Senior Honors Theses
Irritable bowel syndrome (IBS) is a disease of the gastrointestinal tract affecting approximately 11-21% of people worldwide (Xiao et al., 2021). This research focuses on the dysregulation of gut homeostasis in IBS and explains how the pathophysiology of the gut is controlled by the bidirectional brain-gut axis. The mechanisms of the brain-gut axis consist of neuro-immune cross talk, neuro-hormone cross talk, microbiome-gut signaling, and the HPA-axis. Each of these contribute to one or more of the possible phenotypes of gut pathophysiology, which could include intestinal permeability, visceral hypersensitivity, and motility disturbance (Xiao et al., 2021). Stress is also an important …
