Abstract

AIM:

To investigate if increased dietary fiber, in terms of kiwifruit, is effective in Chinese constipated patients.

METHODS:

33 constipated patients and 20 healthy volunteers were recruited for a 4-wk treatment of kiwi fruit twice daily. Response during wk 1-4 was defined as an increase in complete spontaneous bowl, motion (CSBM) > or = 1/wk. Secondary efficacy included response during wk 1-4, individual symptoms and scores of bowel habits and constipation. Responses were compared with the baseline run-in period. Colonic transit time and anorectal manometry were performed before and after treatment.

RESULTS:

Responder rate was 54.5% in the constipated group. The mean CSBM increased after treatment (2.2 +/- 2.6 vs 4.4 +/- 4.6, P = 0.013). There was also improvement in the scores for bothersomeness of constipation (P = 0.02), and satisfaction of bowel habit (P = 0.001), and decreased in days of laxative used (P = 0.003). There was also improvement in transit time (P = 0.003) and rectal sensation (P < 0.05). However, there was no change in the bowel symptoms or anorectal physiology in the healthy subjects.

CONCLUSION:

Increasing dietary fiber intake is effective in relieving chronic constipation in Chinese population.
