"constipation" is usually understood to imply infrequent bowel evacuations or difficult passage of feces persisting for a few weeks. It is one of the commonest medical complaints affecting patients of all ages, with an estimated uk prevalence varying from 8.2% to 52% [1]. Its incidence increases with age and is higher in those of lower socioeconomic class and with lower educational status [2].
