It is very common amongst expectant mothers to have a third-trimester growth scan, between 28 and 32 weeks gestation, to check that their baby is growing the way it should be. Here we look at some of the frequently asked questions surrounding this scan such as why it is needed, what happens during and what can the results tell you.

Why do you need to have a growth scan at 32 weeks?

As mentioned, this scan is conducted to ensure that your baby is developing and growing as expected. Hospitals may offer this scan as a routine or may recommend it if they suspect too much amniotic fluid. As a result of this scan, you will be able to see:

  • The position of your baby in the womb
  • If your baby is smaller or larger than expected

What happens during your 32-week growth scan?

Your growth scan will be conducted in the exact same way as all your other ultrasound scans, using gel on your stomach and a transducer device which allows you to see an image of your baby. Here, your sonographer will be able to:

  • Evaluate the volume of amniotic fluid surrounding your baby
  • Measure your baby’s head, abdomen and thigh bone
  • Measure the blood flow around your baby’s body

What does the 32-week growth scan tell you?

The 32-week growth scan looks at your baby’s wellbeing by measuring its biophysical profile. During the scan, the sonographer will be looking to see if your baby:

  • Opens and closes its hands
  • Stretches and flexes
  • Moves its arms and legs frequently
  • Makes breathing movements

From this scan, the sonographer will be able to see if your baby is small for gestational age (smaller than expected), possibly due to a lack of the necessary nutrition through the placenta or restricted levels of oxygen. Or if your baby is larger than expected, which is usually not a medical concern. If for some reason your baby is significantly larger than expected, you may need to get tested for gestational diabetes, a measure for the levels of glucose in your blood. High levels could result in birthing complications and enhance the likelihood of induced labour or a caesarean. In regards to the position of your baby, this scan will show whether your baby is head down (normal position), feet first (breech position) or laying sideways (transverse position). Your doctor may advise you to have an ECV (External Cephalic Version) if your baby is in breech position. This is a completely safe procedure whereby a surgeon pushes down and around on your abdomen in order to turn your baby into a normal head-down position for birth.
