A woman who drinks alcohol while she is pregnant may harm her developing baby (fetus). Alcohol can pass from the mother's blood into the baby's blood. It can damage and affect the growth of the baby's cells. Brain and spinal cord cells are most likely to have damage.
The term fetal alcohol spectrum disorder (FASD) describes the range of alcohol effects on a child. The problems range from mild to severe. Alcohol can cause a child to have physical or mental problems that may last all of his or her life.
The effects of alcohol can include:
Although the risk is higher with heavy alcohol use, any amount of alcohol may affect your developing baby. Heavy drinking (5 or more drinks on at least one occasion) during pregnancy can severely affect a developing baby.
You can prevent FASD by not drinking at all while you are pregnant. That is what many doctors suggest.
The effects that alcohol has on a developing baby depend on:
Try to talk openly with your doctor if you have had alcohol while you're pregnant. The earlier you tell your doctor, the better the chances are for your child.
If your doctor knows to look for FASD-related problems while you're pregnant, he or she can watch your baby's health both before and after birth. And the doctor will know to do more tests, if needed, as your child grows.
If you think you might have a drinking problem, talk with your doctor, counsellor, or other support person. Doing this can help you to see and address how alcohol may affect many parts of your life, including your pregnancy.
Signs of FASD don't always appear at birth. A doctor may be able to spot severe alcohol effects (fetal alcohol syndrome, or FAS) in the child at birth. But less severe effects, such as behaviour or learning problems, may not be noticed until the child is in school.
Sometimes the doctor can find severe problems before the baby is born. If your doctor knows about your alcohol use, he or she can order a test (ultrasound) to look for signs of FAS in your baby, such as heart defects or growth delays. The cause of problems that are found during the test may not be clear. But the findings alert the doctor to any special care a baby may need after he or she is born.
Caring for a child born with alcohol effects takes patience. Help for your child may include extra support in school, social skills training, job training, and counselling. Community services may be able to help your family handle the costs of and emotions from raising your child.
Finding alcohol effects early, even if they are mild, gives a child the best chance to reach his or her full potential in life. Finding the problem early may help prevent problems in school and mental health problems, such as substance use problems, depression, or anxiety.
There is no treatment that can reverse the impact of alcohol on your baby's health. And there's no treatment that can make the effects less severe.
