How smoking affects an unborn child
Smoking cigarettes during pregnancy more damage to the fetus and the mother. When cigarette smoke enters the body, some of the additives are quickly vented. However, other chemicals remain in the body and moving in the placenta. The baby is then exposed to two types of cigarette smoke in the womb of a smoker. First, the mainstream smoke that comes from the mother directly and through the placenta, and secondly, the smoke in the air which affects the second hand baby. Unless the mother quits smoking after the baby is born, it will continue to be affected and damaged by secondhand smoke.
Nicotine in cigarettes combined with higher levels of carbon monoxide and lower levels of oxygen causes movement of the baby to slow. He will move more slowly while his heart beats faster to try to take more oxygen. This stress causes the fetus to grow more slowly and less completely a baby in the womb of a non-smoking mother. In addition to slower development, the baby has 29% more likely to be born with too much, too little or webbed fingers and toes (see References). Smoking during pregnancy has also been proven to cause asthma, learning disabilities, lower IQ and lungs that can not fully function without the use of a respirator after birth. There is also a double or triple the risk of sudden infant death syndrome (see References).

Besides delaying the development of infants in the womb, smoking during pregnancy also causes the death of ectopic pregnancy the fetus, and complications of childbirth extremely dangerous. The chance of having a baby stillborn or dies during the first week after birth increases to 33% when the mother smoked during pregnancy, and 25% false rate increased layers (see References). Premature birth and low birth weight are also common. Placenta previa is related to smoking as well, and causes the placenta to block the cervix, making it the most painful delivery and dangerous because it puts the life of the mother and child at risk.
