Effect of Bacillus Coagulans in Adults With With Functional Constipation

Effect of Bacillus Coagulans on Various Symptoms and Fecal Microbial Diversity in Adults With With Functional Constipation: a Randomized, Double-blinded, Placebo-controlled Trial

The investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of Bacillus coagulans on various symptoms and fecal microbial diversity in adults with with functional constipation for 12 weeks.

A previous study has indicated that Bacillus coagulans provided control of abdominal pain, less discomfort during defecation, and a more normalized defecation style, especially in adults with with functional constipation. Therefore, the investigators conduct a randomized, double-blind, placebo-controlled study to investigate the effects of Bacillus coagulans various symptoms and fecal microbial diversity in adults with with functional constipation for 8 weeks; the safety of the compound are also evaluated. The Investigators examine constipation visual analogue scale, Bristol Stool Form Scale type 3 & 4 ratio, visual analogue scale for irritable bowel syndrome (VAS-IBS) questionnaire score, IBS-symptom severity scale, IBS quality-of-life questionnaire score, fecal microbial diversity at baseline, as well as after 8 weeks of intervention. Eighty adults were administered either 400 mg of Bacillus coagulans or a placebo each day for 8 weeks.
