Antibiotic usage can damage the protective mucus layer in the gut

Repeated antibiotic use can cause defects in the gut's protective mucus barrier, even months after treatment. This is due to changes in the microbiota or direct effects of antibiotics on the mucus layer. The findings suggest that antibiotics should be used responsibly to prevent long-lasting damage.
