Atopic irritable bowel syndrome: a novel subgroup of irritable bowel syndrome with allergic manifestations

Adults with atopic symptoms report a high incidence of IBS, suggesting a link between atopy and IBS. We proposed a subgroup of patients with IBS (atopic IBS) who have typical IBS symptoms in association with atopic manifestations. Identifying atopic vs nonatopic IBS may help in identifying the underlying pathophysiologic mechanisms and therapeutic options.
