A new study finds that babies born by Caesarean section are more likely to struggle with their weight later in life. Researchers at the Imperial College of London studied 150,000 births.
They found that C-section babies were 25-percent more likely to be heavier as adults. The study author says the findings suggest not having a natural birth may effect a baby's metabolism.
Professor Neena Modi says, "we need to be exposed to the bacteria that come from mother which that baby may not be exposed to if it is born by Cesarean section."
Researchers say other factors may also play a role in C-section babies gaining weight later on, including the mother's weight, age and life style. Previous research has shown C-section babies may have a higher risk for asthma and childhood diabetes.
About a third of babies in the United States are born by C-section.
