How does one trigger fetal alcohol syndrome?

By steady drinking: There is no known safe amount of alcohol intake during pregnancy. Most experts believe that consistent drinking of one or more drinks per day, or periodic binge drinking can result in fetal alcohol syndrome. This can occur in any trimester, not only the first.

Alcohol consumption: There is no known "safe" amount or type of alcohol that can be consumed during pregnancy. There is also no known safe time. The sure way to avoid fetal alcohol syndrome is to avoid using any alcohol during pregnancy.

Dose dependent: The original FAS cases were found in offspring of skid row alcoholics in France in the 1950's.Many died of their disease within a year.Their kids had the most intense effects. Since that time we know the alcohol turns to formaldehyde in the fetus, injuring tissue.Brain effects include ADHD/ADD.There is no safe dose, although casual use is hard to pin to specific injury.

The only cause of : FAS is fetal exposure to alcohol during pregnancy. Alcohol is a teratogen, a substance that disrupts fetal development, causing birth defects. Binge drinking, having 4 or more standard drinks for a woman, is especially harmful The brain & other organs start forming 3 weeks after conception, often before a woman knows she is pregnant. Thus, social drinking + an unplanned pregnancy can cause FAS.
