Fruit and fibre (Pajala porridge) in the prevention of constipation

Background and Aims: Constipation is a common problem in geriatric wards and in the elderly population. Although high‐fibre diets can help relieve constipation non‐pharmacologically in many patients, traditional laxatives still remain the standard treatment. A fibre supplement in the form of raw bran is not always well tolerated. We wanted to study the effects of a daily consumption of a fruit‐ and fibre‐rich porridge on stool frequency, perceived well‐being and the costs for laxatives, when compared with traditional treatment with laxatives, in geriatric patients. Methods: Twenty patients in secondary geriatric wards (hospital rehabilitation wards) were randomized into an intervention group (porridge group) and a control group (standard diet without porridge) for a 1‐week run‐in and 2‐week study, with registration of clinical data, e.g. medical treatment, laxative consumption, stool frequency and perceived well‐being. Results: The patients in the porridge group had a daily defaecation without laxatives on average 76% of the time (10.7/14 days) compared with 23% of the time (3.3/14 days) in the non‐porridge group (p = 0.003). The discomfort was less in the porridge group (2.5 vs. 6.5 on a 10‐degree visual analogue scale, p = 0.008) when compared with the control group. The cost for laxatives was 93% lower in the intervention group (2.5€ vs. 37.5€) for the 2‐week study. Conclusions: A fibre‐rich porridge was effective, well liked and tolerated and reduced the need for laxatives in geriatric patients. We conclude that a daily fibre‐rich meal ought to be included in the treatment strategies of constipation in hospital wards.
