OBJECTIVE: Hypersensitivity to gastric distension has been reported in functional dyspepsia (FD). The aim of this study was to assess the perception to gastric distension and its relationship to specific symptoms using the water load test (WLT) in FD and gastroesophageal reflux disease (GERD).
MATERIAL AND METHODS: A 5-min WLT was used to evaluate sensitivity of gastric distension in 47 FD and 61 GERD subjects, and 49 healthy controls (HC). A visual analogue scale (VAS) measuring symptom severity was obtained from all subjects and its relationship with the maximal ingested volume was determined. The maximal ingested volume was registered and the subjective symptoms were assessed at baseline and 30 min after the WLT.
RESULTS: The maximal ingested volume by HC was 597 +/- 33 ml, which was statistically greater than that of FD (422 +/- 22 ml, p < 0.001) and GERD (504 +/- 23 ml, p < 0.02) subjects. The maximal ingested volume did not differ significantly between FD and GERD. The maximal ingested volume correlated well with nausea (r = -0.49, p < 0.01) and fullness (r = -0.33, p < 0.05) in FD. Male subjects ingested more water than females in the HC (p < 0.01) and GERD groups (p < 0.05), but not in FD (p = NS).
CONCLUSIONS: Both FD and GERD subjects have altered perception to gastric fullness induced by the WLT compared to healthy controls. Good correlations have been observed between the WLT and dyspeptic symptoms such as early satiety and postprandial fullness, but not in GERD.
