Fetal Alcohol Syndrome (FAS) is caused by a woman drinking alcohol during pregnancy. It is completely preventable but is also the leading cause of preventable mental retardation. FAS can cause growth delays, brain abnormalities, and facial features like a smooth philtrum and small eye openings. Children with FAS often experience developmental delays and need lifelong support services. Improving awareness of the dangers of drinking during pregnancy and consistency in diagnosis can help improve outcomes for children with FAS.
