Bloating is very common in patients with irritable bowel syndrome and constipation, and also occurs in patients with organic disorders and psychiatric conditions.

The possible causes of functional bloating are combination of several factors such as gut microflora, gas production, intestinal transit, intestinal propulsion of gas, and sensory function within the gastrointestinal tract. Evaluation of a patient with bloating should begin with a careful history and physical examination to rule out an organic disorders. Reassurance and education are the first essential step as a treatment for functional bloating. The therapeutic approach involving diet, probiotics, and medications usually improve bloating.
