Fetal Alcohol Syndrome
(Alcohol in Pregnancy; Drinking Alcohol During Pregnancy; FAS)En Español (Spanish Version)
When a women drinks alcohol during pregnancy, it can cause birth and developmental defects in the baby. This is called fetal alcohol syndrome.
The condition is caused by alcohol that crosses from the mother's blood to the baby's blood through the placenta. Even a small amount of alcohol can damage the fetus. Doctors do not know 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 can cause birth defects, including beer and wine.

A risk factor is something that increases your baby's chance of getting fetal alcohol syndrome. Tell your doctor if you have any of these:
- Unplanned pregnancy
- Failure to recognize early pregnancy and continuing to drink
- Lack of knowledge about the risks of drinking while pregnant
- Advanced maternal age
- Low socioeconomic status
Birth and developmental defects depend on when the fetus was exposed to alcohol.
Babies with fetal alcohol syndrome may have the following physical symptoms:
- Low birth weight
- Small size and retarded 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
- Minor joint defects that may restrict movement
- Teeth prone to cavities
- Vision problems
- Ear infections
As the infant grows, other symptoms may develop, including:
- Difficulty eating and sleeping
- Delayed speech
- Learning disabilities
- Attention deficit hyperactivity disorder
- Lower IQ
- Mental retardation
- Poor coordination
- Behavior problems
- Poor ability to control impulses
- Problems getting along with other children
Children do not outgrow these effects. Teens and adults often experience social and emotional problems. They may develop secondary conditions, which include:
The doctor will ask you about your alcohol intake while pregnant, assess the child's growth, and perform a physical exam. The diagnosis is based on:
- History of alcohol use
- Characteristic facial appearance
- Slow growth
- Nervous system problems
Some children with this condition do not have the facial symptoms. Their condition is described as "fetal alcohol effect."
An early diagnosis can help your child get the services he needs.
There is no specific medical treatment for this condition. Early intervention is helpful, as well as a supportive, nurturing home.
Professional support helps a family cope with caring for a child with birth defects. Services include respite care and parent training. You can learn ways to handle behavior problems and stress management techniques.
Programs designed to meet your child's needs improve learning. For example, messages may need to be repeated. Tasks may need to be broken down into smaller steps.
- Provide consistent direction and structure.
- Keep to routines.
- Establish simple rules, limits, and consequences.
- Praise desired behaviors.
- Do not threaten. Violence or abuse increases the risk the child will learn to react in a similar fashion. Your child may need special training to learn ways to handle anger.
- Avoid drinking alcohol if you are pregnant or trying to get pregnant. Also, take folic acid to prevent other birth defects.
- Avoid heavy drinking when not using birth control. Damage can occur before you even know you are pregnant.
- Seek help from a doctor if you cannot stop drinking.
- Use birth control until you are able to quit drinking.
