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.
Build up of excess gas can be caused due to many factors which include constipation, water retention, trapped air, overeating, indigestion, smoking and others. Bloating is generally accompanied by other problems like diarrhoea, lower back pain, belching, gas and stomach cramps.
