Outcome(s)

Primary OutcomeAmount of change in defecation score* on the Bristol Stool Form Scale between pre-treatment and treatment week 8 (day 56). *The stool properties score (1-7) on the Bristol Scale is used as the score, and the score is set to "0" on days when there is no defecation. Defined as the total of the values obtained by subtracting 4, which is considered to be a normal stool on the Bristol Scale, for 7 consecutive days. If there is a missing measurement in seven consecutive days, the average value of the data excluding the missing days is adopted.
Secondary Outcome1. Amount and rate of change in the number of bowel movements (7-day average) between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56). If there is a missing measurement in seven consecutive days, the average value of the data excluding the missing days is adopted. 2. Amount of change in the defecation score of the Bristol Stool Form Scale between pre-treatment and treatment week 4 (day 28). 3. Amount and rate of change in JPAC-QOL total score and each subscale score between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56). 4. Amount and rate of change in ModifiedCSS (mCSS) total score and each endpoint between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56). 5. Amount and rate of change in each questionnaire score between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56). Izumo scale, and DVS (food diversity questionnaire) 6. Amount and rate of change in the severity of strain score (7-day average) between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56). *: The difference in the severity of strain is in 5 levels (1: no strain, 2: slight strain, 3: some strain, 4: strong strain, 5: very strong strain) If there is a missing measurement in seven consecutive days, the average value of the data excluding the missing days is adopted. 7. Amount and rate of change in TG/HDL-C ratio between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56). 8. Amount and rate of change in nutritional status assessment between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56). 9.Variation and rate of change in intestinal microflora between pre-treatment and treatment week 4 (day 28), and between pre-treatment and treatment week 8 (day 56) Comparison of intestinal microbiota (Butyrate-producing bacteria occupancy and others), diversity analysis, principal coordinate analysis, LEfSe analysis
