Dietary fibre supplementation with psyllium or gum arabic reduced incontinent stools and improved stool consistency in community living adults.

Intervention Participants were allocated to receive 31 days of dietary fibre supplementation with psyllium, 7.1 g/day (n=13), or gum arabic, 25 g/day (n=13); or placebo given as pectin, 0.25 g/day (n=13). Supplementation was mixed into fruit juice and divided into 2 servings for consumption during the morning and evening meals. Participants were instructed to maintain their usual diet, and those who were taking antidiarrhoeal medication were advised not to alter the type and amount during the study. No participant had biofeedback training for pelvic muscle exercises.
