Mast cells are implicated in both IBS and to a lesser extent in functional dyspepsia.2 These cells release, among other mediators, histamine, which acts on histamine receptors on submucosal neurons, as well as on epithelial cells causing secretion of chloride and bicarbonate.2 Histamine-2 receptor blockade …
