The chapters in this book are based on the Visceral Pain conference in Adelaide, Australia, under the auspices of the International Federation for Neurogastroenterology and Motility in 2021. This is one of the hottest fields of science and includes mechanisms involving how the microbiome communicates with the brain and how, when disordered, these mechanisms contribute to clinical diseases such as Irritable Bowel Syndrome and Inflammatory Bowel Disease. Researchers from around the globe presented their latest findings as a review of the current state of the art in the field from both the clinical and scientific points of view. These systems are now appreciated as being critical for shaping our well-being and their disorders underlie chronic clinical conditions of significant morbidity and mortality. The author team includes long-established authorities who significantly contributed to the advances in visceral pain research over the past two decades and the new generation thatwill continue to contribute to advancing our understanding of the field.
