How Much Alcohol Is Too Much?
It's clear that abusing alcohol during pregnancy is dangerous, but what about the occasional drink? How much alcohol constitutes too much during pregnancy?
No evidence exists that can determine exactly how much alcohol ingestion will produce birth defects. Individual women process alcohol differently. Other factors vary the results, too, such as the age of the mother, the timing and regularity of the alcohol ingestion, and whether the mother has eaten any food while drinking.
Although full-blown FAS is the result of chronic alcohol use during pregnancy, FAE and ARND may occur with only occasional or binge drinking.
Because alcohol easily passes the placental barrier and the fetus is less equipped to eliminate alcohol than its mother, the fetus tends to receive a high concentration of alcohol, which lingers longer than it would in the mother's system.
Mothers who drink during the first trimester of pregnancy have kids with the most severe problems because that is when the brain is developing. The connections in the baby's brain don't get made properly when alcohol is present. Of course, in the early months, many women don't even know they're pregnant.
It's important for women who are thinking about becoming pregnant to adopt healthy behaviors before they get pregnant.
Women who abstain from alcohol in early pregnancy may feel comfortable drinking in the final months. But some of the most complex developmental stages in the brain occur in the second and third trimesters, a time when the nervous system can be greatly affected by alcohol. Even moderate alcohol intake, and especially periodic binge drinking, can seriously damage a developing nervous system.
Prevention Is the Key
FAS can be completely prevented by not drinking any alcohol during pregnancy.
