Stress In The Womb

There is a growing awareness that stress in the womb plays a major role in the creation of genetic diseases and the highly sensitive trait.  Maternal stress during pregnancy results in higher levels of testosterone in the body and by extension a fetus. The higher levels of testosterone change brain development increasing the chance of genetic diseases, the highly sensitive trait as well as high creativity and giftedness.

The BBC  Mum’s stress is passed to baby in the womb reported recently about a study in the journal Translational Psychiatry showing that women under the stress of potential violence have children with a genetic change in the glucocorticoid receptor (GR), which regulates the response to stress, making the children more sensitive to stress.

The article discusses how a change occurs in methyation, an important biological process in “gene expression.”  The best lay explanation comes from Discovery. This is their description:

“Methylation is a process by which a gene’s behavior is altered, but the gene itself isn’t changed. This is almost like following all the directions in baking a batch of cookies correctly, except for the oven temperature. Even though all of the ingredients are the same, those cookies won’t bake — or behave — the same way when baked a couple hundred degrees lower than they should be.In methylation,  environmental exposures or different lifestyle choices have the potential to cause methyl groups, which are groups of one carbon and three hydrogens, to land on top of our genes and change how they are expressed. This, in turn, changes the ability of our genes to share the directions they contain for making our bodies’ proteins.”

Apparently, stress in the womb affects the methylation process during pregnancy, altering gene expression.  Methylation seems to be a major factor in the biochemical processes responsible for a fetus becoming a highly sensitive person.

This is just one study, but it points to an increasing awareness of the impact of stress in the womb in the creation of highly sensitive people.  It is an important tool for developing approaches to minimize genetic diseases of all kinds and shows us how genetic mutations and environmental factors can create unintended results.
