Drinking alcohol in pregnancy

You don't have to stop having fun now you're pregnant - but there are a few things you'll have to give up. Alcohol is one of these things, because it can damage your growing 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 expecting.

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.

What could happen if I drink heavily?

Drinking heavily (more than six units a day) throughout pregnancy is dangerous. It can cause your baby to develop a serious condition called fetal alcohol syndrome (FAS).

Children with FAS can have:

  • Restricted growth
  • Facial abnormalities
  • Heart defects
  • Learning and behaviour disorders

FAS can be caused by binge drinking (drinking more than five standard drinks or 6 units in a single session) or regularly drinking more than one or two units once or twice a week. The more you drink, the higher the risk.

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.

What if I had a drink 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 drunk only small amounts of alcohol before you knew you were pregnant or during pregnancy.
