The effects of antibiotics on the gut microbiome can persist for weeks, months, and in some cases, even years.
A narrative review examined how antibiotic use can alter the gut microbiota across different stages of life.
Antibiotics target harmful bacteria, but they can also reduce beneficial microbes and overall microbial diversity. This disruption, known as dysbiosis, can affect immune function, metabolism and the ability of pathogenic or antibiotic-resistant species to establish themselves.
The review found that these effects can differ throughout the lifespan. Antibiotic exposure during pregnancy and infancy may alter the developing microbiome, while in adults some microbial changes can remain long after a course of antibiotics has ended.
Antibiotic-induced changes may also affect bile acid metabolism, short-chain fatty acid production and other pathways involved in insulin sensitivity, weight regulation and susceptibility to infection.
The researchers also discuss probiotics and prebiotics as potential strategies for supporting microbial recovery, while highlighting the need to better understand how to protect the microbiome alongside appropriate antibiotic use.
