Background The Rome III criteria subdivide functional dyspepsia ( FD ) in the epigastric pain syndrome ( EPS ) and the postprandial distress syndrome ( PDS ) based on the frequency of the symptoms to optimize the diagnostic and therapeutic approach. However, it is unclear to which extent the frequency of the symptoms is related to their severity. Our aim was to explore the frequency and severity of dyspeptic symptoms and their relationship in FD patients. Methods Functional dyspepsia patients fulfilling the Rome III diagnostic completed a questionnaire that evaluated the frequency and severity of FD symptoms. The concordance between the severity and frequency categories was analyzed by means of spearman correlation and the concordance correlation coefficient (ρ c ). Key Results In the entire patient cohort ( n =421), the classification of symptoms severity and frequency showed good concordance for all symptoms. In the EPS subgroup ( n =….), the symptom severity and frequency score of epigastric pain showed a poor correlation ( r =.28; ρ c =0.07). The PDS subgroup ( n =…) showed a good correlation for most of the symptoms. Due to its limited occurrence in this group, the correlation of the severity and frequency scores for epigastric pain is of little relevance ( r =.79; ρ c =0.58). The overlap EPS ‐ PDS group showed good correlation for most of the symptoms, except for epigastric pain (pain r =.24; ρ c =0.09). Conclusions & Inferences We conclude that the information given by the assessment of frequency and severity of PDS symptoms is comparable and hence one of the scores sufficiently identifies symptom pattern in PDS patients. In EPS patients, both the symptom frequency and severity should be taken into account as two separate entities.
