Drinking alcohol during pregnancy; Fetal alcohol syndrome - pregnancy; FAS - fetal alcohol syndrome
Pregnant women are strongly urged not to drink alcohol during pregnancy.
Drinking alcohol while pregnant has been shown to cause harm to a baby as it develops in the womb. Alcohol used during pregnancy may also lead to long-term medical problems and birth defects.
When a pregnant woman drinks alcohol, the alcohol travels through her blood and into the baby's blood, tissues, and organs. Alcohol breaks down much more slowly in the baby's body than in an adult. That means the baby's blood alcohol level remains increased longer than the mother's. This can harm the baby and can sometimes lead to lifelong damage.

Drinking a lot of alcohol during pregnancy can lead to a group of defects in the baby known as fetal alcohol syndrome. Symptoms can include:
These medical problems are lifelong and can range from mild to severe.

HOW MUCH ALCOHOL IS SAFE?

One drink is defined as:
How much you drink is just as important as how often you drink.
DO NOT DRINK DURING PREGNANCY
Women who are pregnant or who are trying to get pregnant should avoid drinking any amount of alcohol. The only way to prevent fetal alcohol syndrome is to not drink alcohol during pregnancy.
If you did not know you were pregnant and drank alcohol, stop drinking as soon as you learn you are pregnant. The sooner you stop drinking alcohol, the healthier your baby will be.
Choose nonalcoholic versions of beverages you like.
If you cannot control your drinking, avoid being around other people who are using alcohol.
