FASD is a condition that may occur when a fetus is exposed to alcohol prenatally. Prenatal Alcohol Exposure (PAE) can occur at any point during the pregnancy, including before the pregnancy is detected. Alcohol is included within the group of substances called teratogens, or poisons, meaning that it is a substance that can cross to the developing fetus and cause harm at any stage of pregnancy. There is no known safe amount or time to consume alcohol during pregnancy, and the UK’s Chief Medical Officer’s advice is that those who are pregnant, or planning a pregnancy, should abstain from alcohol.
