Smoking Overweight Mothers while Pregnant: Ill Effects to the Fetus Heart

Recommend to others!

Expectant mothers, who are obese and smoke as well during their pregnancy, put at risk at the development of heart of their baby, found by the research which published this study online in the Journal “Heart”.  The most general defects found in the babies at the time of their birth are congenital heart abnormalities and around 8 in every 1000 babies are affected with this problem. A probable case is discovered in 15 cases only. The researchers based their findings on analysis of 800 babies as well as fetuses that were born with abnormalities of congenital heart and no additional defects amid the years 1997 and 2008.

These children were then compared with nearly 322 fetuses and children who were born with abnormalities of chromosomal but with no heart defects. The study throws light on an enhanced damaging impact for the combination of smoking and obesity against just one of these factors alone, with due consideration of significant factors like mother’s educational attainment and alcohol consumption. Expectant mothers who were both obese with BMI of 25 or more and smoked, had 2.5 times greater probability of giving birth to a child who might suffer from congenital heart defect.

American Pregnancy Association says that “Third-hand smoke can cause serious issues for babies and young children. Recent studies are now linking babies and young children exposed to third-hand smoke have increased risk of asthma, breathing problems, learning disabilities and cancer. Third-hand smoke is the contamination that that occurs from cigarette smoking. These toxins build up over time, one cigarette at a time. You cant see third-hand smoke like you can first and second hand smoke, but it has serious affects just the same. Third-hand smoke is made up of gasses and toxins that remain in peoples clothes and hair, in carpet, furniture and drapes. Because babies and young children’s brains are still developing, they are much more susceptible to any levels of toxins. And because young children are often closer in proximity to the surfaces that absorb these layers of toxins (and they are also more likely to put their mouths on room surfaces), this makes these contaminated surfaces more dangerous to them than adults. Pregnant women and young children should try to stay away from any places where smoking occurs.”

The results of the study indicate that expectant mothers smoking and being obese might both are concerned in the similar pathway which causes abnormalities of congenital heart defects, as per the researchers. However the precise mode of action is not clear, even then they lay stress to the abnormality in plasma cholesterol, which is connected independently with smoking and obesity. This then leads to increased level of bad cholesterol and decreased level of good cholesterol. The findings by the authors and researchers put forward and add to the progressing body of evidence for the association amid obesity and smoking during pregnancy with stunted growth, miscarriage, damaged heart and pre-mature birth of the child.
