title: [Post-infectious functional gastrointestinal disorders: from the acute episode to chronicity].
abstract: Functional gastrointestinal disorders (FGID) form a major part of gastroenterology practice. Several studies have reported the development of post-infectious irritable bowel syndrome (PI-IBS) after acute gastroenteritis (AGE). Non-gastrointestinal (GI) infections may increase the risk of developing IBS. There are also data showing that a GI infection may trigger functional dyspepsia (PI-FD). The possible development of PI-IBS or PI-FD depends on factors related to both the infection and the host. Microinflammation has been found in patients with post-infectious FGID. Studies performed in animal models show that infection and acute inflammation permanently change gastrointestinal motility and sensitivity. The role of AGE in the development of FGID is important not only because this entity provides an excellent natural model for pathogenic study but also because it provides an opportunity for preventive action.
