Did you know that 9% of pregnant women smoked during pregnancy?
Did you know that smoking can harm your fetus to his life, after birth?
Did you know that passive smoking can also affect you and your unborn child?
Smoking while pregnant exposes you and your unborn child to an increased risk of serious health problems.
If you smoke while pregnant you are at increased risk of a wide range of problems including miscarriage and premature labour.
You are twice as likely to give birth to a low birth weight baby compared to a mother who does not smoke. Low birth weight babies are at greater risk of death and are more vulnerable to infection, breathing difficulties and long-term health problems in adulthood.
The more cigarettes you smoke during your pregnancy, the greater your risk of complications and having a low birth weight baby. But cutting down the number of cigarettes you smoke does not reduce most of the risks to you and your baby. Stopping smoking completely early in your pregnancy best protects the health of you and your baby. But quitting at any time helps reduce harm.
Pregnancy complications from smoking
Some of the pregnancy complications more commonly experienced by women who smoke include:
Ectopic pregnancy – this is pregnancy outside the uterus, usually in the fallopian tube
Fetal death – death of the baby in the uterus (stillbirth)
Spontaneous abortion – known as miscarriage
Problems with the placenta, including early detachment from the uterine wall and blocking the cervical opening (placenta previa)
Premature rupture of the membranes
Smoking during pregnancy – effects on your unborn baby
If you are pregnant, every time you smoke a cigarette, it reduces oxygen to your unborn baby and exposes them to many toxic chemicals.
Some of the many damaging effects of cigarette smoke on your unborn baby include:
reduced oxygen supply and nutrients due to carbon monoxide and nicotine in tobacco smoke
slower growth and development
increased risk of birth defects such as cleft lip and cleft palate
the baby’s movements are weaker in the womb for at least an hour after smoking each cigarette
impaired development and working of the placenta
harming the development of baby’s brain and lungs.
Smoking and breastfeeding
Breastfeeding has many benefits and helps to protect your child from chest and ear infections, and illnesses of the gut and lungs. Stopping smoking during breastfeeding is very worthwhile.
Some of the problems caused by smoking while breastfeeding include:
Nicotine and some other chemicals in cigarette smoke can pass from you to your baby through your breastmilk.
Smoking can reduce your milk production and the quality of your breast milk.
Smoking while breastfeeding increases your baby’s risk of a range of health problems including colic and disrupted sleep patterns.
Women who smoke are less likely to breastfeed and are more likely to wean their children earlier than mothers who do not smoke.
If you are finding it hard to stop smoking:
Try not to smoke before or during feeds. To give your body the longest time possible to get rid of nicotine from your breastmilk, breastfeed your baby first, then have your cigarette soon after. Do the same if you are using the nicotine lozenge, mouth spray, gum or inhalator to quit.
Don’t smoke near your baby – go outdoors to smoke.
Smoking during pregnancy can cause problems for your child in later life
Smoking during pregnancy can impair your child’s health for years to come. Health effects may include:
higher risk of asthma
low birth weight, which is linked to heart disease, type 2 diabetes and high blood pressure in adulthood
up to three times the risk of sudden unexpected death in infancy (SUDI).
increased risk of being overweight and obese in childhood
increased risk of attention deficit hyperactivity disorder (ADHD).
Pregnancy and stopping smoking
Talk to your maternity care team about how they can help you. You may make a quitting plan together.
If you are finding it tough to stop smoking, don’t despair. It is never too late to stop smoking. Stopping smoking by the fourth month of pregnancy can reduce some of the risks, such as low birth weight and premature birth. Stopping smoking at any time allows oxygen to reach your baby more easily.
