Every parent hopes their baby will be perfect. Unfortunately, in approximately 5% of pregnancies, a fetal problem is detected. Many of these problems are very minor, however more serious conditions may also be identified. Types of fetal abnormalities include:
Structural fetal problems can affect any system from head-to-toe. They are usually first detected at the 18-20 week fetal anatomy scan-indeed this is the main purpose of this scan. Fetal chromosomal problems are usually detected earlier in a pregnancy, following a screening test (commonly the nuchal translucency or NIPT test). Fetal growth problems (where the baby is too small or too big) are generally only diagnosed in the 3rd trimester.
