The UK's Chief Medical Officers recommend that, if you are pregnant or planning to get pregnant, it's best not to drink alcohol. This will keep the risks to your baby to a minimum. Drinking in pregnancy can lead to long-term harm to the baby. The more you drink, the more the risk.
When you drink alcohol, it passes through the blood through the placenta to the baby.
A baby's liver is one of the last organs to develop and doesn't mature until later in pregnancy. Your baby therefore cannot process alcohol as well as you can and too much exposure affects their development.
Drinking alcohol, especially in the first three months of pregnancy, increases the risk of miscarriage, premature birth and your baby having a low birth weight. Heavy drinking throughout pregnancy can cause your baby to develop a serious health condition called fetal alcohol syndrome.
