An article by researchers from the University of Edinburgh (UK) is published in the journal PLOS Medicine. According to statistics, in 2016 in countries of Western Europe, with the help of cesarean section, 24.5% of the total number of people in the world appeared, in North America – 32%, and in South America – 41% of newborns. Moreover, more and more operations are performed without medical indications, simply because for women, this method of delivery seems less painful and risky than natural vaginal births.
In order for future mothers to make a more informed decision about how their birth will take place, the researchers analyzed 79 previous studies on the long-term consequences of caesarean section compared to conventional births. In total, nearly 30 million people took part in them.
As a result, children born with caesarean were about 50% more likely to develop obesity before the age of five and the risk of developing asthma before the age of 12 compared to their peers who were born with vaginal births. Scientists do not exclude that an increased tendency to obesity and asthma may be due to the fact that, since in the case of a caesarean child does not pass through the maternal pathways, he does not receive from the mother any important intestinal bacteria. Because of this, the body of the child is a metabolic disorder and the immune system.
As for the long-term consequences of cesarean for mothers, there are both positive and negative ones among them. Positive consequences include a lower risk of urinary incontinence and pelvic lowering compared with vaginal delivery. However, the negative consequences were much greater, and they are more serious.
So, after Caesarean, the chances of a new pregnancy are reduced by about a third compared to natural childbirth. If pregnancy after cesarean has come, it is associated with an increased risk of miscarriage and stillbirth, as well as such pathologies as placenta previa (placenta previa), placenta accreta (ingrown placenta) and placental abruption. Such complications can be associated with damage to the uterus during surgery or an infection that developed after it, researchers suggest.
