What are the most effective nonpharmacologic therapies for irritable bowel syndrome?

Abstract

Herbal formulations, certain probiotics, elimination diets based on immunoglobulin G (IgG) antibodies, cognitive behavioral therapy, and self-help books have been shown to decrease global symptoms of irritable bowel syndrome (IBS) and improve overall quality of life (strength of recommendation [SOR ]: B). For patients with severe refractory IBS, hypnosis has been shown to relieve symptoms (SOR : B). Soluble fiber is more effective than insoluble fiber at improving global IBS symptom ratings (SOR : C).
