Babies born by caesarean section are twice as likely to be obese because of differences in the bacteria in their gut, researchers have suggested.
The researchers calculated that it would mean the average three year old would be 0.5lb or 0.23kg heavier if they were born by caesarean when compared with those born naturally.
It is thought differences in the bacteria in the gut between those born by caesarean and those born naturally is the reason but further research is needed, the experts said.
Around one in four women give birth by caesarean section in
Britain, most of which are emergencies.
Women who have Caesareans are normally given antibiotics and this could influence gut bacteria in the baby as well as transit through the birth canal.
It may be that gut bacteria influence the development of obesity by increasing energy extracted from the diet, and by stimulating cells to boost insulin resistance, inflammation, and fat deposits, it was suggested. ...
