Flatulence is a condition of having excessive gas in the stomach or intestine. This may cause a great deal of discomfort and may lead to other embarrassing symptoms like burping or belching.

The gas (flatus) formed in the stomach or intestine is a by-product of digestion.


The primary gases in flatus include nitrogen, hydrogen, carbon-di-oxide, oxygen and methane. The characteristic odor of flatus is attributed to the by- products of digestion including, sulphur compounds and certain bacteria present in the GI tract.
