Final answer:
Drinking alcohol during pregnancy can result in Fetal Alcohol Syndrome (FAS), a condition with physical, cognitive, and behavioral defects. There is no safe level of alcohol consumption during pregnancy, so complete abstinence is the safest choice.
Step-by-step explanation:
Drinking alcohol during pregnancy can damage the developing embryo and fetus, resulting in Fetal Alcohol Syndrome (FAS). This condition is characterized by a range of physical and cognitive defects including distinct facial features such as a thin upper lip, small eye openings, and a smooth philtrum, as well as developmental delays, and behavioral issues. There is no known safe amount, frequency, or time to consume alcohol during pregnancy, and thus it is recommended to completely abstain from alcohol to prevent the risk of FASDs, which are entirely avoidable.
