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.
A buildup of gas leads to bloating, or a swelling of the stomach and abdomen. This swelling can make your stomach feel hard, sometimes brings pain and might make you feel general discomfort. This is often caused by various foods or beverages, swallowed air, some medical conditions, constipation or medications.
