Background:

Flatulence is the accumulation of excessive gas in the stomach or intestine. Because flatulence may be socially embarrassing, it is one of the most common complaints encountered in medical practice. Although a number of factors have been implicated in its pathogenesis, sometimes no cause can be found and it may therefore prove refractory to treatment.
