFM doctor since being pregnant with twins is a high-risk pregnancy. Your MFM specialist will also help manage any of these issues:

Your MFM specialist can also help if:

  • You need special tests or procedures
  • You or your babies develop problems while you are pregnant
  • Your babies have a birth defect or other abnormal finding on ultrasound

Working with an MFM specialist during your pregnancy can help you feel confident that you and your babies are getting the best care possible.

How an MFM Doctor Works With Your Pregnancy Team

Depending on your situation, the MFM doctor may manage your care directly or consult with other providers on your team. An MFM specialist may:

  • Provide most of your prenatal care
  • Work hand-in-hand with your OB, family doctor, or midwife to co-manage your care
  • Consult with your midwife or doctor as needed
  • Consult and work with neonatologists or other pediatric experts to make sure your babies get the care they need

An MFM specialist will work closely with you and your regular health providers to see you safely through labor and delivery.
