What is Maternal Fetal Medicine (MFM)?

Maternal Fetal Medicine (MFM) is a sub-specialty of obstetrics that focuses on managing health concerns of the mother and unborn babies prior to, during and shortly after an un-routine pregnancy.

Who should see a MFM specialist?

Certain medical conditions and advanced maternal age may put you, or your developing fetus or both, at higher-than-normal risk for complications during pregnancy or after.

You may be referred to a MFM specialist for the following reasons:

  • You are 35 years or older
  • Have medical conditions such as high blood pressure, heart or kidney disease, or an autoimmune disorder
  • Have diabetes or develop it during pregnancy (pregnancy induced diabetes)
  • A family history of genetic/hereditary concerns
  • Multiple gestation (twins, triplets, quadruplets)
  • Your pregnancy is not progressing as expected
  • Previous miscarriages, pregnancy complications or preterm delivery (premature birth)
