Gas. The most common cause is lactose intolerance. Try avoiding milk and milk products for 3 weeks and you might notice improvement. Also, you can try lactaid tabs or probiotics.
Diet related. Mostly diet related; excess raw fruits and vegetables can cause; see if any changes in your diet help; also avoid a lot of caffeine, assure bowel regularity; it is normal to pass gas. Try over the counter gas reducing meds if severe.
