title: Gastric emptying rate of solids in patients with nonulcer dyspepsia.
abstract: The underlying role of motility disorders and delayed gastric emptying in nonulcer dyspepsia is still questioned. This study aimed to determine the role of the gastric emptying rate of solids in patients with nonulcer dyspepsia. By means of breath test technology, gastric emptying results of 344 consecutive patients with nonulcer dyspepsia were compared with those of 70 normal healthy volunteers. Although gastric emptying was significantly delayed in patients with nonulcer dyspepsia compared with normal volunteers, there was a great overlap between the two groups. Using 5-95% confidence intervals of the control group in about 30% of the patients with nonulcer dyspepsia gastric emptying was delayed. No correlation was found between gastric emptying rate and age, weight, height, or sex of the subjects in both groups. These findings suggest that, apart from gastric emptying, other mechanisms are very important in the etiology of nonulcer dyspepsia.
