Primary | : Change in complete spontaneous bowel movement (CSBM) | Complete spontaneous bowel movement will be recorded. This will be compared to the baseline, run-in periods, and follow-up period. | 8 weeks | |
Secondary | Change in SBM (spontaneous bowel movements) | Spontaneous bowel movements will be recorded. This will be compared to the baseline, run-in periods, and follow-up period. | 8 weeks | |
Secondary | stool consistency | Bristol stool form scale (1-7, lower scores are consistent with constipation; higher scores are consistent with diarrhea) will be recorded. This will be averaged and compared to the baseline, run-in period, and follow-up period. | 8 weeks | |
Secondary | straining | 5 point Likert scale for straining will be recorded (1-5, lower scores= less straining, higher scores = more straining). This will be averaged and compared to the baseline, run-in periods, and follow-up period. | 8 weeks | |
Secondary | abdominal pain | Daily score (0-10) for abdominal pain will be recorded (0=no pain, 10= severe pain). This will be averaged and compared to the baseline, run-in periods, and follow-up period. | 8 weeks | |
Secondary | abdominal discomfort | Daily score (0-10) for abdominal discomfort will be recorded (0=no pain, 10= severe pain). This will be averaged and compared to the baseline, run-in periods, and follow-up period. | 8 weeks | |
Secondary | bloating | Daily score (0-10) for abdominal bloating will be recorded (0=no pain, 10= severe pain). This will be averaged and compared to the baseline, run-in periods, and follow-up period. | 8 weeks |
