ToggleSummary
- An anomaly scan helps find major structural abnormalities in the baby during mid-pregnancy. However, some issues may arise or become noticeable later as the baby grows.
- Complications like fetal growth restriction, placental issues, heart defects, brain conditions, and amniotic fluid concerns can develop after a normal anomaly scan.
Introduction
The anomaly scan, usually done between 18 and 22 weeks, is an important ultrasound that checks the baby’s organs, brain, heart, spine, and limbs for possible abnormalities.
Many parents wonder, Can abnormalities develop after an anomaly scan? Even after a normal anomaly scan, some conditions may develop or become noticeable later as the baby continues to grow.
This is why regular check-ups and follow-up scans are still important during pregnancy.

Can Abnormalities Develop After an Anomaly Scan?
Yes, some abnormalities or pregnancy-related complications can still appear after a normal anomaly scan.
While the scan gives a detailed look at the baby’s development at that stage, the baby continues to grow and change throughout pregnancy.
Why Can Some Abnormalities Appear Later?
As the baby grows, certain conditions may become clearer or appear later. In some pregnancies, complications can develop due to reduced blood flow, placental defects, maternal health conditions like diabetes or high blood pressure, genetic conditions, or infections during pregnancy.
Since important organs continue developing throughout pregnancy, doctors may recommend additional scans later on to monitor the baby’s growth and overall health more closely.
What Types of Conditions May Develop Later?

- Fetal Growth Restriction (FGR): In some pregnancies, the baby may grow slowly.
- Placental Insufficiency: As pregnancy progresses, the placenta may sometimes become less effective in supporting the baby’s growth and development.
- Low Amniotic Fluid Levels: Amniotic fluid levels can reduce later in pregnancy due to placental or fetal health concerns.
- Certain Heart Abnormalities: As the baby’s heart develops further, some heart conditions may become easier to identify.
- Brain or Kidney Concerns: Certain developmental changes involving the brain or kidneys may only appear in later scans.
Does a Normal Anomaly Scan Mean Everything Is Perfect?
A normal anomaly scan is very reassuring and greatly reduces the chances of major abnormalities.
However, some genetic, developmental, or pregnancy-related conditions may only become noticeable later in pregnancy or after birth.
This is why regular antenatal check-ups and follow-up scans are still important even after receiving a normal scan report.
Why Are Follow-Up Scans Important?
These scans help monitor:
- The baby’s growth
- Placental blood flow
- Amniotic fluid levels
- The baby’s position before delivery
Who May Need Closer Monitoring?
Some pregnancies may require closer monitoring to help ensure the health and well-being of both the mother and baby.
- High blood pressure
- Diabetes during pregnancy
- Twin or multiple pregnancies
- Reduced fetal movements
- Previous pregnancy complications
Should Parents Worry After a Normal Anomaly Scan?
Parents do not need to worry if the anomaly scan is normal, as most pregnancies continue without major abnormalities.
Follow-up appointments and scans are simply a routine part of pregnancy care and help doctors continue monitoring the baby’s healthy growth and development.

FAQ
1. Can a baby develop problems after a normal anomaly scan?
Yes, while a normal anomaly scan is reassuring, some conditions or complications may develop later in pregnancy as the baby continues to grow.
2. Are third-trimester scans still important after a normal anomaly scan?
Yes. Third-trimester scans help monitor the baby’s growth, position, fluid levels, and overall well-being later in pregnancy.
3. Can growth restriction appear after the anomaly scan?
Yes, some babies may develop growth restriction later in pregnancy even if the anomaly scan was normal.
4. Do all babies with normal anomaly scans remain healthy throughout pregnancy?
Most pregnancies progress normally after a healthy anomaly scan, but regular follow-ups are still important to monitor ongoing development.
5. Can late pregnancy complications be missed earlier?
Some complications, such as growth issues or placental concerns, may only become noticeable in the later stages of pregnancy.
6. Why do doctors recommend repeat scans after a normal report?
Repeat scans help doctors track the baby’s growth and monitor the health of both the mother and baby throughout pregnancy.
7. Can placental problems develop after the anomaly scan?
Yes, certain placental issues can develop or become more apparent later in pregnancy.
8. Is additional monitoring common in high-risk pregnancies?
Yes, high-risk pregnancies often require extra scans and closer monitoring to ensure the best possible care for both mother and baby.
