Pregnant women are strongly urged not to drink alcohol during pregnancy.
Drinking alcohol while you are pregnant has been shown to cause harm to a baby inside the womb and may lead to long-term medical problems in the child after birth.
When a pregnant woman drinks alcohol, the alcohol travels through her blood and into the baby's blood, tissues, and organs. That means when a pregnant mom has a glass of wine, her baby has a glass of wine, too.
Drinking alcohol can harm the baby's development. 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 is very dangerous, and can sometimes lead to lifelong damage.
Dangers of Alcohol During Pregnancy
Drinking a lot of alcohol during pregnancy can lead to fetal alcohol syndrome in the baby. Fetal alcohol syndrome refers to a group of birth defects found in children born to mothers who drink too much alcohol. Symptoms can include:
These medical problems are lifelong and can range from mild to severe.
Complications seen in the infant may include:
How Much Alcohol is Dangerous?
There is no known "safe" amount of alcohol use during pregnancy. Alcohol use appears to be the most harmful during the first 3 months of pregnancy; however, drinking alcohol anytime during pregnancy can be harmful.
Alcohol includes beer, wine, wine coolers, and liquor.
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 find out. While it is unlikely that the occasional drink you took before finding out you were pregnant will harm your baby, the sooner you stop drinking alcohol, the healthier your baby will be.
Try replacing alcoholic drinks with their nonalcoholic counterparts: for example, you might opt for a nonalcoholic pina colada instead of the real thing.
If you cannot control your drinking, avoid eating or drinking around people who are drinking alcohol.
Pregnant women with alcoholism should join an alcohol abuse rehabilitation program and be checked closely by a health care provider throughout pregnancy.
