Smoking during pregnancy – Protect your baby from tobacco smoke


Smoking causes cancer, heart disease, and other major health problems. It also makes it harder for a woman to get pregnant. In addition, smoking during pregnancy causes other problems, because reduces the amount of oxygen available to the baby and, besides, the nicotine and other poisons that the mother inhales from cigarettes (each of which contains over 4,000 chemicals) are carried through the bloodstream and go directly to the baby. Smoking during pregnancy increases the heart rate of the baby (because cigarettes restrict the oxygen supply, and his/her heart has to beat harder when the mother smokes), causes premature birth, low birth weight (which can lead to problems during labour and makes it more likely the baby will be sick), and respiratory problems. Besides, women who smoke during pregnancy are more likely than other women to have a miscarriage.

Regular exposition to second-hand smoke during pregnancy can have the same consequences as smoking.

Smokers have lower serum levels of omega-3 fatty acids. In pregnant women who smoke, omega-3 supplementation may have a protective effect, since it is associated with a lower risk of spontaneous preterm delivery and low birth weight.

But this should not be an excuse to postpone quitting smoking. It is never too late to quit. The health of your baby should be a good enough reason to make it.
