Effectiveness of the low FODMAP diet in patients with irritable bowel syndrome and small intestine bacterial overgrowth syndrome

Low FODMAP diet was well tolerated and reduced reported gastrointestinal symptoms, with the greatest effect on reducing bloating. The reduction in symptoms occurred independently of the initial diagnosis. Patients who completed both phases of the diet were taking antibiotics before the diet more likely to respond well to the low FODMAP diet. The diet proved difficult to follow, and more than half of the patients sought the support of a dietitian, which confirms the importance of such support.
