The therapy of functional dyspepsia: an update

Functional dyspepsia (FD) is a common disorder of the gut-brain interaction (previously named functional gastrointestinal disorders). Recent data evaluate its prevalence to 7% worldwide. FD is classified into epigastric pain syndrome (EPS) and PDS (PDS). While the diagnosis of FD is standardized thanks to the work of the Rome Foundation committees, the therapy is far from being satisfactory. A recent European guide found few strong recommendations, reflecting the lack of sufficient data for high levels of evidence. This review is presenting possibilities of management of FD. Therapeutic indications should target the main symptoms and be proportionate to the severity.
