[Prevalence of delayed gastric emptying of solids in functional dyspepsia and its relationship to symptoms].

UNLABELLED: The relationship between functional dyspepsia and delayed gastric emptying of solids is still unclear. This study evaluated the prevalence of delayed gastric emptying of solids in functional dyspepsia patients and its relationship to dyspeptic symptoms.

MATERIAL AND METHOD: 142 patients with functional dyspepsia were prospectively assessed, the solid gastric emptying was measured using 13C-acid octanoic breath test and the severity of six dyspeptic symptoms (postprandial fullness, early satiety, bloating, abdominal discomfort, nausea and vomiting) was scored.

RESULTS

Gastric emptying of solids was delayed in 45 (31.7%) dyspeptic patients. Multivariate analysis showed that the presence and severity of nausea and vomiting were associated with delayed solid gastric emptying (p < 0.05). Female gender was also associated with the risk of delayed gastric emptying (p < 0.05).

CONCLUSIONS

A subset of functional dyspepsia patients has delayed gastric emptying of solids. Female sex, the presence and severity of nausea and vomiting are independently associated with delayed gastric emptying of solids in these patients.
