Story summary
- Antibiotic use significantly alters gut microbiome composition for four to eight years, according to a Uppsala University study in Sweden.
- The analysis used data from nearly 15,000 adults and found clindamycin and fluoroquinolones had the strongest effects, while penicillin V had minimal impact.
- The findings urge careful antibiotic prescribing to mitigate long-term risks, including obesity and type 2 diabetes, and to favor treatments less disruptive to gut health.
