Constipation is a common problem in children. Most patients have functional constipation, with or without soiling. The treatment program for functional constipation includes various forms of behavioral therapy and psychological approaches, and consists of education, disimpaction, prevention of reaccumulation of stools with fiber and laxatives, and reconditioning to normal bowel habits with frequent toileting. Most patients experience dramatic improvement in constipation and soiling. Complete recovery, defined as three or more bowel movements per week with no soiling while off laxatives, is seen less frequently, and often requires years of treatment.
