Section 4- TobaccoNo Smoking Allowed!

Tobacco Use• After smoking a cigarette, several thousand toxic

chemicals enter the bloodstream and are sent to the cells all over the body.

• Nicotine, Carbon Monoxide and many other chemicals can be found in every body tissue of a smoker:

– Eyes, Hair, Semen, and Vaginal Secretions

• Most are now aware of the link between smoking and respiratory problems such as lung cancer.

• Smoking can also have an affect on reproduction and pregnancy.

Effects on Reproduction• Men who smoke may have decreased

sperm production.

• Smoking may affect the function and quality of the sperm and the egg.

• Women who smoke have a harder time conceiving a child than non-smokers.

How Does Smoking Affect Pregnancy?

• Nicotine constricts the blood vessels in the uterus, decreasing the blood flow to the fetus.

• This increases blood pressure, and may cause the fetus to have trouble breathing.

• Deficiency of oxygen and nutrients slows cell growth and can affect mental development.

• The fetus will secrete nicotine and other chemicals into the amniotic fluid that surrounds them causing continued exposure.

How Does Smoking Affect Pregnancy?

• Infant low-birth weight and failure-to-thrive.

• Increased risk for miscarriage and stillbirth.

• Women who smoke during pregnancy are at a higher risk for premature labor and placenta disorders.

• Smoking is the leading cause for low-birth rate which is linked to retarded growth in all areas of development.

• If smoking is stopped by 16 weeks many times birth weight returns to normal.

What About Second Hand Smoke?

• Any exposure to the chemicals found in smoke can affect the fetus.

• It is difficult to study the impact of second hand smoke on a fetus because it is hard to accurately measure the exposure.

• The higher the mother’s exposure the more likely it is to affect the fetus- be very careful if you live with smokers.

Effects of Smoking After Delivery

• Mother’s who smoke during pregnancy and while breastfeeding place their babies at higher risk for Sudden Infant Death Syndrome (SIDS).

• Infants and women are at higher risk for ear infections, respiratory illness, asthma, and colds due the build up of smoke particles in the lungs.
