What does an estimated fetal weight (EFW) below the 10th percentile indicate?

An estimated fetal weight (EFW) below the 10th percentile indicates intrauterine growth restriction (IUGR). This condition suggests that the fetus is not growing as expected for its gestational age due to various factors that can hinder its growth and development. IUGR can arise from maternal conditions such as high blood pressure, nutritional deficiencies, or placental insufficiency, among others.

Recognizing IUGR is crucial for managing pregnancy, as it may lead to increased risks for complications during delivery and potential health issues for the newborn. Monitoring and additional assessments will often follow to determine the best course of action for both the mother and the fetus. Understanding EFW in this context is vital for identifying at-risk pregnancies and ensuring timely interventions.
