Consequences of IUGR: what to know

Fetal growth restriction means a baby is not growing as expected in the womb. Some babies are naturally small, while others grow slowly because of placental, maternal or fetal factors. The concern is not size alone: clinicians also assess growth over time, blood flow and the baby’s wellbeing.

Reduced placental support can affect oxygen and nutrient delivery. This may lead to closer observation, reduced amniotic fluid, changes in blood-flow measurements or a decision that birth is safer before the due date. After birth, a small baby may need help with temperature, blood sugar or feeding.

Keep scheduled antenatal visits and scans. A Growth Scan can compare measurements over time, while Fetal Heart Monitoring can assess the baby’s heart pattern when closer surveillance is needed. Your team may also check blood pressure, urine and placental blood flow.

Follow advice about movement, medicines and appointments, and ask how to monitor your baby’s usual movements. If early birth becomes advisable, the team will explain the timing, induction or caesarean considerations, and newborn care arrangements.

Contact your maternity unit immediately if your baby’s movements are reduced or noticeably different, or if you have vaginal bleeding, leaking fluid, regular painful contractions, severe headache, visual changes or sudden swelling. Do not wait for the next appointment when these symptoms occur.

Ask what measurements are changing, whether blood flow and fluid are reassuring, and how often monitoring is needed. Discuss the signs that would prompt birth, whether Induction of Labour is suitable, and what support your baby might need after delivery.
