Fiber Regimens for Constipation Symptoms

Randomized Trial Comparing Two Fiber Regimens for the Reduction of Symptoms of Constipation

The objective of the current study is to compare the effects of bowel recipe with psyllium on symptoms associated with constipation.

Patients presenting to the urogynecology clinics at Parkland Health and Hospital System and UT Southwestern Medical Center at Dallas from July 2003 to July 2005 were screened for symptoms of constipation. Subjects were randomized to a 6-week course of either psyllium (Konsyl, Konsyl Pharmaceuticals, Easton, MD) or a special bowel recipe. The bowel recipe was a modification of that used by Behm and consisted of 1 cup of unprocessed wheat bran, 1 cup of applesauce, and 1/4 cup of prune juice. A validated constipation scoring questionnaire12 was administered to participants at the beginning and at the end of the six-week study period. During the six-week trial patients also kept a bowel diary recording characteristics of each bowel movement.
