What is Fetal Alcohol Syndrome?

WebMD Feature

Like any syndrome, fetal alcohol syndrome (FAS) is a group of signs and symptoms that appear together and indicate a certain condition. In the case of FAS, the signs and symptoms are birth defects that result from a woman's use of alcohol during her pregnancy. Among their symptoms, children with FAS may grow less quickly than other children, have facial abnormalities and have problems with their central nervous systems, including mental retardation.

In the United States, FAS is one of the leading causes of birth defects and is thought to be the most common cause of preventable mental retardation. Each year between 5,000 and 12,000 American babies are born with the condition. FAS is sometimes called fetal alcohol abuse syndrome.
