Wheat bran in dyschezia in the aged.

A trial of wheat bran added to the diet of aged dyschezic hospital patients (12 men, 13 women) is reported. This significantly reduced the need for aperients and suppositories but revealed unexpected differences in response by sex. In men, bran produced more bowel actions, fewer constipated days and an increase in stool size. In women there was much less effect upon the number of bowel actions and reduction of constipated days. In men there were fewer constipated days and need for aperients after the bran was withdrawn. Side-effects were only seen in men. Most patients received 15 g/day (range 5-25 g/day). Although cheap and effective in replacing aperients, there were problems in administration and control of incontinence for the nursing staff. The value of added wheat bran in the bowel management of the long-stay hospital patient is discussed and an effective method of combining bran in the diet (e.g. with bread) might be further investigated.
