AbstractAbdominal pain is associated with many gastrointestinal dysfunctions, such as irritable bowel syndrome (IBS), functional dyspepsia, and inflammatory bowel disease (IBD). Visceral hypersensitivity is a key reason for development of abdominal pain that presents in these gastrointestinal disorders/diseases. The pathogenesis of visceral hypersensitivity is complex and still far from being fully understood. In animal studies, visceral hypersensitivity has been linked to several early‐life adverse (ELA) events. In humans, IBD, functional dyspepsia, and IBS can have adult onset, though the adverse events that lead to visceral hypersensitivity are largely uncharacterized. In this issue of the journal, Aguirre et al. report the interesting finding that epigenetics underlies the effects of ELA events on visceral hypersensitivity. This mini‐review examines models of ELA events leading to visceral hypersensitivity and the potential role of epigenetics, as reported by Aguirre et al. and others.
