Functional bowel disorders comprise a spectrum of chronic gastrointestinal (GI) disorders characterized by abdominal pain, bloating, distention, and/or bowel habit abnormalities (constipation, diarrhea, or mixed constipation and diarrhea) in the absence of any organic or biochemical pathology.1,2 These are primarily attributed to the deranged functioning of the well-coordinated brain- gut axis that results in an array of symptoms that can affect any part of GI tract.3 Irritable bowel syndrome (IBS) is a highly prevalent functional bowel disorder characterized by symptoms of abdominal pain or discomfort that occur with changes in bowel function.
