Antibiotics Are the Gut Microbiome’s Biggest Disruptor, Doctors Warn
Gastroenterologists warn antibiotics are the single biggest disruptor to the gut microbiome, though other meds like proton pump inhibitors, laxatives, NSAIDs, and certain cardiac drugs can also alter gut bacteria for years after use; probiotics are not reliably protective, though Saccharomyces boulardii may reduce the risk of C. difficile diarrhea; if you must take antibiotics, focus on fiber-rich foods to support gut health.
