What IUGR means in pregnancy

Clinicians may use IUGR, intrauterine growth restriction, or fetal growth restriction when ultrasound measurements suggest that growth needs closer attention. A small baby can be healthy and naturally petite, while restricted growth can reflect reduced support from the placenta, maternal health conditions, or other pregnancy factors. One measurement does not give the whole picture. The team considers growth over time, blood flow findings, fluid around the baby, and the baby's wellbeing.

Attend the recommended appointments and scans so the care team can compare measurements over time. A Growth Scan can assess size, fluid, and related findings. Fetal Heart Monitoring may check how the baby is coping. Keep taking prescribed medicines and tell the maternity team about reduced movement or new symptoms. The plan may be continued observation, extra monitoring, or planning birth when remaining pregnant is less reassuring than delivery.

Contact your maternity service promptly if your baby's movements are less than usual, stop, or change noticeably. Seek urgent assessment for vaginal bleeding, leaking fluid, regular painful contractions, severe headache, visual changes, sudden swelling, or severe upper abdominal pain. These symptoms need assessment because they can signal a pregnancy problem; they do not establish the cause by themselves.

Ask which measurement led to the concern, how growth compares with earlier scans, whether blood flow or fluid is reassuring, how often monitoring is needed, and what findings would change the timing or method of birth.
