How Does Alcohol Cause Fetal Alcohol Syndrome Problems?
How Does Alcohol Cause Fetal Alcohol Syndrome Problems?Answer: Alcohol in the mother’s blood crosses the placenta freely and enters the embryo or fetus through the umbilical cord. The exact mechanism(s) by which alcohol damages the fetus and critical times of exposure are not known; however, exposure during the first trimester results in the structural defects (i.e., facial changes) characteristic of FAS, whereas the growth and CNS disturbances could occur from alcohol use during any time in pregnancy.
