This creates a reduction in the placental blood f pathetic, and further reductions in oxygen delivery. As well nicotine interferes with the ability of the placenta to feed the baby the nutrients it requires. Therefore the babies growth is slowed down. Carbon monoxide causes growing cells to be starved of oxygen, and effects the brain. This stool lead to a low birth weight and higher c hance of the baby dying at birth. Smoking is the single largest modifiable( changeable) risk factor in fetal growth retardation. agnate smoking during pregnancy is in addition associated with genetic defects as well as an increased incidence of congenital malformations such as cleft palates, microcephalus, and clubfoot.
