Effects of Smoking In Pregnancy
Protecting your baby from tobacco smoke is one of the best things you can do to give your child a healthy start in life. It’s never too late to stop smoking. Every cigarette you smoke contains over 4,000 chemicals, so smoking when you are pregnant harms your unborn baby. Cigarettes can restrict the essential oxygen supply to your baby, so their heart has to beat harder every time you smoke.
Benefits of stopping smoking in pregnancy
you will have fewer complications in pregnancy
you are more likely to have a healthier pregnancy and a healthier baby
you will reduce the risk of stillbirth
you will cope better with the birth
your baby is less likely to be born too early and have to face the additional breathing, feeding and health problems that often go with being premature
your baby is less likely to be born underweight: babies of women who smoke are, on average, 200g (about 8oz) lighter than other babies, which can cause problems during and after labour, for example they are more likely to have a problem keeping warm and are more prone to infection
you will reduce the risk of cot death, also called sudden infant death (find out about reducing the risk of cot death)
Stopping smoking will also benefit your baby later in life. Children whose parents smoke are more likely to suffer from asthma and other more serious illnesses that may need hospital treatment.
The sooner you stop smoking, the better. But even if you stop in the last few weeks of your pregnancy this will benefit you and your baby.
Second-hand (passive) smoke harms your baby
If your partner or anyone else who lives with you smokes, their smoke can affect you and the baby both before and after birth. You may also find it more difficult to stop if someone around you smokes.
Second-hand smoke can also reduce birthweight and increase the risk of cot death. Babies whose parents smoke are more likely to be admitted to hospital for bronchitis and pneumonia during the first year of life. More than 17,000 children under the age of five are admitted to hospital every year because of the effects of second-hand smoke.
