Through your pregnancy a few simple cells will grow to form your baby. Organs like the heart, lungs, and brain go through intense periods of development. You can imagine how important it is to have the right building blocks for all of this growth. Nutrients and oxygen that support a growing fetus are passed from mother to fetus through an organ called the placenta.
Unfortunately dangerous substances like drugs, alcohol , and chemicals from recreational smoking can also pass through the placenta to your baby. Chemicals from smoke are absorbed into the blood from the mom’s lungs. Many of the chemicals are not only toxic but also interfere with the delivery of oxygen and nutrients to the baby. These chemicals can cause serious and chronic illnesses in adults and children. In a developing baby, the chemicals can also impair development. Some health issues may be seen at birth while others can develop later in a baby’s life. Fortunately, it is never too late to give your baby the best start to a healthy life.
Researchers do not yet fully understand how every chemical in smoke affects a growing baby. But they do know that the health risks are high. If you smoke, you are more likely to have pregnancy complications that put both you and your baby at risk. Complications include:
Also smoking while pregnant puts your baby at a higher risk for serious complications such as:
By now you probably know that tobacco products contain nicotine, which is an addictive substance. When you first quit smoking, your body goes through withdrawal. You may develop physical symptoms such as dizziness, depression, headaches, tiredness, and sleep problems. The first few days after you stop smoking can be tough. The good news is that the withdrawal effects are temporary. Keep this in mind as you get through the first week. It will get better.
If you have cravings, distracting yourself can help you overcome them. For example when you have a craving, don’t immediately reach for a cigarette; instead try these distractions:
Talk to others that have successfully quit and ask how they did it. (The resources listed below also have success stories.) Some programs and smoking cessation tools can also help you gradually decrease your nicotine levels. However, certain smoking cessation products like nicotine gum or patches may not be safe while pregnant. Talk to your doctor to find the right balance.
Remember that while you are pregnant, your baby is also exposed to nicotine through the placenta. If you smoke while pregnant, your baby will have nicotine withdrawal symptoms after he or she is born. This can make your baby more jittery, nervous, and harder to soothe.
The earlier you stop smoking the better for you and your baby. It is never too late to stop. Even shortly after stopping your body will begin to recover:
As you get healthier, so does your baby.
Make a plan to quit smoking:
Remember, if you are making changes to give your baby a healthy start, those around you should help out as well. Secondhand smoke you inhale introduces the same type of chemicals. If you live with a smoker ask the person to stop or smoke outside.
If you do stop smoking during pregnancy, congratulations! Your hard work has given your baby a healthier start and improved your own health. Keep it up even after your baby is born. Smokers that breastfeed continue to pass chemicals like nicotine on to the baby through breast milk. Babies are also very susceptible to secondhand smoke.
If you tried to quit but started smoking again, try again. Identify what it was that triggered your return to smoking and make a new plan around it. It may take more than one try but keep at it and soon you’ll be enjoying clear deep breaths while you hold your new baby.
