Fetal growth restriction (FGR) occurs when a fetus does not grow at the expected rate during pregnancy. This can lead to a lower birth weight and may increase the risk of complications for both the baby and the mother. FGR can be caused by various factors, including maternal health issues, placental problems, or genetic conditions. Monitoring fetal growth is essential for early detection of FGR. Healthcare providers often use ultrasound imaging to assess the size and development of the fetus. If FGR is diagnosed, doctors may recommend closer monitoring or early delivery to ensure the best possible outcomes for the baby and the mother.
