(Alcohol in Pregnancy; Drinking Alcohol During Pregnancy; FAS)
Fetal alcohol syndrome (FAS) belongs to a group of disorders called fetal alcohol spectrum disorder. It is caused when a woman drinks alcohol during pregnancy. The alcohol can cause birth and developmental defects in the baby. These defects make up FAS.
Alcohol travels through this path and affects the baby's development, particularly the heart and brain.

Alcohol can cross from the mother's blood to the baby's blood. It is passed through the placenta. Even a small amount of alcohol can damage the fetus. It is not known how much alcohol it takes to cause defects. The risk increases with moderate to heavy drinking and with binging. But, even social drinking may pose a danger.
Any type of alcohol, including beer and wine, can cause birth defects.
Factors that increase your baby's chance of getting FAS:
- Unplanned pregnancy or failing to recognize pregnancy and continuing to drink
- Lack of knowledge about the risks of drinking while pregnant
- Low socioeconomic status
Birth and developmental defects depend on when the fetus was exposed to alcohol and how much alcohol was consumed.
Babies with FAS may have the following physical symptoms:
- Low birth weight
- Small size and delayed growth
- Small head
- Small eyes
- Short, flat nose
- Flat cheeks
- Small jaws
- Unusually shaped ears
- Thin upper lip
- Shaking or tremors
- Sight and hearing problems
- Heart defects
- Small, abnormally formed brain
- Vision problems
- Ear infections
As the infant grows, other symptoms may develop, including:
- Difficulty eating and sleeping
- Delayed speech
- Learning disabilities
- Intellectual disability
- Poor coordination
- Behavior problems
