Outcome Measures
Primary Outcomes (2)
The change of stool form
The stool type will be assessed by The Bristol Stool Form Scale (BSFS). The BSFS is a scale that classifies stools, ranging from the hardest (type 1) to the softest (type 7).
Week 0 (Baseline), Week 2, Week 4
The change of bowel movement and gastrointestinal discomforts
The Gastrointestinal Symptom Rating Scale (GSRS) will be utilized to assess the bowel movement and gastrointestinal discomforts. The GSRS consists of 15 items, each rated on a 7-point Likert scale. A higher score indicates more severe and frequent symptoms.The total GSRS score is calculated by taking the average score of the five symptom categories- Reflux, Abdominal Pain, Indigestion, Diarrhea, and Constipation- summing them up, and then dividing the total by five to obtain the overall mean score.
