Antibiotics cause weight gain in children

This study at the University of Helsinki suggests that the use of antibiotics in young children may alter the natural populations of gut microbes and leave them vulnerable to weight gain and asthma in later childhood. 236 children were studied with a median age of five and this research backs earlier research on mice. The change in composition of the microbiome was found to have a long-term impact on metabolism that persisted even when the population of gut microbes had returned to normal several weeks later.
