Fetal alcohol syndrome, or FAS, is a collection of congenital defects, such as ventricular septal defect or atrial septal defect, facial abnormalities and other developmental problems caused by exposure of the fetus to alcohol during pregnancy. Alcohol consumption during the first trimester is most hazardous.
Fetal alcohol syndrome, or FAS, is a collection of birth defects due to a woman consuming alcohol during pregnancy. The alcohol easily passes across the placenta to the fetus and can harm the baby's development.
A baby with FAS may have decreased muscle tone, poor coordination, delayed development and growth, heart defects and facial abnormalities. No safe level of alcohol during pregnancy has been set, and drinking during the first three months or trimester is considered the most harmful. While the outcome for affected babies varies, normal brain development is not common.
