Existing evidence implicates the placenta as the origin of some common pregnancy complications. Moreover, some maternal conditions, such as inadequate nutrition, diabetes, and obesity, are known to adversely affect placental function, with subsequent negative impact on the fetus and newborn. The placenta may also contribute to fetal programming with health consequences into adulthood, such as cardiovascular, metabolic, and mental health disorders. There is evidence that altered placental development, specifically impaired trophoblast invasion and spiral artery remodeling in the first trimester, is the origin of preeclampsia. Prenatal care providers who understand the relationships between placental health and maternal‐newborn health can better inform and guide women to optimize health early in pregnancy and prior to conception. This article reviews the current understanding of placental function; placental contributions to normal fetal brain development and timing of birth; and impact of maternal nutrition, obesity, and diabetes on the placenta.
