Antibiotics, the immune System & mental health

Consensus AI reports added May 3, 2026
"Research links antibiotic exposure—especially in pregnancy and early life—to later neurodevelopmental and psychiatric outcomes, largely via effects on the gut microbiota–brain axis, but findings are small in size and often inconsistent."
"There is robust evidence that antibiotic use—especially when broad-spectrum or administered early in life—can cause lasting immune dysregulation through both direct cellular toxicity and indirect disruption of the gut microbiome. This increases susceptibility to infection, impairs vaccine responses, raises risk for autoimmune/allergic/metabolic diseases, and complicates management during critical illness."
