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.
Sometimes stomach gas causes nausea and poor appetite. Gas in the stomach may remain for a time before releasing. Too much stomach gas may cause an upset stomach. Stomach gas may remain in the stomach longer in patients who have an irritable bowel syndrome, ulcer or other digestive condition.
