A growth scan is a type of ultrasound examination performed during pregnancy to assess the growth and development of the fetus. Typically, these scans are conducted in the second and third trimesters, although they may be done earlier in high-risk pregnancies or if there are concerns about the baby’s growth. The primary objective of a growth scan is to evaluate the baby’s size, weight, and overall well-being.

Why Are Growth Scans Necessary?

1. Monitoring Fetal Growth: Growth scans are essential for tracking the baby’s growth rate over time. They help detect any abnormalities or deviations from the expected growth curve.
2. Assessing Amniotic Fluid Levels: These scans can also evaluate the levels of amniotic fluid surrounding the baby, ensuring it’s adequate for proper fetal development.
3. Detecting Birth Defects: While not the primary purpose, growth scans may sometimes reveal certain structural abnormalities or birth defects in the fetus.
4. Identifying Pregnancy Complications: Growth scans play a crucial role in identifying potential complications such as intrauterine growth restriction (IUGR), which occurs when the baby fails to grow at a normal rate inside the womb.

When Are Growth Scans Typically Done?

• Late Second Trimester: Growth scan may be scheduled around 28-32 weeks to monitor the baby’s growth and assess the placenta’s function.
• Third Trimester: Growth scans may be repeated periodically during the third trimester to continue monitoring fetal growth and well-being.

Common outcomes of growth scans include:

• Normal Growth: The baby’s measurements fall within the expected range for gestational age, indicating healthy growth and development.
• Concerns or Abnormalities: If the scan reveals any deviations from the norm, further evaluation may be recommended to determine the cause and potential implications for the pregnancy.
