Caesareans are changing the evolution of the woman's body

Childbirth is a very complicated process that often requires a surgical intervention to get the child out of the womb. These practices are known as cesareans and in recent years they have grown considerably in developed countries as indicated by the World Health Organization, WHO.

As indicated by this body, the Caesarean section It is a good method to achieve a safe delivery in certain situations as they prevent risks for both the mother and the child. However, in births without threats, this practice is not recommended at all, and even so, the number of these interventions has multiplied in recent decades. A fact that is contributing to the evolution of the body of women is changing.


Smallest pelvis

To check whether the increase in caesarean sections was having any effect on the woman's body, a group of researchers from the University of Vienna analyzed the deliveries and their types over the years. In this way they found that the number of non-vaginal births had gone from 3% in the 60s to between 3,3% and a 3,6% nowadays.

This means that today a greater number of mothers need this intervention to give birth. The reason? The cesareans. As these researchers indicate in the past, if a woman of narrow hips There was a high risk that both she and her daughter would die during the delivery.


However, the introduction of cesareans caused the gene of narrow hips to be transmitted from mother to daughter. This, in turn, caused this woman to give birth to new girls with the same characteristics, increasing the number of pregnant women with small pelvis and that therefore they needed this type of intervention.

Evolutive trend of babies

Not only are mothers changing. More and more children are born bigger, in fact the babies' heads are bigger than the rest of the primates. This causes the risk of death during the delivery increase as the output space is lower in these cases and these genes are not designed to change.

However, cesareans are making these children survive the birth. Reason why these genes can pass to the next generations and larger children can gestate in the Mother's belly, making a cesarean section necessary again. This, together with the smaller pelvis of the mothers, makes this intervention essential.
