Visceral sensitivity is a normal physiological response of digestive tract hollow structures. Hypersensitivity and hypo sensitivity have been involved in the genesis of most functional disorders. Currently correction or modulation is usually based on pharmacological efforts which seek to eliminate or alleviate symptoms as- sociated with these disorders. Functional dyspepsia is a poorly understood physiopathological disorder still associated with diagnostic misunderstandings and permanently changing defi nition, classifi cation and thera- peutic approaches. Given the prevalence of this entity it seems useful to review the current conceptualization of dyspepsia and the role of visceral sensitivity as the physiological timer of motility in its physiopathology.
