Background : Dysmotility of the gastroduodenal region and delayed gastric emptying have been considered to play roles in non‐ulcer dyspepsia. In addition, it has been reported that Helicobacter pylori induced inflammation of the gastric mucosa may affect gastric motility. Aim : To evaluate the effects of H. pylori eradication therapy on gastrointestinal motility and symptoms in non‐ulcer dyspepsia patients. Methods : A total of 46 non‐ulcer dyspepsia patients were examined for gastric emptying, antral myoelectrical activity, H. pylori infection, and symptom scores. In H. pylori ‐positive non‐ulcer dyspepsia patients, gastric emptying, antral myoelectrical activity, and symptom scores were also analysed 2 months after being cured of H. pylori infection. Results : A total of 67.4% of the non‐ulcer dyspepsia patients were H. pylori ‐positive. Both abnormal gastric emptying and antral myoelectrical activity were observed in non‐ulcer dyspepsia patients. H. pylori ‐positive non‐ulcer dyspepsia patients were divided into three groups according to their gastric emptying: the delayed gastric emptying group, the normal gastric emptying group, and the rapid gastric emptying group. In the delayed and rapid gastric emptying groups, the gastric emptying and symptom scores were improved significantly by the eradication therapy. However, there was no improvement in symptom scores in the normal gastric emptying non‐ulcer dyspepsia group by the eradication therapy. Conclusions : Disturbed gastric emptying and antral myoelectrical activity play roles in non‐ulcer dyspepsia. Helicobacter pylori infection, inducing disturbed gastric emptying, may cause some non‐ulcer dyspepsia symptoms. Gastric emptying and symptom scores are improved by H. pylori eradication therapy in non‐ulcer dyspepsia patients with disturbed gastric emptying. H. pylori eradication therapy is effective in H. pylori ‐positive non‐ulcer dyspepsia patients with disturbed gastric emptying.
