The New IBS
From functional disorder to biological networks
IBS was long described as a "functional" disorder, defined by what tests could not find. Advances in neurogastroenterology, mucosal immunology and microbiome science are replacing that view with one of overlapping biological pathways.
This monograph walks through the emerging model, the communication between gut, brain, immune system, intestinal barrier and microbiome, and offers wording a healthcare professional can use when a patient's tests are reassuring but their symptoms are real.
Inside this monograph

- Five emerging paradigm shifts in how IBS is understood
- The overlapping pathways: gut-brain signalling, immune activation, barrier function and the microbiome
- A useful patient explanation for "your tests are normal"
- Where microbiome science in IBS is heading
