Fetal growth is among the most important of parameters monitored during the course of prenatal care. Although the majority of pregnancies proceed with no complications in fetal growth, a small number will show evidence of growth restriction. A variety of conditions are associated with or increase the risk for fetal growth restriction (FGR). These factors are summarized in Table 7.1. This chapter will review risk factors for FGR, as well as complications, tracking of potential FGR, and management.
