Gas in your digestive tract (the esophagus, stomach, small intestine, and large intestine) comes from two sources- swallowed air and the normal breakdown of certain undigested foods by harmless bacteria that are naturally present in the large intestine. 

Excess gas/bloating due to increased swallowed air may be caused by eating or drinking rapidly, talking while eating, chewing gum, smoking, or wearing loose dentures.

Excess gas/bloating due to an increased production of gas, a by-product of food digestion by naturally occurring bacteria, is commonly encountered. Bacteria are responsible for digesting materials like complex carbohydrates (sugar, starches, and fiber found in many foods) and cellulose, which are not normally digested in the upper gastrointestinal tract. The quantity and mixture of gases depends on the types of bacteria in the gastrointestinal tract. 

Burping or belching is a way swallowed air leaves the stomach. Gas in the gastrointestinal tract moves down the small intestine, into the colon and is subsequently released through the rectum as flatulence. Excess gas trapped in your intestines or passed as flatulence, can become uncomfortable and painful. Furthermore, excess gas/bloating may be a sign of significant underlying disease such as pancreatic disorder, ovarian cancer or gastric cancer. Thorough evaluation of excess gas/bloating should be performed by a gastroenterologist.
