Neurogastroenterology is defined as neurology of the gastrointestinal tract, liver, gallbladder, and pancreas and encompasses control of digestion through the enteric nervous system, the central nervous system, and integrative centers in sympathetic ganglia ( 15 ). When I first discovered the field of neurogastroenterology, I had a ton of questions! It can develop in babies during pregnancy (congenital intestinal pseudo-obstruction), or as a result of a bowel abnormality. Stress-induced changes in intestinal motility have been recognized since 1902 when Cannon, the discoverer of barium meal technique for studying gastrointestinal motility, noted changes in the flow of intestinal contents in cats confronted by growling dogs (08). Kim S, Kwon SH, Kam TI, et al. If you have nervous system abnormalities (neurological disorder), your brain and gut may not communicate with each other properly and you may develop chronic abdominal pain, where recurring abdominal pain is experienced over an extended period of time. This alarmingly unique perspective would likely help dispel the belief that IBS is a diagnosis of exclusion or a trashcan diagnosis.Though, this perception of IBS is still quite popular in the IBS community.
