What Causes Flatulence?
By Dr Ananya Mandal, MD
Flatulence or passing wind is a normal biological process and, on average, a person passes wind around fifteen times each day. Flatulence is caused by a build up of small amounts of swallowed air and as a result of the gases produced when bacteria break food down in the gut. However, excessive flatulence can become embarrassing and people with this problem can take several measures to alleviate their symptoms.
