Baby on the Way? Keep Smoking at Bay.

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.

Risks for Mother and Baby

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:

Nixing the Nicotine Need

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, do not immediately reach for a cigarette; instead try these distractions:

  • Participate in activities. Go for a walk or try relaxation techniques like deep breathing.
  • Drink water.
  • Nibble on a healthy snack like vegetables or fruits.
  • Suck on a hard piece of candy.
  • Call someone who supports you in your goal to quit.
  • Think about your reasons for quitting (your baby, financial reason, your own health). Everyone is motivated by personal reasons. Find what works for you.
  • Have a hobby handy that you can do right away whenever a craving hits. Some hobbies to try are crossword puzzles, reading a novel, and knitting.

Talk to others that have successfully quit and ask how they did it. 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 she is born. This can make your baby more jittery, nervous, and harder to soothe.

It’s Never Too Late

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:

  • Within minutes your heart rate and blood pressure drop.
  • Within 12 hours carbon monoxide levels in your blood return to normal (carbon monoxide decreases oxygen level in your body; it is a chemical that is also found in car exhaust).
  • Within just a couple of weeks your circulation and lungs improve their function.

As you get healthier, so does your baby.

Make a plan to quit smoking:

  • Start with a quit date.
  • Look for situations that tend to trigger smoking and avoid them or make plans for distraction.
  • Assess your emotional reasons for smoking. You may actually find that smoking adds to your problems instead of providing relief. For example:
    • You may smoke to relax, but it may actually be more stressful to find time, location, and money to smoke.
    • You may smoke as a way to socialize, but smoking is now less socially accepted and you will often have to spend time away from the group when you smoke.

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.

Keeping the Air Clear

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 will be enjoying clear deep breaths while you hold your new baby.
