How Antibiotics Weaken Gut Health and Trigger Inflammatory Bowel Disease (IBD)

New findings unveil how antibiotics compromise the intestinal mucus barrier, heightening susceptibility to inflammatory bowel diseases such as Crohn’s and ulcerative colitis.

Employing cutting-edge tools like RNA sequencing and machine learning, the research team emphasizes the urgent need for novel therapies to counteract these harmful effects.

Revolutionary Insights into Antibiotics and IBD Susceptibility

In a pivotal study published on September 11 in Science Advances, Dr. Shai Bel and his team from the Azrieli Faculty of Medicine at Bar-Ilan University have illuminated critical mechanisms by which antibiotics escalate the risk of inflammatory bowel disease (IBD).

Their research reveals that antibiotics compromise the protective mucus layer within the intestine—a breakthrough that has profound implications for understanding the interaction between antibiotic usage and IBD onset.

IBD, which encompasses Crohn’s disease and ulcerative colitis, affects nearly 1% of the global population. Characterized by the degradation of the mucosal barrier—essential for separating the gut microbiome from the immune system—IBD’s exact triggers have long eluded researchers. While prior investigations suggested a link between antibiotics and IBD, the precise mechanisms remained elusive until now.

Antibiotics and Mucus Barrier Compromise

Dr. Bel’s latest study provides a deeper understanding of this relationship. “We’ve found that antibiotic exposure significantly impairs the mucus barrier that normally protects the immune system in the gut from the microbiome,” Dr. Bel remarks. His team’s findings indicate that antibiotics—whether ingested orally or injected—disrupt this critical barrier, enabling bacteria to penetrate and elevating the risk of intestinal inflammation.

Leveraging advanced methodologies like RNA sequencing, machine learning, and precise mucus secretion assessments, the researchers used mouse models to analyze the consequences of antibiotic intervention. Their data reveals that antibiotics inhibit the secretion of protective mucus, allowing bacteria to infiltrate, trigger systemic bacterial antigen replication, and cause ulcer formation—all prominent features of IBD.

A remarkable aspect of this study is the revelation that antibiotics’ impact on the mucus barrier stems not from changes in the gut microbiome but from their direct effects on the mucus-producing cells in the intestinal lining. “This discovery dismantles the long-held belief that antibiotics only harm bacterial populations, not our own cells,” Dr. Bel emphasizes.

The research team now plans to investigate potential treatments aimed at preventing the detrimental influence of antibiotics on mucus production. These findings not only deepen the understanding of IBD but also highlight the broader consequences of antibiotic use on gut health, calling for more cautious application in medical treatments.
