The Gut Microbiome and Inflammation
The gut microbiome refers to the trillions of microorganisms living inside the digestive tract. Research continues to show that the microbiome plays an important role in digestion, immune regulation, and inflammation.
In Crohn’s disease and ulcerative colitis, changes in the gut microbiome may contribute to chronic inflammation and immune dysregulation.
Scientists are actively studying:
- microbial diversity
- dietary patterns
- probiotics
- prebiotics
- fiber intake
- inflammatory pathways
and how they may influence IBD symptoms.
