Antibiotics given in infancy may have adverse impact on adult gut health

Preterm and low birth-weight babies are routinely given antibiotics to prevent⁠—not just treat⁠—infections, which they have a high risk of developing. A new study published in The Journal of Physiology has found that early life exposure to antibiotics in neonatal mice has long-lasting effects on their microbiota, enteric nervous system, and gut function. This could mean that babies given antibiotics may grow up to experience gastrointestinal issues.
