[Functional dyspepsia: definition, classification, clinical and therapeutic management].
Dyspepsia is a very common syndrome characterized by pain and/or discomfort of the upper abdomen. Sometimes, an organic disease causes this syndrome (organic dyspepsia); more frequently, there are no known diseases (functional dyspepsia). These latter conditions are identified by exclusion. The pathogenesis of this syndrome is yet to be clarified. Currently, functional dyspepsia is classified in ulcer-like dyspepsia, dysmotility-like dyspepsia and nonspecific dyspepsia, in which symptoms do not clearly fit into any of the above categories. The current guidelines for the management of "uninvestigated dyspepsia" suggest testing for Helicobacter pylori infection and relative treatment if positive. A gastroscopy should be performed in case of persistence of symptoms to discriminate between the organic and functional forms. In the latter, to optimize patient management, it is necessary to find the exact subgroup. Antacids, H2-receptor antagonists and proton pump inhibitors have been demonstrated to be useful in ulcer-like dyspepsia. Prokinetic agents are more effective in the dysmotility-like dyspepsia. Further studies will be necessary to confirm the efficacy of emerging therapeutic strategies.
