Why Tobacco Use and Pregnancy do not go together?

Posted on May 18, 2009 in Latest News

The dangers of tobacco use among women during pregnancy are so real that these cannot be ignored any more. Those who are looking to deliver healthy babies need to be more conscious as smoking during pregnancy can cause increased number of miscarriages, preterm births, stillborns and deaths after birth.

In the United States and other industrialized countries, nearly 18% of women do regular smoking. This number is significantly low, nearly 8% in developing countries because of severe cultural constraints.

What are the Effects of Tobacco during Pregnancy?
It is suggested that tobacco exposure is related with a number of complications during pregnancy.

These can cause:

Intrauterine growth restriction
Placenta previa
Placental abruption
Premature rupture of membranes
Sudden infant death syndrome (SIDS)

How Tobacco Exposure Causes Problem in Developing Placenta?

Listed are the ways tobacco causes complications to placenta:

Effect of Nicotine in Tobacco: Nicotine, the natural ingredient in tobacco causes spasms in arteries including those which are responsible for supplying blood to the placenta. Arterial spasm reduces the supply of oxygen and much needed nourishments to the placenta. This can result in underweight babies.
Effect of Carbon monoxide on Placenta: During smoking, oxygen is slowly replaced by carbon monoxide in the blood. Placenta growing inside the womb might try to compensate this oxygen loss by producing extra red blood cells. This can make the blood become thicker and cut off the supply of blood to the vital organs of the baby, thereby resulting in neonatal death.
Long Term Effects of Tobacco on the Baby: During late stage of pregnancy, nicotine exposure can cause damage to baby’s rapidly developing nerve cells. Laboratory studies on animals have shown that even small dose of nicotine exposure during pregnancy result in poor functioning of brain, learning problem, etc. It is assumed that premature babies can suffer from learning disabilities all through their life because of usage of tobacco by their mothers.

Smoking and Pregnancy

According to Centers for Disease Control and Prevention, mothers who smoke during pregnancy have 30% more chance of giving birth to prematurely born babies. These babies can weigh on an average 200 gms less than babies born to non-smoking mothers. They are 1.4 to 3.0 times more like to die of Sudden Infant Death Syndrome (SIDS). However, if pregnant mothers stop smoking even by the end of second trimester, there is no more likely risk of giving birth to low-birthweight babies as non smoking mothers.
