Outcomes
Primary outcome [1] 329061 0
Change in severity of experiencing abdominal bloating/distension using Gastrointestinal Symptom Rating Scale (GSRS) to assess the severity and frequency of symptoms,

The Gastrointestinal Symptom Rating Scale (GSRS) is a disease-specific questionnaire of 15 items to assess the severity and frequency of symptoms was reported; GSRS uses a 7-point Likert scale ranging from 1 = no problem to 7 = a very severe problem.

Summary
Brief summary
Irritable Bowel Syndrome is part of a range of disorders classified as a “Functional Gastrointestinal Disorders”. IBS is referred to as a FGID, as the person experiences uncomfortable and often intrusive symptoms; however, on medical investigation (either endoscopy, colonoscopy or other non invasive tests), no medical abnormalities are found. As a result, the issue is regarded as being to do with the functioning of the gut or the gut-brain interaction, rather than organic disease.

This condition may cause intestinal microflora imbalance, and in the long term may lead to constipation, diarrhea, gastroenteritis, gastric ulcer, and other gastrointestinal diseases. Post antibiotic treatment tend to affect the diversity of intestinal microflora, causing diarrhea, flatulence, and nausea. This project aims to observe the effectiveness of deactivated Bacillus subtilis strain BG01-4™ consumption by patients in relieving the gastrointestinal symptoms and restoring their intestinal microflora.
