Passive Smoking And Its Effects On Pregnancy

Exposure to tobacco smoke affects all stages of human reproduction. Tobacco smoking affects both male and female fecundity. Maternal cigarette smoking is associated with increased risks for ectopic pregnancy, premature rupture of membranes, abruptio placentae, placenta previa, miscarriage, stillbirth, preterm birth, low birth weight and congenital anomalies such as cleft lip.

After birth, the risk for sudden infant death syndrome (SIDS) is increased among the offspring of women who smoked during or after pregnancy. Additionally, maternal exposure to secondhand smoke (SHS) in pregnancy has also been associated with a modest reduction in birth weight, and can increase the risk of low birth weight for the fetus, and hypertension for the mother. People are advised to quit smoking when they conceive.

However, according to studies, merely leaving smoking is not enough to counter the effects of cigarette exposure. Many women get exposed to second-hand smoke. This might by through friends, and family members or the residue cigarettes leave behind.  These types of indirect contact with cigarettes can also have detrimental effects on the health of you and your baby. ( Pregnancy period is defined as ‘from the first antenatal care contact up to six weeks postpartum’).
