The 73rd Annual Scientific Meeting of the American College of Gastroenterology in Orlando saw several studies presented relating to the efficacy and safety of using probiotics in the treatment of irritable bowel syndrome. Probiotics were found both to alleviate symptoms and help normalize the frequency of bowel movements for patients suffering diarrhea or constipation relating to Irritable Bowel Syndrome (IBS). Dr. Paul Moayyedi and colleagues of several universities undertook a meta-analysis which was then presented at the ACG Annual Scientific meeting in Orlando.
