The manifestation of specific growth, mental, and physical birth defects associated with the mother's high levels of alcohol use during pregnancy . Causes, Incidence and Risk Factors Alcohol use or abuse by the pregnant woman subjects her to the same range of risks that alcohol has in the general population. However, it poses extreme and unique risks to the fetus and is associated with fetal alcohol syndrome. Timing of alcohol use during pregnancy is also of importance. Alcohol use during the first trimester is more damaging than during the second trimester which is, in turn, more damaging than use in the third trimester.
Alcohol ingested by a pregnant woman easily passes across the placental barrier to the fetus.
Because of this, drinking alcohol can adversely affect the development of the baby. The incidence of fetal alcohol syndrome varies from 1 out of 1,500 to 1 out of 600 live births. This wide range is related to differences in drinking practices. However, increasing amounts appear to cause increased problems in a linear fashion. Symptoms Consumption of alcohol by a pregnant woman may be the first indicator of potential fetal alcohol syndrome.
