Drinking alcohol in pregnancy

Experts can’t be sure exactly how much alcohol, if any, is safe during pregnancy. That’s why their advice is to avoid alcohol completely to reduce potential harm to your baby.

How can alcohol harm my unborn baby?

Most women give alcohol up completely in pregnancy because this is the safest way. When you drink, alcohol passes from your blood through the placenta and to your baby. There is no known safe level for drinking during pregnancy, so the safest approach is not to drink at all while you're pregnant and if you are trying for a baby

It is particularly advised not to drink alcohol in the first three months of pregnancy as this is a time of huge growth and development.

What could happen if I drink heavily?

Drinking in pregnancy can lead to long-term harm to the baby and the more you drink, the greater the risk.

Getting drunk and/or drinking every day are especially dangerous.

Drinking more than the recommended amount of alcohol at any stage during pregnancy is linked to the following:

What is foetal alcohol syndrome?

Foetal alcohol syndrome (FAS) is the name given to problems that are found in children whose mothers drank heavily during pregnancy. These include facial abnormalities, heart defects, poor growth and severe mental and developmental problems.

What if I drank alcohol before I knew I was pregnant?

If you drank a lot before you knew you were pregnant and are worried about the effect this may have on your baby, talk to your midwife or GP.

They will probably reassure you that the risk to your baby is small if you weren’t a regular heavy drinker. You can stop drinking completely now that you know you’re pregnant.

The risk of harm to the baby is likely to be low if you were not binge drinking or regularly drinking over the recommended amount.

What if I need help to stop drinking?

If you drink heavily and you think you may have problems stopping, talk to your doctor or midwife.

This is because you may have withdrawal symptoms. These can include delirium tremens (DTs), and you will need help to manage them.

The health team caring for you during your pregnancy can give you advice and support. You can also contact Drinkline, a free and confidential helpline, on 0300 123 1110 (weekdays 9am - 8pm, weekends 11am - 4pm).

Is my drinking is out of control?

Some women know they are drinking too much but don't feel able to talk about it. It's easy to feel guilty or ashamed because you know you shouldn’t be drinking alcohol in pregnancy.

Everyone who cares for you during your pregnancy wants you to be well and to have a healthy baby. Cutting down or stopping on your own can be difficult, and you may need help.

Talk to your doctor or midwife - they won't judge you and they can put you in touch with more support if you need it.
