Antibiotics Impact on Gut Microbiome

Antibiotics Impact on Gut Microbiome examines how antibiotic use, while essential for treating bacterial infections, can significantly disrupt the balance of the gut microbiota. Antibiotics often act broadly, eliminating not only harmful pathogens but also beneficial bacteria, leading to a condition known as dysbiosis. This imbalance can reduce microbial diversity, impair digestive function, and weaken the gut’s protective barrier.

This session will explore the short-term and long-term consequences of antibiotic exposure, including antibiotic-associated diarrhea, increased susceptibility to infections such as Clostridioides difficile, and potential links to chronic conditions like obesity, allergies, and autoimmune diseases. Special attention will be given to vulnerable populations such as infants and the elderly, where microbiome disruption can have more pronounced effects.

Experts will discuss strategies to mitigate antibiotic-related damage, including the use of probiotics, prebiotics, dietary interventions, and timing of supplementation to support microbiome recovery. The session will also highlight responsible antibiotic use, antimicrobial stewardship, and ongoing research into targeted therapies that minimize collateral damage to beneficial microbes.
