Flatulence, or gas, is actually a normal bodily function and, in fact, it is quite healthy. Flatulence is the by-product of digestion, although when cancer treatment causes severe flatulence and/or lower abdominal pain, measures can be taken to minimize the treatment's effects.
It is important you find a cause of trapped gas, which may be: 1  Certain food irritating your bowel: Foods to avoid in IBS. Food poisoning. 2  Abdominal adhesions created after abdominal surgery, pelvic inflammatory disease (PID), endometriosis or trauma. 3  Intestinal obstruction. 4  Other causes of upper abdominal bloating.
