DefinitionBy Mayo Clinic staff
Fetal alcohol syndrome (FAS) is a condition that results from alcohol exposure during pregnancy. Problems that may be caused by fetal alcohol syndrome include physical deformities, mental retardation, learning disorders, vision difficulties and behavioral problems.
The problems caused by fetal alcohol syndrome vary from child to child, but defects caused by fetal alcohol syndrome are irreversible.
There is no amount of alcohol that's known to be safe to consume during pregnancy. If you drink during pregnancy, you place your baby at risk of fetal alcohol syndrome.
If you suspect your child has fetal alcohol syndrome, talk to your doctor as soon as possible. Early diagnosis may reduce the risk of problems, including learning difficulties and substance abuse.
