Infancy antibiotics use does not lead to childhood obesity

The biggest study of its kind has found taking antibiotics in infancy DOES NOT lead to childhood obesity, despite previous studies suggesting a link. Antibiotics change the bacteria in the gut - and studies on animals suggested this could lead to weight gain. But a study led by Professor Wayne Cutfield from The Univeristy of Auckland's Liggins Institute, looked at the use of antibiotics during pregnancy and the first two years of life and also a child's BMI at four-years-old, and found that's not the case. Professor Cutfield began by explaining to First Up's Lydia Batham why they looked into the association.
