Abstract
In the present study the prophylactic effect of concentrated wheat fibre on duodenal ulcer recurrence was evaluated. Eleven grams of fibre (Fiberform®) or placebo was added to an ordinary Norwegian diet for 1 year after endoscopic healing of duodenal ulcer. The ulcer recurrence rates were 84% (31 of 37 patients) in the fibre-supplemented group and 85% (30 of 36 patients) in the placebo group (NS). The effect on ulcer symptoms was similar in both groups. Side effects were infrequently seen. A concentrated wheat fibre supplement seems to have no preventive effect when given to duodenal ulcer patients living on a traditional Norwegian diet.
