How the Gut and Brain Interact in Inflammatory Bowel Disease: Causes and Treatments

Inflammatory Bowel Disease (IBD) involves complex interactions between genetic factors, environmental triggers, and microbial imbalances.

• The gut microbiome, primarily consisting of Firmicutes and Bacteroidetes, is essential for intestinal health and immune regulation.
• Dysbiosis in the microbiome is marked by a decrease in beneficial bacteria that produce short chain fatty acids and an increase in harmful species.
• This imbalance can lead to increased mucosal inflammation and the release of cytokines, which may negatively affect mental health via the gut-brain axis.
• Emerging links suggest that microbial metabolites, vagal tone, and the hypothalamic-pituitary-adrenal axis create a feedback loop that may sustain inflammation and influence mood.
• Current treatments for IBD include dietary changes, manipulative therapies, fecal microbiota transplantation, and phage therapy.
