Smoking alters fetus DNA

When a woman is pregnant, it is common knowledge that she should not engage in drinking alcohol or smoking. There is new evidence that discloses the fact that when a pregnant women smokes, the fetus' DNA is altered. Scientists also found that some new development-related genes were caused by the mother's smoking habit.

In a study conducted by the American Journal of Human Genetics, blood samples were taken from newborn's and compared to babies of nonsmoker mothers. The DNA of the smoke babies had over 6,000 areas in which the DNA was modified from the tobacco. About 3,000 could be directly linked to lung and nervous system developmental problems as well as birth defects and cancers. These modified pieces of DNA were still present in older children of smoking mothers. 
It is truely disgusting for a mother to knowingly put her unborn child at risk for many diseases and health complications down the road. These children are born with health complications which can last a lifetime.  However, these studies bring the science community much closer into evalutating exactly which genes are affected and potentially how to treat children of mothers who smoked while pregnant.

  1. A friend was just telling me today that she read this recently in an article online so I made it a point to read all the links. I enjoyed reading this and I'm glad more studies are being done on unborn fetuses so they can help shed light on how important and delicate these little lives are! I hope they reach major news sources as it is incredibly important for future mothers and fathers to know how to care for their babies properly and make sure they grow to be as healthy as possible.
