Fetal alcohol syndrome (FAS) is growth, mental, and physical problems that may occur in a baby when a mother drinks alcohol during pregnancy.
Alcohol in pregnancy; Alcohol-related birth defects; Fetal alcohol effects; FAS; Fetal alcohol spectrum disorders; Alcohol abuse - fetal alcohol; Alcoholism - fetal alcohol
Using alcohol during pregnancy can cause the same risks as using alcohol in general. But it poses extra risks to the unborn baby. When a pregnant woman drinks alcohol, it easily passes across the placenta to the fetus. Because of this, drinking alcohol can harm the unborn baby.
There is no "safe" level of alcohol use during pregnancy. Larger amounts of alcohol appear to increase the problems. Binge drinking is more harmful than drinking small amounts of alcohol.
Timing of alcohol use during pregnancy is also important. Drinking alcohol is likely most harmful during the first 3 months of pregnancy. But drinking alcohol any time during pregnancy can be harmful.
A baby with FAS may have the following symptoms:
Women who are pregnant or who are trying to get pregnant should not drink any amount of alcohol. Pregnant women with alcohol use disorder should join a rehabilitation program and be checked closely by a health care provider throughout pregnancy.

The outcome for infants with FAS varies. Almost none of these babies have normal brain development.
Infants and children with FAS have many different problems, which can be difficult to manage. Children do best if they are diagnosed early and referred to a team of providers who can work on educational and behavioral strategies that fit the child's needs.
Call for an appointment with your provider if you are drinking alcohol regularly or heavily, and are finding it difficult to cut back or stop. Also, call if you are drinking alcohol in any amount while you are pregnant or trying to get pregnant.
Avoiding alcohol during pregnancy prevents FAS. Counseling can help women who have already had a child with FAS.
Sexually active women who drink heavily should use birth control and control their drinking behaviors, or stop using alcohol before trying to get pregnant.
