Bloating is one of the most common gastrointestinal complaints that is attributed by the patient as the subjective sensation of incorrectly perceived excess gas. There are multiple non-functional etiologies of abdominal bloating and distension. Primary functional abdominal distension (FABD) should be diagnosed as a single entity and doesn't overlap with other functional gastrointestinal disorders. Rome IV diagnostic criteria mentions the co-existence of mild abdominal pain and/or minor bowel movements. FABD can be treated with antispasmodic along with peppermint oil in randomized controlled trials. A stepwise approach is usually needed that includes the dietary interventions, microbiome modulation, and medical therapy in the management of FABD.
Complete Diagnostic Approach
Artificial sweeteners containing sorbitol, mannitol, and xylitol should be avoided. 
Medications such as anticholinergics, opiates, calcium channel blockers, and antidepressants should also be avoided as they have an effect on bloating.  20% of carbohydrates in baked beans, 7–10% in wheat, oats, potatoes, and corn, and 1% in white rice are not absorbed well in the intestine and they can predispose to bloating, hence it is advisable to avoid them in the patients with increased complaints of bloating.
