maternal-fetal medicine

Also: MFM, perinatologist, high-risk obstetrics

A subspecialty of obstetrics for higher-risk pregnancies. Your provider may bring in one of these specialists for complex health needs.

In plain words

Maternal-fetal medicine is a specialty for pregnancies that carry higher risk. The doctors who practice it train for years after their ob-gyn residency. They are sometimes called perinatologists. They help with conditions such as diabetes, heart disease, high blood pressure, or a known health condition in the baby. Before pregnancy, they can help decide who needs specialty input and who can go ahead with routine care. You may meet one through a referral from your ob-gyn or . Seeing one does not mean something is wrong. It means your team wants extra planning for your health and your baby's.

The deeper version

Maternal-fetal medicine is a subspecialty of obstetrics recognized by the American Board of Obstetrics and Gynecology, practiced in close relationship with the Society for Maternal-Fetal Medicine (SMFM). Its includes preconception risk assessment, fetal anomaly and growth surveillance, antenatal testing, and management of high-risk conditions such as pregestational diabetes, chronic hypertension, and multiple gestation. ACOG Committee Opinion 762, Prepregnancy Counseling (2019), describes the risk stratification that decides when specialty input is needed before conception. The field's main debate concerns how far risk-based referral should reach, given uneven referral capacity and the fact that many flagged risks are modest in absolute terms.
