Smoking and drinking during pregnancy



Give your baby the healthiest start in life

It’s well known that smoking and drinking during pregnancy can affect your baby’s health. But it’s not just mums-to-be who need to make sacrifices – smoking near a pregnant partner can be damaging too. Giving up cigarettes and cutting down on alcohol isn’t easy, but it will mean you feel healthier and fitter when your baby arrives. Our Careline team are here to help 24/7 if you need some support.

Why give up smoking1?

Smoking is known to have detrimental effects on an unborn baby’s health, so it’s a good idea for both you and your partner to give up.

When your pregnant partner is exposed to passive smoke, your baby takes in a range of harmful chemical substances, including:

  • Nicotine – known to constrict blood vessels, affecting the uterine and placental blood flow and increasing your baby’s blood pressure and heart rate
  • Carbon monoxide – binds to haemoglobin in the blood, meaning that blood cells carry less oxygen resulting in a low birthweight
  • Tar – a cancer-causing substance that can irritate the lungs

Of course, once your baby has arrived, any smoke they inhale will have the same negative effect on their health. So by giving up smoking now, your baby will be getting a healthier start in life, and you might be able to completely kick the habit.

Why give up alcohol?

Sometimes your partner might have had a drink early on in pregnancy before realising they’ve conceived. But after they’ve discovered they are pregnant it’s recommended they give up completely.

“The Department of Health recommends that if you’re pregnant, or planning to become pregnant, you should avoid alcohol altogether. But, if you do opt to have a drink, you should stick to no more than one or two units of alcohol (equivalent to one or two small glasses of wine) once or twice a week to minimise the risk to your baby2.”

Whilst your alcohol consumption won’t have a direct effect on your child, by giving up or cutting down on alcohol you’ll be offering some valuable moral support for your pregnant partner.

If you’re cutting down, rather than fully giving up, it’s a good idea to stick to the recommended daily alcohol intake, which is 3–4 units for men or 2–3 for women.

Next Steps

Here are some handy tips for giving up smoking and drinking4:

  • Set a date to quit and stick to it. It helps to have a fixed goal
  • Exercise can help curb cravings
  • Fidget and chew gum. Keeping your mouth and hands busy will stop the habitual reach for the cigarettes
  • List the reasons you are quitting and cutting down, and look back at them when you’re tempted
  • Think positive; it makes all the difference

If you’re finding it difficult to quit smoking, you can also call your local NHS Stop Smoking Service and Stop Smoking Helpline on 0300 123 1044 (open Mon–Fri, 9am–8pm and Sat-Sun, 11am–4pm).
